Consider the double pulley system in the figure, with two hanging two masses, where M1 = 56 kg and M2 = 1.5 kg. The string has a mass density of ρ = 55 g/m which is much smaller than either of the hanging masses, and there is no friction in the pulleys.

Determine the age of a fossil if it had only one eighth of its original carbon-14 content remaining?

Which accounts for an increase in the temperature of a gas that is kept a constant volume

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.
