Kinetic energy is proportional to the square of the speed. So when anything or anybody speeds up, its kinetic energy increases.
C standards are based on observable, reproducible natural phenomena.
Answer:
<em>The cantaloupe has a speed of 117.6 m/s</em>
Explanation:
<u>Free Fall Motion</u>
It occurs when an object falls under the sole influence of gravity. Any object that is being acted upon solely by the force of gravity is said to be in a state of free fall. Free-falling objects do not face air resistance.
If an object is dropped from rest in a free-falling motion, it falls with a constant acceleration called the acceleration of gravity, which value is
.
The final velocity of a free-falling object after a time t is given by:
vf=g.t
The cantaloupe has been dropped from rest. We are required to find the speed after t=12 seconds.
Calculate the final speed:
vf=9.8 * 12 = 117.6 m/s
The cantaloupe has a speed of 117.6 m/s
The answer is A. it is the flow of electric charge. Current in electric circuits is carried by moving electrons in a wire. The current can also be carried by ions in electrolyte. Ampere is the SI unit for measuring an electric current. The electric current is measured using an equipment called ammeter.
