Answer: a centripetal force is toward the center of curvature, the same as the direction of centripetal acceleration. According to Newton's second law of motion, net force is mass times acceleration: net . For uniform circular motion, the acceleration is the centripetal acceleration
Explanation:
The principal reason voltage is
induced in the loops of a generator coil is that the loops are rotating,
changing the amount of magnetic field within the loops. The answer is letter A.
For example, in a circuit, the electrons in
the bulb will not move without the potential difference or voltage. When there
is voltage, electric current occurs because there is a driving force for the
electrons in the wire to move.
Answer:
1430 m/s
Explanation:
In this problem, the speed of sound in water is given by:
where
d is the distance travelled by the sound in water
t is the time taken
In this problem, we have:
d = 6,006 m
t = 4.2 s
So, the speed of sound in water is
