Aspacecraft is launched from the surface of the earth with a velocity of 0.600c at an angle of 50.0 above the horizontal, positive x-axis. another spacecraft is moving past with a velocity of 0.700c in the negative x direction. determine the magnitude and direction of the velocity of the first spacecraft

a) electrical > light, sound, and thermal< < < <

) the mechanical energy of the firefighter moving.< < < < a) electrical > light, sound, and thermal< < < <

c) both a and b.

layers of the earth affect the waves and these effects are seen on instruiments such as seimometers
