Answer:
The electric field strength at the midpoint of the line joining the charges is zero (0)
Explanation:
Given that the two charges are both positive (same charge) and are equal in magnitude that is 6uC. The electric field strength at the midpoint of the line joining the two charges will be equal and opposite in magnitude, therefore they will cancel each other out and the electric field strength at this point will be equal to zero.
Answer:
B. Ultraviolet.
Explanation:
Io is the fourth smallest moon in the Galilean moons and it is the innermost moon out of the other three moon. It has the highest density as compare to the moon and it has lowest water at its surface.
While it is Jupiter moon it leaves a footprint of magnet over the Jupiter's upper atmosphere. The appearance of this moon look like as a spot of ultraviolet emission that remains fixed underneath Io as Jupiter rotates. So it reflects Ultraviolet radiations.
Answer:
Explanation:
Frequency is oscillations per second.
So we have to find the Number of seconds she paced.
2 minutes = 2 X 60
= 120 seconds
Therefore,
Her frequency = 10 / 120
= 1/12 Hertz
