Assume that, as the battery wears out, the voltage decreases at 0.03 volts per second and, as the resistor heats up, the resistance is increasing at 0.02 ohms per second. When the resistance is 100 ohms and the current is 0.02 amperes, at what rate is the current changing

Explanation:

From the question we  are told that

Voltage decreases at  

Resistance increase at

Resistance at

Current at

Generally the equation for ohms law is mathematically represented as

Therefore

Generally making subject of the formula in the above equation mathematically gives

Therefore

Generally it is given that the change in current is

a sonic boom is a loud boom that breaks the sound barrier

explanation:

amplitude
