If an atomic bomb were detonated on the surface of the moon, how long would it be until we heard the explosion on Earth?

<h2>Answer: </h2>

The detonation would not be heard on Earth, therefore we would wait infinitely for it.

This is because the sound is a mechanical wave, whose main characteristic is that it necessarily needs a medium to propagate; unlike electromagnetic waves that can propagate in vacuum.

After knowing this, we add the fact that the space that separates the Earth and the Moon is the vacuum, therefore, if an atomic bomb were detonated on the surface of the moon, this would not be heard on Earth.

What is the magnitude of velocity for a 2000 kg car possessing 3000 kgm/s of momentum
Alex

For this case we have that by definition, the momentum is given by:

p = mv

Where,

  • <em>m: mass </em>
  • <em>v: speed </em>

Therefore, replacing values we have:

3000 = (2000) v

From here, we clear the value of the speed:

v = \frac {3000} {2000}\\v = 1.5 \frac {m} {s}

Answer:

The magnitude of velocity is:

v = 1.5 \frac {m} {s}

The ice skaters partner liftes her up a distance of 1 m work done or not work done
SOVA2 [1]

Answer:

Work done.

Explanation:

The skater who lifts has to overcome the partner's weight. When lifted up by 1 meter, her potential energy increases by (mass)x(gravitational acceleration)x(1meter), which is the amount of work done.

(This all assumes lifting vertically and no other forces being part of the picture)

a parking lot is going to be 60m wide and 240m long which dimensions could be used please please help
Bezzdna [24]

Answer: The area of the parking lot is 14,400 meters squared.

Explanation:

We have the dimensions of the parking lot.

60m by 240m

The units used here are meters.

Now, if we want to know the area of the parking lot is equal to the product between the length and the width:

A = 60m*240m = 14,400 m^2

The area of the parking lot is 14,400 meters squared.
