<span>Since a watermill is powered by a water wheel the strength of the current and volume of the water passing the mill may alter the amount of power provided. Seasonal and climatic changes could contribute to changes in the current.</span>
The statement about the battery which is correct is; a new substance is formed as the battery is used.
Lithium ion batteries have become part of most modern devices such as cell phone, laptop computers and other digital devices.
It shorter time of recharge and good battery life has continued to make it a top choice in the electronics industry.
The equation that describes the chemistry of lithium ion battery is;
LiC6 + CoO2 ⇄ C6 + LiCoO2
The reaction goes towards right hand side when the battery is in use and towards the left hand side when that battery is recharging.
Hence, from the equation, we can see that a new substance, LiCoO2 is formed when the battery is in use.

The wave characteristic that is the same for both waves is wavelength.
- Two waves with the same frequency will also have the same wavelength, amplitude, speed, and period. When two waves are travelling at the same frequency, it denotes that their duration and amplitude are also the same.
- When two waves of the same frequency and amplitude interfere constructively, their peaks and troughs align as shown in diagram A above. As a result, the original waves' amplitude is doubled, resulting in a sound wave that is twice as loud.
Thus, Equal frequencies are shared by two waves moving through the same region in the same direction.

The resistance needed to be added is R
The Current is 2 ma
The voltage reading is a maximum of 50 volts.
The ma meter has an internal resistance of 40 ohms.
Formula
E = I * R
Givens
E = 50
I = 2 ms
R = R + 40
Solution
E = I * R
I = 2 ma [ 1 amp / 1000 ma] = 0.002 amp
50 = 0.002 * (R + 40) Divide by 0.002
50/0.002 = R + 40
25000 = R + 40 Subtract 40 from both sides.
R = 25000 - 40
R = 24960 Answer
