Final answer:
To do 104 joules of work in 8 seconds, it takes 13 watts of power.
Step-by-step explanation:
To calculate the power required to do a given amount of work over a specific period of time, we use the formula:
Power = Work / Time
Using the provided numbers:
Power = 104 J / 8 sec = 13 W
Thus, it takes 13 watts of power to do 104 joules of work in 8 seconds. Remember, 1 watt equals 1 joule per second, and this formula is derived from that relationship.
