B. In WW2 this is what they were known as....but this is physics.
Rake bc it does not use anything no lever or anything
Answer:
Moving them farther apart
Explanation:
The electric field between the two charges Q and q separated by a distance r is given by
It shows that the electric field is inversely proportional to the square of the distance between two charges.
So, as the distance between two charges increases, the electric filed between the two charges decreases.
Answer:
The maximum emf that can be generated around the perimeter of a cell in this field is
Explanation:
To solve this problem it is necessary to apply the concepts on maximum electromotive force.
For definition we know that
Where,
N= Number of turns of the coil
B = Magnetic field
Angular velocity
A = Cross-sectional Area
Angular velocity according kinematics equations is:
Replacing at the equation our values given we have that
Therefore the maximum emf that can be generated around the perimeter of a cell in this field is
Answer:
8 minutes and 20 seconds
Explanation:
5000/10 to get the number of seconds, which is 500, then you convert 500 seconds to minutes and you get 8 minutes and 20 seconds
