I added individual steps for clarity. Note that g must be positive if the solution is to be real.
Let me know if you have any questions.
Kinetic energy is energy that a body possesses by virtue of being in motion, there for if an object is moving, it has kinetic energy.
Example; A roller coaster sitting on top of hill has potential energy. When it starts to move and is going down the hill, it has kinetic energy. :)
Answer:
that one i know only pe not that sorry again
find acceleration force divided by Mass
a=f/m
According to your formula, because Th>Tc, the density of hot air greater than the density of cold air.<span>Hint: You can rearrange the ideal gas law to get </span>
