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: the correct answer id option(d).

explanation:

snell's law refraction:

the angle of refraction =

the angle of incidence =

refractive index of air = = 1

refractive index of glycerol = 1.47

from the given options, the most closest answer to 63.72° is 65° of option (d).

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
