Answer:
Part A:
Part B:
Explanation:
<u> Part A:</u>
- Potential energy of charge at the given point,
- Charge,
The potential energy at a point due to a charge is defined as
.
<em>where</em>,
V = electric potential at that point.
Therefore,
<u>Part B:</u>
Now, if the charge at that point is replaced with 
, then the electric potential energy at that point is given by
Distance / speed. So, 63/35. Answes is 1.8
Answer:
Velocity of throwing = 34.335 m/s
Explanation:
Time taken by the tennis ball to reach maximum height, t = 0.5 x 7 = 3.5 seconds.
Let the initial velocity be u, we have acceleration due to gravity, a = -9.81 m/s² and final velocity = 0 m/s
Equation of motion result we have v = u + at
Substituting
0 = u - 9.81 x 3.5
u = 34.335 m/s
Velocity of throwing = 34.335 m/s
Chlorine needs to gain one electron and sodium needs to lose one electron
