Answer:
Explanation:
In our previous articles, we observed the theoretical formulas of Ohm’s law, its calculations in the lab report, and experiment. Today you’ll learn the verification of theory vs experimental results on a 1 kΩ resistor.
The theoretical results are obtained from the formula of Ohm’s law: V = IR. The experimental verification is provided for a metal film 1 kΩ (±0.05%). We have used a high-quality resistor with negligible tolerance value so as to reduce the tolerance error.
The little problem in our calculations arises due to improper handling of multimeter probes. You can learn the complete method to perform the Ohm’s experiment here and can calculate the current values by using the Ohm’s law calculator.

Answer:
a
Explanation:
When people jump from greater height, energy gets absorbed into the muscles as potential. And when the person flexes her legs on landing energy is trans formed not only into elastic energy in the bones, but also into elastic energy in other tissues and into thermal energy.
air resistance is very small hence, negligible. So, the statement a is correct and rest are wrong.
Answer:
an electric motor
Explanation:
electric motor contains an electromagnet that can rotate between poles of a magnet.
