svetoff [14.1K]

Work done against gravity to climb upwards is always stored in the form of gravitational potential energy

so we can say

W = mgh

here h = vertical height raised

so here we know that

h = 14.1 sin7.3 km

here we have

h = 1.79 km

now from above equation

W = (83 kg)(9.81 m/s^2)(1.79 \times 10^3 m)

W = 1.46 \times 10^6 J

so work done will be given by above value

In the circuit seen here, the resistor has a resistance of 3 ohms. If no change in the battery size occurs, what will happen to
Bumek [7]
The current will decrease as the resistance has now increased, meaning less current will be 'let through' the resistor. (assuming it's in series, there's no image)
