9 A particular experiment requires a very large current to be provided for a short time. (a) An average current of 200 A is to be supplied to a coil of wire for a time of
1.4 x 10 s. The resistance of the coil is 0.50.12.
Show that the charge that flows through the coil during this time is about 3 C.
Q=
fil) The circuit shows how a capacitor could be charged and then discharged through
the coil to provide the current.

The circuit contains a capacitor of capacitance 600 JF. This capacitor is suitable
to provide the current for 1.4 x 10's.
Explain why the capacitor is suitable.

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
