The time period t of a simple pendulum is given by the relation
t=2pi sq rt l/g
, where l is the length of the pendulum and g is the gravitational field at the place. from the above relation, we can say that:

t ∝ g

t ∝ l

t2 ∝ g

t2 ∝ l

answer:   you might love summer weather, but you don’t want it to feel like the sun is inside your car. but a hot car that just won’t seem to cool down might be a bigger of a problem than you think. your car relies on being at the right temperature.
