Answer:
Option D => it is moving from high potential to low potential and losing electric potential energy.
Explanation:
Consider a big circle, within the circle we have force, F. That force, F is known as the Electric Field and inside the region or field or space, charged particle or object will be able to exerts force on the other objects.
Electric Field can be represented mathematically by using the formula below; E = kQ/r^2.
So, let us answer the question with what we have considered above. It is worthy of note to know that electric Field moves from a region of higher potential to a region of lower potential. So, any option that says this is correct.
But, there is only one problem and that is the fact that the question asked us about the direction of the movement of proton. Since, proton is s a positive charge, it is going to lose electric potential energy. So, Option D is correct.
Answer:
73.152cm
Explanation:
We have been given:
0.8yards of rain
Problem, convert to cm = ?
Solution:
The problem deals with the conversion from one length dimension to another.
So:
1 yard = 91.44 cm
So 0.8 yards = 0.8 x 9.44 = 73.152cm
The solution to this problem is 73.152cm
B. Frequency divided by wavelength
