What are two variables that affect kinetic energy

The answer for the following questions is explained below.

Explanation:

The two variables that affect kinetic energy are:

The kinetic energy of an object depends on both its mass and its velocity

Kinetic energy increases as mass increases

For example,think about rolling a bowling ball and a golf ball down a bowling lane at same velocity

Here,the bowling ball has more mass than the golf ball

Therefore you use more energy to roll the bowling ball than to roll the golf ball

The bowling ball is more likely to knock down the pins because it has more kinetic energy than the golf ball

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.
