Answer:
The centripetal acceleration changed by a factor of 0.5
Explanation:
Given;
first radius of the horizontal circle, r₁ = 500 m
speed of the airplane, v = 150 m/s
second radius of the airplane, r₂ = 1000 m
Centripetal acceleration is given as;

At constant speed, we will have;

a₂ = 0.5a₁
Therefore, the centripetal acceleration changed by a factor of 0.5
It depends on the circuit. Sometimes it becomes a bit weaker, sometimes it stays the same.
1. Proton
2. negative ion
3. electric charge
4. electron
5. repel
6. attract
7. positive ion
I think it is D
Hope my answer help you?
The answer would be to research the need. This should have been done before the project began.
