Q1. The diagram shows a helicopter being used to rescue a person from the sea.
(a)
(i)
The mass of the rescued person is 72 kg.
Use the equation in the box to calculate the weight of the rescued person.
gravitational field strength = 10 N/kg
Show clearly how you work out your answer.
Weight = N
An electric motor is used to lift the person up to the helicopter. The motor lifts the person at a constant speed.
State the size of the force, T, in the cable.
Force T = N

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.
