Answer:
It will take time=7.963 hours to completely discharge
Explanation:
The energy available in the battery is:
Energy stored=Power×Time
Energy stored=(ΔV)I×t
Energy stored=(12.0V×43.0A.h)
Energy stored=516 W.h
The two headlights together consume a total power of:
So the time required to completely discharge is:
It will take time=7.963 hours to completely discharge
Answer:
pretty sure its long term but im sorry if im wrong
Explanation:
Answer:
Distance is 800 m and Displacement is 0 m
Explanation:
Total Distance
= 400(2)
= <u>800</u><u> </u><u>m</u>
Total Displacement
= <u>0</u><u> </u><u>m</u> since she returns to the same spot
Answer:
The escape speed of the planet is 41.29 m/s.
Explanation:
Given that,
Speed = 52.9 m/s
Final speed = 32.3 m/s
We need to calculate the launched with excess kinetic energy
Using formula of kinetic energy
We need to calculate the escape speed of the planet
Using formula of kinetic energy
Hence, The escape speed of the planet is 41.29 m/s.
Answer:
According to Newton's first law of motion, an object maintains its state unless a force acts on it. Therefore, a moving car does not change its direction and keeps its speed unless a force acts on it.
