The answer to the first question is that plants make glucose and oxygen by taking in CO2 and H20.
The answer to the second question is having a heavier mass increases the force of a moving object. That is the Second Law of Motion, F = ma.
Heat makes things expand, so in hot water the ballon will get bigger
This means that two objects will reach the ground at the same time if they are dropped simultaneously from the same height. ... When air resistance plays a role, the shape of the object becomes important. In air, a feather and a ball do not fall at the same rate.
Kinetic energy is directly proportional to the square of their velocities... so if velocity has been increased 3 times, increase in K.E would be: 3^2 = 9
In short, Your Answer would be: KE2 = 9 * KE1
Hope this helps!
