An ant sits on a cd at a distance of 17 cm from the centre. If it sits there for 42 seconds, it travels a total distance of 913 cm. a. What angle has the ant turned through? (in radians) b. What speed has the ant been traveling at? (in cm/sec) c. What angular velocity has the ant been spinning at? (in radians/sec) d. What rpm is the cd turning at?

4.at 0 ºc, some amount of energy is required to change 1 kg of water from a solid into a liquid. if you had a 2 kg piece of ice, what effect would this have on the amount of thermal energy required to change the water from a solid to a liquid? it would require more energy to change solid water into liquid water because there are more molecules in this larger piece of ice. it would still require the same amount of energy to change solid water into liquid water because the entire piece of ice would still gain the same amount of energy in each case. it would require energy to be removed from the 2 kg piece of ice. the larger piece of ice already has more total energy than the smaller piece of ice, so energy must be removed for the ice to become liquid. it would require less energy to change solid water into liquid water because the energy would spread through the ice more quickly and the ice already has a larger total amount of energy because it is larger than a 1 kg piece of ice.
