because you gotta go fast jk if take mph miles per hour that's a distance and a time there for you would be able to calculate speed
Answer:
0.00299T
Explanation:
The magnetic field B = 0.00299T
Answer: If a force on an object is aimed in the direction of the object’s velocity, the force does positive work
(b).
Explanation:
Hi, the answer is oprion b. positive work.
If a force on an object is aimed in the direction of the object’s velocity, the force does positive work.
An object's kinetic energy will only change if the force acting on the object changes the object's speed. This will only happen if there is a component of the force in the direction that the object moves.
So, A force will do work only if the force has a component in the direction that the object moves.
