A12kg turtle rests on the bed of a zookeeper's truck, which is traveling down a country road at 55mi/h. the zookeeper spots a deer in the road, and slows to a stop in 12s. assuming constant acceleration, what is the minimum coefficient of static friction between the turtle and truck bed surface that is needed to prevent the turtle from sliding?

The passing of heat through a material while the material itself stays in place. a. radiation b. conduction c. convection

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.

Apositive charge moves in the direction of an electric field. which of the following statements are true? check all that apply. check all that apply. 1.the potential energy associated with the charge decreases. 2. the electric field does positive work on the charge. 3. the electric field does negative work on the charge. 4. the potential energy associated with the charge increases. 5. the electric field does not do any work on the charge. 6. the amount of work done on the charge cannot be determined without additional information.
