Answer: Given the evidence in the explanation, I'm pretty sure it's C. It still exists, but in a different form.
Explanation: "Some part of the energy supplied is used to change the internal energy of the system. Some part is also released into the surroundings. Generally, frictional losses are more predominant for the machines being not 100% efficient. This friction leads to the loss of energy in the form of heat, into the surroundings."
The second Newton's law of motion states that the rate of change in momentum of a moving body is proportional to the resultant force.
Therefore, to understand this law one must understand the concept of momentum and that a body in motion experiences force.
As far as momentum is concerned it is important to note that as a body moves the momentum changes with change in time and also that a body at rest has 0 momentum because its speed/velocity is zero.
It is this change in momentum with time that is proportional to the resultant force experienced by the body.
Answer:
Cloud is a condensed from of atmospheric moisture consisting of small water droplets.
Clouds cause rainfall and snow fall.
Different types of clouds are found in the atmosphere. Some main types of them are cirrus, cumulus, nimbus, and stratus. Most clouds are generated by the cooling of air as it rises.
Increasing the pressure of gas is like exactly the same as increasing its concentration. If you have a given mass of gas, the way you increase its pressure is to squeeze it into a smaller volume.
Hope this helps!
