Assume that there is no slipping between the cable. Which of the following sources of error would lead to an experimental result smaller than the standard value. Steam condenses on the cooler part of the heater. The equipment may be fixed or movable and they abandoned villages in the mountains www.

Comment on this claim. An electron moving with speed 1. Neglect the effects of gravity. Figure 5. You are given a toy skier, a metre rule and a long rough paper strip with adhesive tape on the bottom surface.

Your description should include the physical quantities to be measured and the result expected. Answers written Answers written in the margins will not be marked. Bungee jumping is an activity that involves jumping from a tall structure while the person is connected to it via a thick elastic cord.

When the bungee jumper jumps, the cord stretches after falling a certain distance. The bungee jumper is momentariiy at rest at the lowest point but then bounces back up into the air. The bungee jumper continues to oscillate up and down a few times before he comes to a complete stop. When answering the following questions, neglect the effects of air resistance.

In terms of the net force acting on the bungeejumper, explain why the cord has to be elastic. Microwaves of wavelength 2 cm emitted from a transmitter T pass through two slits A and B formed by metal plates.

The slits are separated by 6 cm as shown. A probe R connecting to a meter is moved from X to Y to detect the intensity of microwaves received. Transmitter T and point X are equidistant from A and B. In Figure 8. The horizontal scale is 1 cm to 5 cm. Carbon dating can be used to identify the age of some objects which have the MC isotope, as it is radioactive and decays by emitting a [Ii-particle.
