Heating element
When all four heating elements are switched on at full power the hob draws a current of
26 A from the 230 V mains electricity supply.
(a)
Calculate the resistance of one heating element when the hob is switched on at full
power.
Give your answer to 2 significant figures.

Aballoon is rising vertically upwards at a velocity of 10m/s. when it is at a height of 45m from the ground, a parachute bails out from it. after 3s he opens his parachute and decelerates ata a constant rate 5m/s.when. (a) what was the height of the parachutist above the ground when he opened his parachute? (b)how far is the parachutist from the balloon at t=3s? (c)with what velocity does the parachutist hit the ground? (d)after how long does the parachutist hit the ground after his exist from the balloon?
