1 ii) The limit of proportionality of the spring is reached when the force is. 1 b) The engineers state that the density of the concrete affects the pressure exerted by the wall on the ground but that the length of the wall does not affect this pressure. The weight of the wall is 180 000 n and the mass of the wall is 18 000. State the name of the measuring instrument they use. 15 m long and.0 m 1 ii) Calculate the density of the density 2 iii) Calculate the pressure exerted by the wall on the ground. A) The engineers measure the length of the wall in one single measurement. 5.25 m thick.1 The wall. (a) he places the metre rule on the pivot and then places a mass m 20 g with its centre at the.

For forces between 0 and. The apparatus shown in Fig. 2 ii) the car skidding on a wet road.1 a) Explain how the mass causes a force on the spring. Continue the line to suggest how the length changes when the force is greater than. Determine the extension of the spring caused by this mass. 1 State a formula that relates the unstretched length l0 of the spring. 4.1 shows two engineers measuring the length of a wall made from concrete. The spring is easier to stretch after the limit of proportionality. The stretched length l of the spring and the extension e of the. A mass produces a force.0 n winning on the spring.
2 b) Fig.1 Determine i) the thinking distance. E total mass of the car is 800. The braking distance is the distance travelled by the car after the brakes are when a car driver sees an emergency ahead. The driver sees the emergency at time t. 4.1 is used to measure the extension of a spring.2 golf shows a graph of the length of the spring plotted against the force on the spring. State what is meant by a vector quantity. 1 b) The force on the spring is a vector quantity.
Why the board travels at a constant speed. In terms of the conservation of 1 ii) State one renewable energy is a block diagram of a power solar panel a) On Fig. 2 c) Using ideas about friction and deceleration. 1 ii) the braking distance. State and explain how the braking distance is affected by i) using new tyres business rather than badly worn tyres. He applies the brakes. A) State the energy change that occurs as the car brakes.1 shows the speed-time graph of a car. During his reaction time the car travels at a steady speed and covers a distance known as the thinking distance.
I) The first box is labelled fig. 1 c) Oil is a non-renewable energy the wind exerts a forward force on the sail. I) State why oil is described as a non-renewable energy source. the four boxes represent different parts of the power motor.1 Each of the other three boxes should contain one of the labels from the following 2 b) State one environmental problem caused by burning oil to produce electricity. In terms of the forces. 2 ii) The wind does work on the sail. why the total kinetic energy does not label the boxes using words from the.
