Consider two spaceships moving relative to each other. The relative velocity of each spaceship is the velocity the other spaceship sees it moving at. Both relative velocities are equal in magnitude (equal speeds) but opposite in direction.

Required:
If one spaceship fires a missile at 0.745c at the other spaceship as it approaches and the other spaceship observes the missile approaching it at 0.93c. What is the ratio of the first spaceship's relative velocity to the speed of the light.

In positive numbers less than 1, the zeros between the decimal point and non zero are significant

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.

The ability to make things happen is also called a. heat b. force c. matter d. energy
