Answer:
the answer should be a constant
hope this helps!!
Answer:
1. a. increase
2. Because the electron has a negative charge its electric potential energy does not decrease as one might expect, but increases instead.
Explanation:
Lets first consider the relation between the electric field and electric potential.
E = -ΔV/Δs
As this equation indicates that the electric field is due to the change in potential and change in the the position of charge. Electric field is directed towards the decreasing potential and the electron moves in the opposite direction of the electric field where potential increases. Thats why the best explanation is that the electron has a negative charge it moves towards the positive region where the electric potential energy increases.
Answer:
The strength of the electric field is 
.
Explanation:
Given that,
Speed 
Time 
Angle = 45°
We need to calculate the acceleration
Using equation of motion
We need to calculate the strength of the electric field
Using relation of newton's second law and electric force
Put the value into the formula
Hence, The strength of the electric field is .
Answer:
μ =tanθ
Explanation:=
The ratio of the force of static friction and the normal reaction is equal to tanθ. F=mgsinθ. R = mgcosθ.
μ=tanθ
