The voltage drop can be seen from the full circuit diagram.

A voltage drop in a circuit refers to the decrease in voltage (electrical potential difference) along a conductor as electric current flows through it. It is caused by the resistance of the conductor, which resists the flow of electric current, thus converting some of the electrical energy into heat.

Voltage drop is an important consideration in electrical circuit design, particularly in long or complex circuits, because it affects the amount of voltage available to power electrical devices. If the voltage drop is too large, the devices may not operate correctly, or they may be damaged.

The car that comes to a complete stop has:

a) A constant acceleration in ft/sec of: -27.06 ft/sec²

b) A stopping distance, (in ft) from an initial speed of 70 mi/hr of: 194.50 ft

It is a physical quantity that indicates the variation of velocity as a function of time, it is expressed in units of distance per time squared e.g.: m/sec2 ; km/h2

The formulas for uniformly varied rectilinear motion (UVRM) and procedures we will use to solve this exercise are:

Where:

Information about the problem:

By Converting the velocities from (mi/hr) to (ft/sec) we have:

vi1= 55 mi/hr /* 5280 ft/ 1 mi * 1 hr/3600 sec

vi1= 80.6 ft/sec

vi2= 70 mi/hr /* 5280 ft/ 1 mi * 1 hr/3600 sec

vi1= 102.6 ft/sec

Applying the acceleration formula we get:

a = ((vf²- vi²) /2* x

a = [(0 ft/sec) ²- (80.6 ft/sec )² /2* 120 ft

a = [0 ft²/sec²- 6496.36 ft²/sec² /240 ft

a = -27.06 ft/sec²

Acceleration is negative because the car is decelerating

Applying the distance formula, we get:

x = (vf²-vi²)/ (2a)

x2 = [(0 ft/sec)²- (102.6 ft/sec)²]/ (2 * -27.06 ft/sec²)

x = (0 ft²/sec²- 10526.76 ft²/sec²)/ -54.12 ft/sec²

The force would be one-fourth as much.

Force is a push upon an object resulting from its interaction with another object. It is a vector quantity that is described by both magnitude and direction. Forces cause an object to accelerate.

Therefore, The force of gravity between two objects is proportional to the product of their masses and inversely proportional to the square of the distance between them. So if one of the objects has its mass halved, the gravitational force between them will decrease by a factor of (1/2)^2 = 1/4.

So the diver's velocity when her feet strike the water is 1.37 m/s.

Velocity is a vector representation of an object's or particle's displacement with respect to time. The meter per second (m/s) is the standard unit of velocity magnitude (also known as speed). Alternatively, velocity magnitude can be expressed in centimeters per second (cm/s).

Here,

(a) To find the diver's highest point above the board, we can use the conservation of energy principle. The initial potential energy of the diver at the takeoff point is given by

PEi = mgh

where m is the mass of the diver, g is the acceleration due to gravity (9.8 m/s² ), and h is the height of the takeoff point (1.80 m). The final potential energy of the diver at the highest point is zero, since she is at her maximum height and has no potential energy. The initial kinetic energy of the diver at the takeoff point is given by

KEi = 0.5 * m * v²

where v is the initial velocity of the diver (4.00 m/s). The final kinetic energy of the diver at the highest point is also zero, since she has no velocity at that point.

The total mechanical energy of the system (the diver) is conserved, so the initial potential and kinetic energies are equal to the final potential and kinetic energies:

PEi + KEi = PEf + KEf

Substituting the expressions for the initial and final potential and kinetic energies, we have

mgh + 0.5 * m * v²  = 0

Solving for h, the height of the highest point above the board, we have

h = v²  / (2g) + h

h = 4.00²  / (2 * 9.8) + 1.80 = 2.63 m

So the diver's highest point above the board is 2.63 m.

(b) To find the time that the diver's feet are in the air, we can use the kinematic equation for vertical motion with constant acceleration:

y = y0 + v0 * t + 0.5 * a * t²

where y0 is the initial height of the diver's feet (1.80 m), v0 is the initial upward velocity of the diver (4.00 m/s), a is the acceleration due to gravity (9.8 m/s² ), and t is the time in the air.

We can find the final height of the diver's feet when they hit the water by setting y = 0 and solving for t:

0 = 1.80 + 4.00 * t - 4.9 * t²

t = √(4 * 1.80 / 4.9) = 0.81 s

So the time that the diver's feet are in the air is 0.81 s.

(c) To find the velocity of the diver when her feet hit the water, we can use the kinematic equation for vertical motion with constant acceleration:

v = v0 + a * t

where v0 is the initial upward velocity of the diver (4.00 m/s), a is the acceleration due to gravity (9.8 m/s² ), and t is the time in the air (0.81 s).

v = 4.00 - 9.8 * 0.81 = 1.37 m/s

So the velocity of the diver when her feet hit the water is 1.37 m/s.

The force exerted on the surface assuming that it bring the electron to rest  is -6.1 * 10^-16 N

The force exerted on the surface can be determined using the equation below:

Force = (incident current) * (change in kinetic energy) / (change in time)

The change in kinetic energy of each electron can be calculated as:

ΔKE = (1/2) * (mass of electron) * (final velocity^2 - initial velocity^2)

Since the electrons come to rest, the final velocity is 0. Hence the initial velocity can be calculated using the equation:

initial velocity = (2 * potential difference) / mass of electron

Therefore we calculate ΔKE and then find the force:

mass of electron = 9.1 * 10^-31 kg

potential difference = 5 kV = 5 * 10^3 V

time = 5 s

incident current = 50 * 10^-6 A

initial velocity = (2 * potential difference) / mass of electron = (2 * 5 * 10^3) / (9.1 * 10^-31) = 1.1 * 10^8 m/s

ΔKE = (1/2) * (mass of electron) * (0^2 - (1.1 * 10^8)^2) = -6.1 * 10^-19 J

Force = (incident current) * (ΔKE) / (time) = (50 * 10^-6) * (-6.1 * 10^-19) / (5) = -6.1 * 10^-16 N

To the left = 918.5 N

To the right = 845.3 N

The climber is not moving, hence there is no acceleration, and because the defined angles are not in the typical direction, sin rather than cos is actually required for the horizontal.

Fx = T right x - T left x = max = 0

T right x = T right sin (80.0⁰) = T left sin (65.0⁰) = T right left

T left = T right {sin (80.0⁰) / sin (65.0⁰)}

T right Y + T left Y = T right cos 80.0⁰ + T left cos 65.0⁰ = W

T right = 535 N / 0.6329

The magnitude of the charge on each sphere is 7.22nC when two small metallic spheres each with a mass of 0.20 g pendulums equilibrium 30.0 cm.

Given the mass of each metallic sphere (m) = 0.20g = 20 x 10^-3kg

The length of the spring is (L) = 30cm = 30 x 10^-2m

The charge on two spheres is same = q

The angle of equilibrium = 5°

A force acting in the same direction as the string is called tension.

Let's denote the horizontal component as = Fx and

the vertical component as = Fy then the magnitude of tension is:

T = √Fx^2 + Fy^2

We can observe that the weight of gravity is the only other vertical force acting on mass. W = ma where a is acceleration due to gravity= -9.8m/s^2 Fy and W are equal because we are in equilibrium (mass is fixed and does not change position) (equal magnitude, opposite directions).

Fy = 20 x 10^-3 x 9.8 = 196 x 10^-3N

We can write utilizing the angle of the string as:

Fy = Tcos(5°)

Fx = Tsin(5°)

We know that electric force (Fe) = kq1q2/r^2 = 0.00197 * sin5

196 x 10^-3 * sin5 = 9 * 10^9 * q^2 / (0.3*(sin5)*2)^2)

An ellipse is a type of conic section, a curve that results from the intersection of a cone and a plane. It is defined as a set of points such that the sum of the distances from two fixed points (called foci) to any point on the curve is constant. An ellipse has two axes: the major axis, which is the longest and the minor axis, which is the shortest. The foci lie on the major axis and the length of the major axis is twice the distance between the foci.

The shape of the ellipse is determined by the ratio of the lengths of the two axes, called the eccentricity. When the two axes are equal, the ellipse is a circle. Ellipses appear in many natural and man-made objects, including planetary orbits and the shapes of car headlights, bottle bottoms and egg yolks.

[tex]$$\left|\dfrac{a-b}{1-\overline{a}b}\right| = \frac{|a - b|}{|1 - \overline{a} b|} = \frac{2 \sin \left(\frac{1}{2} \angle (b - a)\right)}{2 \sin \left(\frac{1}{2} (\angle (a) - \angle (b))\right)}$$[/tex]

Since the sine function is always between -1 and 1,

So, we can again write it as:

[tex]$$\left|\dfrac{a-b}{1-\overline{a}b}\right| \leq \frac{1}{1} = 1$$[/tex]

However, we can see that this maximum value is achieved when a and b are diametrically opposed on the unit circle,

so

[tex]$$\left|\dfrac{a-b}{1-\overline{a}b}\right| = \frac{2}{2} = 2$$[/tex]
