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.

The experiment done in lab is repeated, using a ball that has unknown mass m. you plot your data in the form of f 2 versus m/l, with f in rev/s, m in kg, and l in m. your data falls close to a straight line that has slope 3.19 m/(kg Β· s2). use g = 9.80 m/s2 and calculate the mass m of the ball.

Orque can be calculated by multiplying the force (n) applied at 90β to the lever arm at a distance (m) from the pivot point (point of rotation), the compound si unit for the torque is nβ
m. if the force (at 90β to the lever arm) applied is 15 n and it is applied at 2.0 m from the pivot point (point of rotation), what is the torque on the lever?
