Max: 152 million km
min 146 million km
I think that numbers one, three, and four are true
Answer:
1110 N
Explanation:
First, find the acceleration.
Given:
Δx = 300 m
v₀ = 85.5 km/h = 23.75 m/s
v = 0 m/s
Find: a
v² = v₀² + 2aΔx
(0 m/s)² = (23.75 m/s)² + 2a (300 m)
a = -0.94 m/s²
Find the force:
F = ma
F = (1180 kg) (-0.94 m/s²)
F = -1110 N
The magnitude of the force is 1110 N.

Explanation:
Electrical resistance can be defined as the opposition to the flow of current in an electric circuit or wire. The resistance converts electrical energy into thermal energy, this serves as friction in mechanical systems. And this electrical energy converted to thermal is dissipated.
By ohm's law we have
Resistance R = Voltage V/ Current I
