If you must evacuate PACE Studio 1 (Ground Floor of 10 College Walk) in an emergency, the evacuation area to which you must go is:

Before using any mains electrical equipment you must:

First year physics and astronomy classes are held in PACE (the ground floor of 10 College Walk). Select the Building Warden of this building.

If you wish to drink during a class you should:

It is important that you wear appropriate footwear in the ground floor Studios. You will not be allowed to attend a class if you are wearing:

You must wear a lab coat to all physics and astronomy practical classes.

You had a wild night at a party the night before your class, and at the start of your class you are still feeling the effects of the alcohol or drugs you consumed. What should you do?

If a person requires CPR and you are asked to go get a defibrillator, you should:

Suppose now you don't release the ball from rest, but instead give it some initial velocity in the direction perpendicular to the center of the spherical cap.  Do you expect the period of radial oscillation to be longer, shorter or the same?

In this experiment, you will be using a ball rolling in a spherical cap. Consider a ball of radius r_b, in a spherical cap of radius r_s.  Imagine that you place the ball inside the spherical cap at some small distance from the center of the cap, and let go.  Draw a clearly labelled diagram of this situation to familiarise yourself with the forces.

We will model this experimental setup as a pendulum; ignoring friction. Which of the following then (for the situation described previously) is the appropriate equation for the period of oscillation of the ball?
