insulating spheres a and b are initially neutral and touching. a positively charged rod is brought near a, but not touching. the spheres are separated, and then the rod is taken away. describe the resulting net charge of each sphere.

Answers

Answer 1

The electrons in the spheres pull away from the rod's electrons and gather to the right. As a result, the left sphere begins to accrue a positive charge.

The rod and the two spheres are then separated. The left sphere finally reaches positive charge, while the right sphere reaches negative charge.

What distinguishes a conducting sphere from an insulating sphere?

A charge is carried by an insulating sphere and is distributed evenly across its volume. The charge on a conducting sphere of the same size is the same, but it is only distributed across its surface (as it must for a conductor.)

a satellite is placed in an orbit with a radius that is half the radius of the moon's orbit. find its period in units of the period of the moon.

Answers

The period of a satellite in an orbit around the Earth with a radius half that of the moon's orbit is 0.35 TM. Thus, Option A is correct.

Based on the answer, we understand that it takes 0.35 times the amount of time for the satellite to complete one full orbit as it takes for the moon to complete one orbit around the Earth.

To explain, the period of a satellite in orbit around the Earth is directly proportional to the square root of the semi-major axis of its orbit. Since the semi-major axis of the satellite's orbit is half that of the moon's orbit, the square root of this value will also be half the square root of the moon's orbit, resulting in a period that is 0.35 times that of the moon's orbit.

Kepler's third law states that the square of the orbital period of a planet or satellite is proportional to the cube of the semi-major axis of its orbit, so a satellite with a smaller semi-major axis will have a shorter period.

what is the length of a pendulum whose period on the moon matches the period of a 1.4- m -long pendulum on the earth?

Answers

Length of a pendulum whose period on the Moon matches the period of a 1.4 m pendulum on the Earth is approximately 0.23 m.

What is period of pendulum?

The time taken by the pendulum to finish one full oscillation is called time period of a simple pendulum.

The period of a pendulum is : T = 2π√(l/g), where T is period, l is length of the pendulum, and g is acceleration due to gravity. On the Moon,  acceleration due to gravity is approximately 1/6 of that on the Earth, or g_moon = 1.62 m/s².

Let length of  pendulum on the Moon be l_moon. Period of the pendulum on the Moon is T_moon = 2π√(l_moon/g_moon). Setting T_moon equal to the period of the 1.4 m pendulum on the Earth, T_earth = 2π√(1.4 m / 9.8 m/s²), we can find the length of the pendulum on the Moon:

T_moon = T_earth

2π√(l_moon / 1.62 m/s²) = 2π√(1.4 m / 9.8 m/s²)

Solving for l_moon, we find:

l_moon = (1.4 m) * (1.62 m/s²) / (9.8 m/s²) = 0.23 m

So the length of a pendulum whose period on the Moon matches the period of a 1.4 m pendulum on the Earth is approximately 0.23 m.

Answers

The initial speed of the egg is calculated to be approximately 29.6 m/s.

What is speed?

Rate of change of position of any object in any direction is called speed.

We use following kinematic equation to find initial velocity of the egg:

where h is initial height of the egg, vi is initial velocity, t is time elapsed, and g is acceleration due to gravity (9.8 m/s²).

So, h = vi * t + (1/2) * g * t²

30.0 m = vi * 5.00 s + (1/2) * 9.8 m/s² * 5.00 s²

vi = 2 * (30.0 m - (1/2) * 9.8 m/s² * 5.00 s²) / 5.00 s = 29.6 m/s

Answers

The plane will travel a distance of 2175 meters while its velocity is changing from 145 m/s to 75 m/s at a uniform rate of acceleration.

What is a change in acceleration?

The rate at which velocity changes in relation to time is known as acceleration. It is a vector quantity that gauges the magnitude and direction of a change in velocity. It can be calculated as the velocity's time-dependent derivative or as the velocity change divided by the time-dependent change. The metric for acceleration is meters per second squared (m/).

The difference between two levels of acceleration, either at different times or in distinct directions, is referred to as a change in acceleration. According to mathematics, it can be described as the difference between final acceleration and initial acceleration, as shown by the equation:

Δa = a2 - a1

where "a" stands for the acceleration change, "a2" for the final acceleration, and "a1" for the starting acceleration.

distance = (initial velocity x time) + (1/2) x acceleration x

acceleration = (final velocity - initial velocity) / time

we get:

acceleration = (75 - 145) / 15 = -5 m/

Now,

distance = (145 x 15) + (1/2) x (-5) x  = 2175 m

Therefore, the plane will travel a distance of 2175 meters.

if 5.4 j of work is needed to stretch a spring from 10 cm to 16 cm and another 9 j is needed to stretch it from 16 cm to 22 cm, what is the natural length (in cm) of the spring?

Answers

The required natural length of the spring is 0 cm.

How we get the natural length of the spring?

The work done on a spring is given by the equation W = (1/2)kx^2, where W is the work done, k is the spring constant, and x is the change in length of the spring.

From the information given:

we have two equations:

W1 = (1/2)k(16-10)^2 = 5.4 J

W2 = (1/2)k(22-16)^2 = 9 J

Solving for k, we can find the spring constant:

k = (2W1)/(16-10)^2 = (2 * 5.4) / (16-10)^2 = 2.7 / 36 = (2.7 / 12^2) N/m

Next, we can use the spring constant to find the natural length (the length of the spring when no force is applied) by setting x = 0 in the equation for work:

W = (1/2)kx^2 = (1/2)k * 0^2 = 0 J

So, x = (2W / k)^(1/2) = (2 * 0 / (2.7 / 12^2))^(1/2) = 0 cm

This means that the natural length of the spring is 0 cm. Note that the unit cm is not used in the calculation of the spring constant, and that the spring constant has units of N/m.

the space shuttle travels at a speed of about 6.38 x 103 m/s. the blink of an astronaut's eye lasts about 116 ms. how many football fields (length

Answers

Using speed, distance, time relation, The Space Shuttle covers approximately 8 football fields in the blink of an astronaut's eye.

How do you determine speed?

The speed of something or someone is how swiftly they are moving. You can determine something's average speed if you know how far it has traveled and how long it took to get there. Speed is determined by the formula: speed = distance time. Calculating the units for speed requires knowledge of the units for both time and distance.

The equation speed = distance time can be altered, just like any other equation.

The formula can be set up in one of three ways:

Distance is determined by time and speed.

Time and speed both affect distance.

Time = Speed x Distance

To compute one of the variables, we require the other two (speed, distance, or time).

For instance, we need to know the distance traveled and the speed at which movement occurs in order to calculate the travel time.

To find out how many football fields the shuttle covers in one blink of an eye, we need to divide the distance it travels in 116 ms by the length of one football field.

First, let's find the distance:

distance = speed x time

distance = 6.38 ×  m/s × 116 ms

distance = 738.88 m

Next, let's divide the distance by the length of a football field:

distance ÷ length of a football field

738.88 m ÷ 91.4 m  = 8.09 football fields

So the Space Shuttle covers approximately 8 football fields in the blink of an astronaut's eye.

The final velocity of the two clay models after they stick together is 0.545 m/s.

The final velocity of the two clay models after they stick together can be calculated using the conservation of momentum principle, which states that the total momentum of an isolated system remains constant if no external forces act on it. The initial momentum of the system is the momentum of the first clay model and the final momentum is the momentum of the two clay models combined.

The momentum of each clay model can be calculated using the formula:

p = m * v,

where p is momentum, m is mass, and v is velocity.

The initial momentum of the first clay model:

p1 = m1 * v1 = 0.190 kg * 0.610 m/s = 0.116 kg * m/s

Final momentum of the combined clay models:

p_final = (m1 + m2) * v_final = (0.190 kg + 0.310 kg) * v_final

Equating the initial momentum to the final momentum and solving for v_final:

v_final = p1 / (m1 + m2) = 0.116 kg * m/s / (0.190 kg + 0.310 kg) = 0.545 m/s

So the final velocity of the two clay models after they stick together is 0.545 m/s.

the abs system prevents the wheels from locking or skidding, no matter how hard the brakes are applied or how slippery the road surface. group of answer choices true false

Answers

It is true that the Anti-Lock Braking System (ABS) helps prevent the wheels from locking or skidding when the brakes are applied, even on slippery road surfaces.

What is friction?

Friction is the force that prevents solid surfaces, fluid layers, and material components from sliding against each other. There are several kinds of friction: Dry friction is the force that opposes the relative lateral motion of two in touch solid surfaces. Friction is the force that prevents one solid item from slipping or rolling over another. Frictional forces, such as the traction required to walk without slipping, are advantageous, but they also create a significant amount of resistance to motion. We can manage automobiles because of friction between the tires and the road: more precisely, because there are three types of friction: rolling friction, beginning friction, and sliding friction.

Here,

ABS maintains tire traction and steerability by swiftly applying and releasing the brakes, which enhances braking performance and assists the driver in maintaining vehicle control.
