To warn the people that are going to be affected by it, for evacuations and such
Answer:
0.5A
Explanation:
V=IR where V is 1.5V, R is 3 ohms
Hence 1. 5= I x 3
1.5/3 =I
I =0.5 A
Current is 0. 5 amperes
Answer:
Mechanical energy is the sum of kinetic and potential energy of a system
Express the distance in meters:
d= 2 cm =0.02 m
V = Ed = 50 N/C * 0.02 m = 1 N/C m = 1 V = +1.0 V
As a result, although the Moon is moving to the east relative to the stars, the much faster westward motion of the sky is carrying it to the west, so despite its eastward motion relative to the center of the Earth, it rises in the east and sets in the west, just like any other celestial body.
