the mass if an element is .007502 x 10^-26 g. find the Number of significant figures when the mass is converted to mg. (both masses values have same order of magnitude)

d. 4.

Explanation:

Hello,

In this case, the required number on milligrams is:

It means that it has four significant figures which are counted for 7, 5, 0 and 2, considering that zero as it is to the right of first nonzero digit (7).

Regards.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
