An object with mass m moving in a circle of radius r with speed v has linear momentum of magnitude mv and an angular momentum of magnitude mvr. is it dimensionally possible to add the magnitudes of linear momentum and angular momentum?
a).yes, since both quantities have the same dimensions.
b).no, since the quantities have different dimensions.
c).yes, since both quantities include mass.

We put a force of 50n on an object and the acceleration is 100 m/s². what is the mass of the object?

The magnitude of the amount of energy released by burning a fuel source, measured in energy per unit mass, is called its fuel value. note that the fuel value is the negative of the isobaric specific heat of combustion for the fuel. if all the energy obtained from burning 1.23 pounds of butane with a fuel value of 10.85 kcal/g is used to heat 128.0 kg of water at an initial temperature of 18.3 °c, what is the final temperature? note that 1 lb = 453.6 g.
