We have to find the height of the shelf
We know that,
Putting the values,
<h3>The height of the shelf is 1.76 m </h3>
Answer:
nanometer, micrometer, centimeter, meter, kilometer
Answer:
20000 kg*m/s
Explanation:
Momentum is equal to mass * velocity. So plug in 1000 kg and 20 m/s for mass and velocity respectively to get 1000*20 = 20000. Be sure you convert to the correct unit when doing future problems
It is true that cows, grain, and land were
more difficult to move from place to place
<span>Coins were developed as a medium of exchange
because they are easy and more convenient in negotiating and purchasing. For

country to another country.</span>
"Mass" is the amount of matter that makes up your body. It doesn't depend on where you happen to be, any more than the amount of money in your pocket depends on where you are. If your mass is 65 kg in your kitchen, then it's 65 kg. Doesn't matter whether you're in the basement, in school, at the bottom of the ocean, in Mexico, in China, anywhere else on Earth, anywhere on the moon, or floating in space.
