A rectangular object measures 3 cm x 2 cm x 1 cm and it has a mass of 4 g. What is the density of this rectangular object?

Density of the rectangular object = 4 / 6 = 0.67g/cm³

Explanation:

First find the volume of the rectangular object.

Volume of the rectangular object = 3 x 2 x 1 = 6cm³.

Density of an object = mass of the object / volume of the object

Therefore,

Density of the rectangular object = 4 / 6 = 0.67g/cm³

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.
