Question 8 [1 point) You tryto pull the chalkboard off of the wall with 100N of force, but fail. How mu ch work was done? Question 9 {1 point) You slide a puck down a frictionless surface at a constant velocity. How much work was done? Question 10 (1 point) Do you think the Skater will make it over the first hump? (No friction on the track) meters OYes, because all of his potential energy will be converted to kinetic energy O No, because he doesn't have enough potential energy Yes, because some of his energy will be potential and some kinetic O No, because his potential energy will be converted to thermal energyQuestion 11 (1 point) Do you think the Skater will make it over the first hump? (Lots of friction on the track) meters Yes, because some of his energy will be potential and some kinetic Yes, because all of his potential energy will be converted to kinetic energy No, because he doesn't have enough potential energyQuestion 12 {1 point] In the next moment, the KE piece of the pie gets larger, then O The Skater is going up hill [left] 0 The Skater is going down hill (right) 0 There is no wag,r to tell Question 13 (1 point) A 5000 kg coaster is released 20 meters above the ground on a frictionless track. What is the approximate speed at ground level? (point A) C Start B A O 10 m/s 7 m/s 14 m/s O 20 m/sQuestion 14 {1 point) Photosynthesis is a process that performs which energy transformation? 0 radiant energy a chemical energy + thermal energy O thermal energy a chemical energy O chemical energy a radiant energy + thermal energy O thermal energy a radiant energy
