The height (h) of the water in metres at a certain point at the wave pool over a period of seconds is modelled by the equation h(s) = sin^2s + 1/2 sin s + 3/2.
a) How high is the water after 2 seconds?
b) During the first 10 seconds, how many times does the wave height reach 3 metres?
c) During the first 5 seconds, at what 3 points is the water level at 2 metres?

(a) If in a population, the shortest person is 1.5 metres tall and the tallest person is 2 metres tall, then the average height is always closer to 1.75 metres than to 2 metres.

Decide whether each of the following statements is either true or false. You MUST explain your reasoning. (a) If in a population, the shortest person is 1.5 metres tall and the tallest person is 2 metres tall, then the average height is always closer to 1.75 metres than to 2 metres. (b) If the correlation between two variables X and Y is positive, then Y is small (below the average Y value) whenever X is small (below the average X...

A lamp is installed at the bottom of a pool filled with water. The pool has depth d. The lamp produces light rays in all directions, but light only escapes from the top surface of the water within a circular region which has diameter D. (a) Explain why this effect occurs? (b) If the depth of the pool is 50 cm. Find the diameter D.

Under certain water conditions, the free chlorine (hypochlorous acid, HOCl) in a swimming pool decomposes according to the law of uninhibited decay. After shocking a pool, the pool boy, Geoff, tested the water and found the amount of free chlorine to be 2.4 parts per million (ppm). Twenty-four hours later, Geoff tested the water again and found the amount of free chlorine to be 2.1 ppm. What will be the reading after 2 days (that is, 48 hours)? When...

A certain spring is compressed 0.2 metres from its natural length by a force of 0.02 newtons. A 0.1 kilogram mass is attached to this spring. There is no damping, and the mass is acted on by an external force of 0.05 cos(0.8 t) newtons, where t is measured in seconds. At t = 0, the mass is released, at rest, from its rest (equilibrium) position. (a) Set up and solve the initial value problem for the displacement x(t) of...

A wave of water behaves like a plane wave with a frequency of 12 Hz breaks as it passes a sharp barrier between deep and shallow water. The velocity of the wave's propagation in the deep water is 24 cm/s, the angle of the wave reaching the barrier is 60o and the breaking wave angle at the barrier is 40o. a. What is the velocity of propagation of the wave in shallow water? b. What is the wavelength in the...

A rock is thrown at a window that is located at a height h = 36.33 m above the ground. The rock is thrown at an angle of θ above horizontal. The rock is thrown at time 0 seconds from a height of hi = 2.00 m above the ground with an initial speed of v0 and experiences no appreciable air resistance. After t = 2.0 seconds, let the velocity of the rock be v =(15.00 i + 6.38 j...
