Which two components must a vector quantity have?
a. Magnitude and velocity
b. Acceleration and direction
c. Force and speed
d. Direction and magnitude

Light from the sun reaches the earth in 8.3 minutes. the velocity is 3.00 x 10^8 m/s. how far is earth from the sun? i know how to get to d = (3 x 10^8 m/s)(498 sec). i just don't know how to get from there to the answer being 1.5 x 10^11 m.

Determine el momento angular de un rueda de 3000g moviendose a 10m/s con un radio de giro de 400cm

Steam enters an adiabatic diffuser at 150 kpa and 1208c with a velocity of 550 m/s. determine the minimum velocity that the steam can have at the outlet when the outlet pressure is 300 kpa.
