Answer:
The time required by the Athlete to work off 1.00 lb of body fat = 0.296 minute
Explanation:
1 lb of body fat = 4.1 k cal
1 k cal = 4.184 Kilo joule
1 lb of body fat = 4.1 × 4.184 = 17.1544 Kilo joule
Athlete expends 3480 Kilo joule in one hour
⇒ Time required to expand 3480 Kilo joule = 60 minute
⇒ Time required to expand 1 Kilo joule =
⇒ Time required to expand 17.1544 Kilo joule = × 17.1544 = 0.296 min
Therefore the time required by the Athlete to work off 1.00 lb of body fat = 0.296 minute

The planet that is considered or classified as a dwarf planet include the following: A. Hydra.
What is a planet?
A planet is a terminology which is used to describe a large astronomical (celestial) body that has sufficient mass to allow for self-gravity and make it assume a nearly circular shape or spherical shape.
Based on astronomical records, there are nine (9) planets in the solar system and these include the following;
- Mercury
- Venus
- Earth
- Mars
- Jupiter
- Saturn
- Uranus
- Neptune
- Pluto
In conclusion, we can reasonably infer and logically deduce that Hydra cannot be considered or classified as a dwarf planet because it is typically the moon of the dwarf planet, referred to as Pluto.

Final answer:
Both students do the same amount of work, but Ben delivers more power due to completing the work in a shorter time.
Explanation:
In this case, both Ben and Bonnie are lifting the same 50 kg barbell over their heads, but they are doing it at different rates. Bonnie lifts the barbell 10 times in one minute, which means she is doing the work over a longer period of time. Ben, on the other hand, lifts the barbell 10 times in 10 seconds, doing the work in a shorter amount of time.
The amount of work done is equal to the force exerted multiplied by the distance moved. Since the mass and distance are the same for both students, the work done is equal. However, power is defined as the rate at which work is done, which is calculated by dividing the work done by the time taken to do it. Since Ben completes the work in a shorter period of time, he delivers more power than Bonnie.
Therefore, Ben does the most work and delivers the most power.
