A cement factory takes in 300 tonnes of raw materials each day. The cement is produced in 25 kg sacks. 1 tonne = 1000 kg. Calculate how many sacks the factory could produce each day. ………………………………………………………………………………………………………. ………………………………………………………………………………………………………. Number of sacks = …………………….. 8. An ice cube floats in water, because it is less dense than the water. The total volume of the ice cube is 15 cm3. Only 1.5 cm3 of the volume of the ice is above the level of the water. Calculate the percentage of the total volume of the ice that is below the water level. ………………………………………………………………………………………………………. ………………………………………………………………………………………………………. ………………………………………………………………………………………………………. Percentage volume = …………………….. % 9. A student was using a stopwatch to measure the time taken for a toy car to travel down a ramp. The following times were recorded for her five repeat measurements: 1.56 s, 1.75 s, 1.58 s, 1.65 s, 1.71 s. (a) Calculate the mean of the five time measurements. ………………………………………………………………………………………………………. ………………………………………………………………………………………………………. mean = …………………….. S. (b) Calculate the range of the five time measurements ………………………………………………………………………………………………………. ………………………………………………………………………………………………………. range = ………………………… s (c) Calculate the uncertainty in time measurements ………………………………………………………………………………………………………. ………………………………………………………………………………………………………. uncertainty = ……………………………….. s4 Homework 1: Energy 1. A blender transfers energy usefully into which energy store? The kinetic energy store of the blades. The elastic potential energy store of the blades. The magnetic energy store of the blades. 2. The amount of energy transferred by an appliance depends on… … its power and size. … its power and mass. … its power and the time it is on. 3. What happens to the amount of energy in a car’s kinetic energy store when the car slows down? It remains the same. It decreases as some energy is destroyed. It decreases because some energy is transferred into other energy stores. 4. Which of these is a disadvantage of using solar cells to generate electricity? They are unreliable, because of the weather. The produce CO2 when running. They destroy wildlife habitats. 5. When an object falls from a height, the maximum energy transferred to its kinetic energy store is equal to… … the energy transferred to its gravitational potential energy store. … the energy transferred away from its gravitational potential energy store. … the energy transferred away from its thermal energy store. 6. Energy is conserved, this means it can be transferred usefully, stored or dissipated. What does dissipated mean? ……………………………………………………………………………………………………..5 Kinetic energy = 1/2 x mass x speed2 7. A go-kart travels on a straight track at 8.5 m/s. The combined mass of the driver and gokart is 160 kg. Calculate the total kinetic energy of the driver and go-kart. ………………………………………………………………………………………………………. ………………………………………………………………………………………………………. Kinetic energy = …………………….. J 8. A different go-kart travels on the straight track at 10.0 m/s. The total kinetic energy of this go-kart and its driver is 6,500 J. Calculate the total mass of go-kart and driver. ………………………………………………………………………………………………………. ………………………………………………………………………………………………………. Total mass = …………………….. kg 9. A third go-kart and driver have a total kinetic energy of 4.8 kJ and a combined mass of 150 kg. Calculate the speed of the third go-kart. ………………………………………………………………………………………………………. ………………………………………………………………………………………………………. ………………………………………………………………………………………………………. Speed = …………………….. m/s 10. A tennis ball has a mass of 60 g, and is served with a speed of 65 m/s. A cricket ball has a mass of 150 g and is delivered with a speed of 34 m/s. Using calculations, show which ball has the greater amount of kinetic energy [Show More]
