Answer:
Explanation:
Since this is an RC circuit, an RC circuit can be used to provide various time delays. The capacitor is connected in parallel across the lightbulb. WITH the battery connected , when the switch is closed , the capacitor voltage increases towards the battery voltage at a rate determined by the lightbulb resistance and the capacitance of the capacitor (called the time constant (τ)). The bulb will not emit any light and will act like an open circuit until the voltage across the capacitor reaches a certain level that can bright the bulb, when this voltage is reached the lightbulb brights gradually and the capacitor discharges through it, the lightbulb turns off again because the capacitor voltage drops fast and the capacitor recharges again and the lightbulb brights again

Answer:
Time = 40 s
It will take the spaceship 40s to coast that distance.
Explanation:
Using the impulse momentum equation;
Impulse = change in momentum
Ft = m(∆v) ........1
Given;
Force F = 1200kN
time of action t = 20s
Mass of spaceship m = 8.0×10^4 kg
∆v = change in velocity
Substituting the values into equation 1;
1200kN × 20s =8.0×10^4 kg × ∆v
∆v = 1200000×20/80000
∆v = 300 m/s
Since it was initially at rest, V0 = 0
Final velocity V2 = 300 + 0
V2 = 300m/s
Time To travel 12 km,
Time = distance/speed
Distance = 12 km = 12000m
Speed = 300m/s
Time = 12000/300
Time = 40 s
It will take the spaceship 40s to coast that distance.
