Question 1
This question is in two parts. Part 1 is about solar radiation and the greenhouse effect. Part 2 is about a mass on a spring.
Part 1 Solar radiation and the greenhouse effect
The following data are available.
Question (a)
Outline the conditions necessary for the object to execute simple harmonic motion.
Question (i)
Sketch on the same axes a graph of how the displacement varies with time if a small frictional force acts on the object.
Question (b)
Point P now begins to move from side to side with a small amplitude and at a variable driving frequency f. The frictional force is still small.
At each value of f, the object eventually reaches a constant amplitude A.
The graph shows the variation with f of A.
Question (i)
On the same axes, draw a graph to show the variation with f of A when the frictional force acting on the object is increased.
