d. there is no air in the moon so objects her lighter

Determine the maximum r-value of the polar equation r =3+3 cos 0

Name the non metal condut electricity

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 · s2). use g = 9.80 m/s2 and calculate the mass m of the ball.
