What does this image reveal about gravityon the moon compared to Earth?
elena-14-01-66 [18.8K]

ANSWER:

The Moon's gravity is less than Earth's.

STEP-BY-STEP EXPLANATION:

When you jump, you fall back to the ground. Apples or leaves also fall: we are all attracted to the Earth. It is the terrestrial attraction due to the force of gravity.

The force of gravity also exists on the Moon. But since the Moon is smaller than the Earth, the attraction felt on the Moon is smaller than the Earth's attraction.

As the gravity is less, you can do things such as the one shown in the image.

As the force of attraction is less, the weight is less on the Moon, which can cause things that would be impossible on Earth.

Technician A says that in a series circuit, if one light goes out, the rest of the lights stay on. Technician B says that in a p
vivado [14]

Answer:

Explanation:

Technician A is incorrect as in series circuit the current is the same for all the resistors and if one bulb fails in the path then the circuit is incomplete and therefore no flow of current.

Technician B is correct as in parallel circuit there are multiple paths for current through which it can pass and malfunctioning of one resistor does not affect the other.

A hot-air balloon is ascending at the rate of 12 m/s and is 80 m above the ground when a package is dropped over the side. (a) H
Debora [2.8K]

Answer:

Explanation:

Given

balloon is ascending at the rate of u=12\ m/s

Balloon is at a height of s=80\ m

As the package is dropped from the balloon it must possess the same initial velocity as the balloon

using

v^2-u^2=2as  

where v=final velocity

u=initial velocity

a=acceleration

s=displacement

v^2=12^2+2\times 9.8\times 80

v^2=1712

v=41.37\ m/s

time taken is  given by

v=u+at

substituting values

41.37=-12+9.8\times t

as we consider downward direction as positive

t=\frac{53.37}{9.8}

t=5.44\ s

therefore time taken to reach the bottom is t=5.44 s

Which of these objects must have the greatest force acting on it? pls help fast
8_murik_8 [283]

Let's look at Newton's second law

  • F=ma

Force is directly proportional towards mass

If mass is more force will be more.

Between baseball and bowling ball Bowling ball has higher mass

So it would expert most force

Option D
