Tectonic plates are large segments of the Earth's crust that move slowly. Suppose that one such plate has an average speed of 5.5 cm/year. Find the following: Q4). a). What distance does it move in 2 s at this speed? b). What is its speed in kilometres per million years? Measurement and Mensuration (show all working) Q5). The sides of a small solid rectangular prism are measured to be 2.45 0.01 cm high, 4.35 0.02 cm wide, and 6.4 0.1 cm long. Find its surface area and uncertainty in square centimetres using maximum and minimum values. Check your answer using percentage uncertainties. ). b). Find its volume and uncertainty in cubic centimetres using maximum and minimum values. Check your answer using partial differentiation.
