Two objects were lifted by a machine. One object had a mass of 2 kg and was lifted at a speed of 2 m/s. The other object had a mass of 4 kg and was lifted at a rate of 3 m/s. Which object had more kinetic energy while it was being lifted? Which object had more potential energy when it was lifted to a distance of 10 m?

waves moving from a fast medium to a slow medium will experience a reflection as light travels more slowly than red light. total internal reflection occurs when the critical angle is.

this is an example of "committed" time.

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?
