Free_Kalibri [48]2 years ago
3 0

"watt" means "Joule of energy per second"

"60 watts" means "60 Joules per second"

(60 joules per second) x (5 seconds) = <em>300 Joules of energy</em>

4. How much work is done when you lift a 25 N box up to a 2 m shelf?
Semmy [17]

Answer:

<h2>50 J</h2>

Explanation:

The work done by an object can be found by using the formula

workdone = force × distance

From the question

force = 25 N

distance = 2 m

We have

workdone = 25 × 2 = 50

We have the final answer as

<h3>50 J</h3>

Hope this helps you

Which vehicle has the LEAST kinetic energy? 18-wheeler, minivan, car, or bike?
Whitepunk [10]

We can make pretty good guesses for their masses, but kinetic energy also depends on their speeds, which we don't know, and may change.

As an example ... If the truck, the van, the car, and the bike are all parked at the mall, then a scampering mouse has more kinetic energy than all of them combined.

As the question stands, no answer is possible.
