&lt;br /&gt;
state teh effect if any on the period of the pendulum when&lt;br /&gt;
&lt;br /&gt;
a)a heavier pendulum bob of the same size is used&lt;br /&gt;
&lt;br /&gt;
b)there are a larger number of oscillations&lt;br /&gt;
&lt;br /&gt;
c) there is a smaller angle of swing&lt;br /&gt;
&lt;br /&gt;
d)a longer pendulum is used&lt;br /&gt;
&lt;br /&gt;
assuming all otehr factors are constant&lt;br /&gt;
&lt;br /&gt;
TIA&lt;/div&gt;
&lt;/blockquote&gt;
&lt;p&gt;For question c, angle displacement actually does affect the
period of pendulum swing. It's due to some air resistance blah. But
in theory, you gotta stick to conventions, and that's the period
remains the same.&lt;/p&gt;</description>

TIA&lt;/div&gt;
&lt;/blockquote&gt;
&lt;p&gt;a) no change in period&lt;br /&gt;
b) assuming there is no air resistance, the period will be the
same&lt;br /&gt;
c) no change in period&lt;br /&gt;
d) period will increase&lt;/p&gt;</description>
