Question 10

A deep space probe is exploring the outer solar system. It is powered by solar cells and propelled by an ion thruster.

a.

The total area of the probe's solar cells is 42.5 m2. At its current distance from the Sun, each 1.0 m2 of solar cell generates 0.180 kW of electrical power. Calculate the total electrical power generated by these solar cells.

[2]
b.

The probe's ion thruster produces a constant thrust force of 84 mN. Calculate the change in momentum of the probe when the thruster runs continuously for 35 minutes35\text{ minutes}35 minutes.
