Please answer questions as soon as possible. Will be picking the brainiest answer.

1. One is more compact than the next hence more density

2. A: 0.67g/cm3 hence will sink

B:0.56g/cm3 hence will sink

C:0.91g/cm3 hence will sink

Explanation:

Use the formula mass/volume to find its density with S.I unit is g/cm3

And to determine weather or not it sink use the relative density formula

Density of substance / Density of water

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.
