The unit of measure that is the same for all systems of measure is the: a. calorie
b. kilogram
c. meter
d. pound
e. second

Second

Explanation:

There are three types of fundamental units :

1. C.G.S system  : Centimeter, gram and second

2. M.K.S. system  : meter, kilogram and second

3. F.P.S. system  : foot, pound and second

4. Finally S.I. units : like Newton, Joule etc.

In all type of units time is measured in seconds. It remains the same. So, the unit of measure that is the same for all systems of measure is the second. Hence, this is the required solution.

answer: point c: b. 1/2 potential, 1/2 kinetic, point a: 3/4 of its potential energy, point d or b: 3/4 potential, 1/4 kinetic

explanation: i cant explain. it's difficult to explain.
