Question 1

[Maximum number: 4]

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.

Table for Question 1 — IB Physics SL

Question (a)

(a)

The sketch graph below shows how the displacement of the object from point O varies with time over three time periods.

Question (i)

(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)

(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)

(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.
