Momentums equation is just p=mv
mass times velocity so 50x200
p=10,000
If you decrease the pressure of a fixed amount of gas, its volume will increase.
Mechanical energy is the energy that is possessed by an object due to its motion or due to its position. It can either be kinetics or potential. In this problem you know it starting position so you can calculate it's potential energy (PE):
<span>PE=mass∗gravity∗height=0.3kg∗9.8m/s2∗1.8m=?
</span>The answer will typically be given in joules:
1J=kg∗m2s2 Could be wrong... But I believe it is 5.3...? as a final product.
The answer is as voltage increases current increases and therefore resistance would remain constant
