Answer:
True
Explanation:
Whenever electrons are transferred between objects, neutral matter becomes charged. For example, when atoms lose or gain electrons they become charged particles called ions. Three ways electrons can be transferred are conduction, friction, and polarization. In each case, the total charge remains the same.
I tried, hope this helps :)
* I might be wrong though
If the car is going at constant speed than the velocity isnt changing, only the direction of velocity.
Answer:
The strength of magnetic field is T
Explanation:
Given:
Length of rod m
Velocity
Induced emf V
According to the faraday's law
Induced emf =
We have to find strength of the magnetic field,
T
Therefore, the strength of magnetic field is T
Answer:
When the speed is changing is the correct answer
Explanation:
Because acceleration is rate of change of velocity
PLEASE MARK ME BRAINLIEST IF MY ANSWER IS CORRECT PLEASE
I beleve it is 15 if not sorry
