You drop a marble ball into a glass filled with water, which results ib 3.75 ml of water being displaced (spilled out). given that the mass of the marble ball is 9.513g, what is the density of that marble ball?

- Density is 2.54 gram per mL.

Solution:-

Mass of the marble ball is given as 9.513 g and it's volume is 3.75 mL.

To calculate the density of the marble ball let's plug in the values in the formula:

So, the density of the marble ball is 2.54 gram per mL.

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.
