<span>A. Scientists want to share measurement data that they can understand.</span>
Are there answer choices or do you just need an answer?
The answer is D: test possible choices and then avoid ones that are not desirable.
Answer:
D
Explanation:
The vehicles have the same amount of kinetic energy because they are travelling at the same speed. There is a great difference in their masses but their speed is same. Kinetic energy of a body depends on both mass and velocity. If the mass of an object increases, its kinetic energy also increases and vice versa while on the other hand, if we doubles the speed of an object its kinetic energy increases four times so we can conclude that objects having same speed leads to same kinetic energy.
A scale is used to measure mass in grams. ☺♥
