Explanation:
(a) The period of a wave is the time required for one complete cycle. In this case, we have the time of five cycles. So:
(b) The frequency of a wave is inversely proportional to its period:
(c) The wavelength is the distance between two successive crests, so:
(d) The speed of a wave is defined as:
Answer: velocity
Explanation: Hope this helps :)
The capacitance is defined as the maximum charge stored in a capacitor, Q, divided by the voltage applied, V:
The capacitor is initially charged with the battery of 108 V, so the the initial charge on the capacitor can be found by re-arranging the previous formula:

Answer:
<h3>4905N</h3>
Explanation:
The force needed to keep the elephant from slowing down is expressed as shown according to Newtons second law of motion.
Force = mass * acceleration due to gravity
Given
Mass of elephant = 500kg
acceleration due to gravity = 9.81m/s²
Force = 500*9.81
Force = 4905N
<em>Hence the force needed to keep the elephant from slowing down is 4905N</em>
