The diameter of our disk-shaped galaxy, the milky way, is about 1.0 x 10^5 light-years (ly). the distance to the andromeda galaxy, which is the spiral galaxy nearest to the milky way, is about 2.0 million ly. if a scale model represents the milky way and andromeda galaxies as dinner plates 25 cm in diameter, determine the distance between the centers of the two plates.

Using the work energy theorem. what is the velocity of a 850kg car after starting at rest when 13,000j of work is done to it.

If forces acting on an object are unbalanced. true or false

Amachinist turns the power on to a grinding wheel, at rest, at time t = 0 s. the wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 96 rad/s. the wheel is run at that angular velocity for 40 s and then power is shut off. the wheel slows down uniformly at 1.5 rad/s2 until the wheel stops. in this situation, the time interval of deceleration is closest to:
