If a runner exerts 457 j of work to make 321 w of power then how long did it take the runner to do the work
1 answer:
The time taken by the runner to do the work is 1.42 seconds.
Given the data in the question;
- Work done;
- Power;
- Time elapsed;
Power can be simply referred to as the quantity of energy transferred per unit time.
It is expressed as;
Where W is work done and t is time elapsed.
To determine the time it took the runner to do the work, we substitute our given values into the expression above.
Therefore, the time taken by the runner to do the work is 1.42 seconds.

Answer: Option (b) is the correct answer.
Explanation:
According to ohm's law, the relationship between voltage, resistance, and current is that current passing through a conductor is directly proportional to the voltage over resistance.
Mathematically, I =
From this relationship we can see that when we decrease the voltage, and do not change the resistance, the current will also decrease. As current is directly proportional to voltage and inversely proportional to resistance.
