Why must a scientist use standard units of measure in experience and work

Scientist accept ideas of the past and do not try to revise or change them

A Van de Graaff generator is one of the original particle accelerators and can be used to accelerate charged particles like protons or electrons. You may have seen it used to make human hair stand on end or produce large sparks.

How far will an object move in 3 s if its average speed during that time is 40 m/s? Answer in units of m.

A transfer by work from the system, an elevation decrease of 50 m, and an increase in velocity from 15 m/s to 30 m/s. The specific internal energy, u, decreases by 5 kJ/kg and the acceleration of gravity is constant at 9.7 m/s².

What is the best prediction for the weather on the day after high pressure system passes

Is it possible to have motion in the absence of a net force?

There are 2 charged particles, A and B. You know that particle A is positively charged. When you place particle B next to particle A, then particle B starts moving away from particle A. What does this mean for particle B?

The speed of light is now to be defined 2.99792458x10^8 m/s express the speed of light to three significant figures five significant figures seven significant figures
