Answer:
Explanation:
force = f, mass = m, acceleration = a
f = m a
m = 200 kg
f = 800 N
f = m a
800 = 200a
a = 800 / 200
<u><em>a = 4</em></u>
Hope this helps
plz mark as brainliest!!!!!!!
The reason the efficiency is always less than 100% is because there is always some sort of friction in the machine.
Answer: because of friction
If you read the question carefully, you can find the answer right there in it.
In fact, you don't even have to read the whole question ... you only need to read one word.
In fact, you don't even have to read the whole word ... you only need to read part of the word.
The word to read is "wavelength".
The important part of the word is "length".
<em>Now</em> it's time to look at the picture:
#1 is a height.
#2 is a place on the wave
#4 is a place on the wave
<em>#3 </em>is the only thing in the picture that's a "length" of anything.
Answer:
So as the mass of either object increases, the force of gravitational attraction between them also increases. If the mass of one of the objects is doubled, then the force of gravity between them is doubled. If the mass of one of the objects is tripled, then the force of gravity between them is tripled.
