Explanation:
1st- states that when two bodies interact, they apply forces to one another that are equal in magnitude and opposite in direction.
2nd- states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it. (most important law)
3rd- states that when two bodies interact, they apply forces to one another that are equal in magnitude and opposite in direction. (law of action/reaction)
That depends on how soon you want it to reach 5 m/s/s. Without friction, ANY force will accelerate the car, like a mosquito pushing on it, but a Space Shuttle booster will accelerate it at a greater rate.
The answer to this question would be A. Interference. This is because when two sounds with slightly different frequencies creates a periodic variation in volume.
Answer:
Current in the wire is given as
Explanation:
magnetic field due to long current carrying wire is given as
so we have magnetic force on moving charge is given as
so we have
so we have
