Ahollow cylinder of mass m and radius r rolls down an inclined plane. a block of mass m
easily slides down an identical inclined plane. complete the following statement: if both
objects are released at the same time from the top of their inclined planes,
a) the cylinder will reach the bottom first.
b) the block will reach the bottom first.
c) the block will reach the bottom with the greater kinetic energy.
d) the cylinder will reach the bottom with the greater kinetic energy.
e) both the block and the cylinder will reach the bottom at the same time.

In positive numbers less than 1, the zeros between the decimal point and a non-zero number are blank significant

The speed of sound in ice, water, and steam is shown. what best explains the speed of sound in different states of matter? sound travels fastest in ice because energy is easier to transfer when the molecules are close together. sound travels slowest in steam because the sound has to move around the gas molecules that are far apart. sound travels fastest in ice because the temperature of solids is always greater, so the heat transfers the sound energy. sound travels slowest in steam because the pressure is so great the sound cannot travel though the steam particles.

Which of these is not a possible type of energy transformation? a. electrical energy into light energy b. sound energy into nuclear energy c. potential energy into kinetic energy d. kinetic energy into mechanical energy
