7. In outer space, two astronauts sit at rest next to each other. Bruno, the larger astronaut whose mass is 100 kg, is twice as massive as Timmy, the smaller astronaut. If Bruno pushes
Timmy with a force of 100N, how far apart will they be in 2 seconds?

The speed of sound in ice, water, and steam is shown. what best explains the speed of sound in different states of matter? sound travels fastest in ice because energy is easier to transfer when the molecules are close together. sound travels slowest in steam because the sound has to move around the gas molecules that are far apart. sound travels fastest in ice because the temperature of solids is always greater, so the heat transfers the sound energy. sound travels slowest in steam because the pressure is so great the sound cannot travel though the steam particles.

What is the equation for electrical work?
