an ant walks due east at a constant speed of on a sheet of paper that rests on a table. suddenly the sheet of paper starts moving southeast at . describe the motion of the insect relative to the table.

Answers

Answer 1

When the sheet of paper starts moving southeast at a constant speed, the motion of the ant relative to the table becomes a combination of two motions: the ant's original motion due east and the motion of the sheet of paper southeast.

What is relative motion of ant?

To describe the motion of the insect relative to the table, we need to take into account both the ant's original motion and the motion of the sheet of paper. The ant's original motion due east at a constant speed can be represented as a vector, and the motion of the sheet of paper southeast can be represented as another vector. The sum of these two vectors represents the motion of the ant relative to the table.

Mathematically, if we represent the ant's original motion due east as a vector with magnitude and direction, and the motion of the sheet of paper southeast as a vector with magnitude and direction , then the motion of the ant relative to the table can be represented as the sum of these two vectors.

In this case, the ant's original motion due east and the motion of the sheet of paper southeast are both at right angles to each other, so the sum of the two vectors can be represented using the Pythagorean theorem. The magnitude of the resulting vector can be calculated as the square root of the sum of the squares of the magnitudes of the two vectors.

The direction of the resulting vector will be southeast, but the exact angle will depend on the magnitudes of the original vector and the vector representing the motion of the sheet of paper.

a block starts at rest and slides 5 meters down a frictionless incline with angle 36.87 degrees between the incline and the horizontal. what is the speed of the block after sliding this 5 meters?

Answers

Using conservation of energy, The speed of the block after sliding this 5 meters 3.76 m/s

What exactly is energy conservation?

The conservation of energy is a fundamental principle of physics, according to which energy can only be transformed from one form to another and cannot be created or destroyed. In a closed system, the total amount of energy stays constant even though the forms and distribution of the energy may change.

This theory's fundamental tenet is that energy is a property of matter and that it is preserved while matter moves and assumes various forms. There are many other forms that energy can take, including kinetic energy (movement), potential energy (position), thermal energy (heat), electrical energy (electricity), chemical energy (chemical processes), and nuclear energy (nuclear reactions).

The idea of energy conservation is essential to many scientific and engineering fields, including energy management, physics, thermodynamics, and mechanics.

The equation for the conservation of energy can be used to determine the block's speed after sliding 5 meters down a frictionless incline at an angle of 36.87 degrees from the horizontal:

v² = 2gh

If h is the vertical height to which the block has fallen, given by h = 5 sin, and v is the block's final velocity, g is the acceleration caused by gravity (about 9.8 m/s) (36.87).

Substituting these values, we find that:

imagine two students 10 m away from each other, each losing 0.01% of his electrons. find the repulsion force in kn (kilo-newtons).

Answers

The required repulsion force is 1.11 x 10^-14 kilo-newtons.

What is Coulomb's law?

The repulsion force between two electrons can be calculated using Coulomb's law, which states that the force between two point charges is proportional to the product of the charges and inversely proportional to the square of the distance between them. The formula for the force is given by:

F = k * (q1 * q2) / r^2

where F is the force in newtons, k is the Coulomb constant (8.99 x 10^9 N m^2/C^2), q1 and q2 are the magnitudes of the charges in coulombs, and r is the distance between them in meters.

Since electrons have a negative charge, the force between them is repulsive. If each student loses 0.01% of their electrons, the force can be calculated as follows:

q1 = q2 = (0.01%) * (1.6 x 10^-19 C) = 1.6 x 10^-21 C

r = 10 m

Substituting these values into the formula gives:

F = k * (q1 * q2) / r^2 = 8.99 x 10^9 N m^2/C^2 * (1.6 x 10^-21 C)^2 / (10 m)^2 = 1.11 x 10^-11 N

Converting the force from newtons to kilo-newtons gives:

F (in kn) = F (in N) / 1000 N/kn = 1.11 x 10^-11 N / 1000 N/kn = 1.11 x 10^-14 kn

So, the repulsion force between the two students, each losing 0.01% of their electrons, is approximately 1.11 x 10^-14 kilo-newtons.

Answers

7.66 x 10⁷ m/s is the speed as it enters the magnetic field if an electron is accelerated by a potential difference of 3000v.

The radius of curvature of an electron in a magnetic field is given by the equation:

[tex]r=\frac{mv}{(qB)}[/tex],

where m is the mass of the electron, v is its velocity, q is its charge, and B is the magnetic field.

Knowing the radius of curvature and the charge and mass of an electron, magnetic field we can rearrange the equation to find the velocity:

[tex]v = \frac{qB * r}{m}[/tex].

Substituting the known values:

v = (1.6 x 10⁻¹⁹ C) * (B) * (26.0 cm) / (9.11 x 10⁻³¹ kg)

Since the electron is accelerated by a potential difference of 3000V, we can calculate its kinetic energy using the equation:

K = 0.5 * m * v²,

and then use that to find the velocity:

K = eV = 0.5 * m * v²,

where e is the electron charge, and V is the potential difference.

Solving for v:

v = √(2 * eV / m) = √(2 * (1.6 x 10⁻¹⁹ C) * (3000 V) / (9.11 x 10⁻³¹ kg)) = 7.66 x 10⁷ m/s.

a ball is thrown directly up from a height of 0m with an initial speed of 2m/s. calculate the height of the apex of the throw

Answers

A ball is thrown directly up from a height of 0m with an initial speed of 2m/s. The height of the apex of the throw is approximately 0.825 meters.

The height of the apex of the throw can be calculated as follows:

h = vi * t - 0.5 * g * t^2

where:

vi = initial velocity = 2 m/s (up)

t = time of flight = 2 * vi / g

g = acceleration due to gravity = 9.8 m/s^2

Plugging in the values, we get:

t = 2 * 2 / 9.8 = 0.408 seconds

h = 2 * 0.408 - 0.5 * 9.8 * 0.408^2

h = 0.825 meters

Equation 2.3 is derives using

this is the equation for the final velocity or the velocity of an object accelerating with "a" for time t. In the Equation 2.3, a is not g, indeed its the acceleration of the object which was initially moving with velocity v₀, has an acceleration for time t.

For a projectile motion, in all the equations of motion we take a = g = 9.81 m/s², since the only acceleration that a projectile has is that due to gravity.

The value of acceleration due to gravity is calculated using

g = G M/R² ; where G is the universal gravitational constant; R is the radius of the earth and M is its mass.

What is the speed of cart 1 right after the collision if the collision is elastic? Express your answer in terms of v.

Answers

If the impact is elastic, Cart 1's immediate post-contact speed is;

v₁ = ¹/₃u₁ oras one-third of the speed it had before the accident

As a result of the collision's elastic nature, we may state that;

u₁ + v₁ = u₂ + v₂  ---(eq 1)

Also, we can say that;

m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂  ---(eq 2)

Let us make v₂ the subject in eq 1 and put in eq 2;

v₂ = u₁ - u₂ + v₁   ----(eq 3)

Thus;

m₁u₁ + m₂u₂ = m₁v₁ + m₂(u₁ - u₂ + v₁)

making v₁ the subject gives;

v₁ = [(m₁ - m₂)/(m₁ + m₂)]u₁ + [2m₂/(m₁ + m₂)]u₂

We are informed that Cart 1 is twice as fast as Cart 2. Thus;

u₂ = ¹/₂v₁ =  ¹/₂u₁

The momentum of cart 2 is also double that of cart 1's.

Thus, m₂ = 2m₁

Plugging in the values gives;

v₁ =  [(m₁ - 2m₁)/(m₁ + 2m₁)]u₁ + [2(2m₁)/(m₁ + 2m₁)]( ¹/₂u₁)

Answers

The angle of projection of the fired projectile is θ = sin⁻¹[tex]\frac{(g*R)}{(6*V_{0} ^{2} )}[/tex]/2

The horizontal range of a projectile is given by the equation:

R = V₀² * sin(2θ) / g

where R is the horizontal range, V₀ is the initial velocity, θ is the angle of projection, and g is the acceleration due to gravity (approximately 9.8 m/s²).

Given that the horizontal range is equal to 12 times the maximum height, we can use the following equation for the maximum height:

H = V₀² * sin²(θ) / 2g

So, we can substitute the expression for H into the equation for R to get:

R = 12 * V₀² * sin²(θ) / 2g

Now we can equate the two expressions for R and solve for θ:

R = V₀² * sin(2θ) / g = 12 * V₀² * sin²(θ) / 2g

2g * R = V₀² * sin(2θ) = 12 * V₀² * sin²(θ)

sin(2θ) = (2g * R) / (12 * V₀²)

connect the short open-ended bnc cable to the vna. how does the smith chart display change? is this consistent with your understanding? now connect the longer bnc cable to the output. measure the length of the cable with a ruler and estimate the wavelength in the cable and the effective dielectric constant of the cable. is there any indication of increasing losses in the bnc cable as frequency increases?

Answers

When you connect a short, open-ended BNC cable to the VNA, the Smith chart display will not change, as the open-ended cable will not affect the impedance of the measurement. When you connect a longer BNC cable to the output], the Smith chart will change depending on the length of the cable and the frequency of the signal. The longer the cable, the bigger the change will be.

You can measure the length of the cable with a ruler and estimate the wavelength in the cable. The effective dielectric constant of the cable can be estimated using the formula εr = (c/v)2 - 1, where c is the speed of light and v is the velocity factor of the cable.

There may be an indication of increasing losses in the BNC cable as frequency increases, as higher frequencies will be attenuated more than lower frequencies.

if the ages of the earth and the moon are nearly identical, as believed, why are most rocks found on the moon so much older than rocks found on earth? group of answer choices

Answers

In contrast to the Earth, which has an atmosphere that weathers rocks and plate tectonic activity that breaks up rocks, if the ages of the Earth and the Moon are approximately equal as is thought, then the moon does not.

Why does the rock on the Moon have a longer age than the rock on Earth?

That's because the moon most likely developed following a rogue, Mars-sized planet's early solar system collision with the newborn Earth.

Why are Earth's rocks younger than those on Mars and the Moon?

On Earth, similar rock types that have been sculpted by melting, volcanism, and collisions are present. The earliest rocks on Earth were destroyed by weathering and plate tectonics. Moon rocks are older than any previously discovered ones.

what is the voltage between two points if 1.2 j of energy are required to move 10 mc between the two points?

Answers

The voltage between two points if 1.2 j of energy are required to move 10 mc between the two points is 120 V.

Voltage difference, also known as voltage drop or electrical potential difference, is the measure of the electric potential energy difference between two points in an electrical circuit. The voltage difference between two points determines the amount of energy required to move a unit of electric charge between those two points.

Voltage can be calculated using the formula:

V = ΔE / ΔQ

where ΔE is the change in energy and ΔQ is the change in charge. In this case, ΔE = 1.2 J and ΔQ = 10 mc, so:

V = ΔE / ΔQ = 1.2 J / (10 mc) = 120 V

Therefore, the voltage between the two points is 120 V.

What is integration of rational functions by partial fractions?

Answers

The  integration of rational functions by partial fractions is a/(x-p) + b/(x-q) + ... + n/(x-z). The indefinite integral of each partial fraction can be found by  ∫f(x)dx = 2 ln(x-1) + ln(x+1) + C, where C is the constant of integration.

How can one determine when to integrate partial fractions?

If the degree of the denominator is significantly smaller than the degree of the numerator, only partial fractions are possible. It's crucial to note this. You must factor the denominator as completely as feasible once you have realized that partial fractions can be calculated.

How are fractions integrated?

The top and bottom of the fraction must be multiplied or divided by a number if you are asked to integrate a fraction. Sometimes it will be beneficial to divide a fraction into smaller parts before attempting to integrate it. For this, you can employ the partial fractions method.

two blocks are attached by a thin inextensible string over a frictionless, massless pulley. there is a frictional force between the block on the incline and the incline. the acceleration of gravity is 9.8 m/s 2 .calculate the magnitude of the frictional force acting on the block on the incline. answer in units of n. answer in units of n. 010

Answers

The magnitude of the frictional force acting on the block on the incline  is m2 * 9.8 N

Given the following information:

Block 1 has mass m1

Block 2 has mass m2

Block 1 is on an incline with an angle theta concerning the horizontal

The frictional force acting on block 1 has magnitude of

The forces acting on block 1 can be analyzed as follows:

The gravitational force acting downwards: m1 * g (where g = 9.8 m/s^2)

The normal force acting upwards: N = m1 * g * cos(theta)

The frictional force acting up the incline: f

By Newton's second law, the net force acting on block 1 is equal to its mass times acceleration:

m1 * a = m1 * g * sin(theta) - f

Where a is the acceleration of block 1. Since the block is not moving, the acceleration must be zero:

0 = m1 * g * sin(theta) - f

Solving for the magnitude of the frictional force, we get:

f = m1 * g * sin(theta) = m1 * 9.8 m/s^2 * sin(theta)

The net force acting on block 2 is equal to its mass times acceleration, which must be equal and opposite to the net force acting on block 1 to balance the tension in the string:

m2 * g = f

So, the magnitude of the frictional force acting on the block on the incline is:

f = m2 * g = m2 * 9.8 m/s^2

Answer in units of N:

f = m2 * g = m2 * 9.8 m/s^2 * (1 N/1 kg * m/s^2) = m2 * 9.8 N
