The first attempt at publishing a list of relative atomic masses was made by

Where F is the magnitude of the gravitational attraction on either body, m1 and m2 are the masses of the bodies, r is the distance between them, and G is the gravitational constant.

Will an object with a density of 1.05 float or sink? Explain.

Momentum can be defined as "mass inmotion." All objects have mass; so if anobject is moving, then it has momentum - ithas its mass in motion.

Hot air enters a rectangular duct (20cm wide, 25cm high, and 5m long) at 100 kPa and 60 degrees C at an average velocity of 5 m/s. While air flows the duct, it gets cool down (loses energy) so that air leave the duct at 54 degrees C.

A child pulls a balloon for 12 m with a force of 1.0 N at an angle 60° below horizontal. How much work does the child do on the balloon?
