"Constant velocity" means zero acceleration, which means zero net force. So there must be100N pulling on the crate to cancel the 100N of friction force.
Answer:
Third law
Explanation:
cause it has to do with the reaction of the balloon
Hope this right!
Answer:
The final speed of the rocket once the engine has fired is 29.16 m/s.
Explanation:
By the principle of momentum and amount of movement, we match the momentum data to the amount of movement and find the value of speed.
I=3.5 kg*m/s
m=120g= 0.12kg
V=?
I=F*t
F*t=m*V
I/m=V
(3.5 kg*m/s) / 0.12kg = V
V=29.16 m/s
Hello!!
For this, we only need frequency and speed, so for calculate we applicate formula:
The correct answer is that water, as it rises in the atmosphere, condenses and forms clouds - the correct answer is b.
Other options are false, for example:
a. It evaporates.
-this is the beginning of the process: water needs to evaporate to be in the atmosphere - so it's before the process that the question addresses
Also it is not used up: otherwise Earth would run out of water.
