Academics

Q. A 125-g steel ball with a kinetic energy of 0.25J rolls along a horizontal track. How high up an inclined track will the ball roll if friction can be ignored.

Q. How much energy must be added to a bowl of 125 popcorn kernels in order for them to reach a popping temperature of 175celsious? assume that their initial temperature is 21 celsious, that the specific heat capacity of popcorn is 1650 j/kgcelsious, and that each kernel has a mas of 0.105g.
