19) C because the object is stationary, the forces are balanced in all directions so no work is being done and therefore no energy is being transferred

20) B because heating it transfers thermal energy and passing a current transfers electrical energy. I think that shining a light for long enough may heat the block up so it could be D but I’m not sure if that’s what it’s asking

D. 40 W

Answers

Answer:

[tex]the \: answer \: for \: this \: question \: is \: d.40w[/tex]

Explanation:

Greetings !

Given values Work(W)= 800Jtime(t) = 20 secondWeight = 500N

required value power(P) = ?

Solution:

Firstly, recall the work-power equation

work=power*timew=p*t

substitute known values to the equation

(800)=P*(20)

Solve, for P (power)

P=40.0w

Hunter had a power of 40 W while pushing the couch across the room. The correct answer is D. The correct answer is 40W.

Given:

Work (W) = 800 J

Time (t) = 20 seconds

Power is the rate at which work is done or the rate at which energy is transferred. It is calculated using the formula:

Power (P) = Work (W) ÷ Time (t)

Let's calculate the power:

Power (P) = 800 ÷ 20

Power (P) = 40 W

Therefore, Hunter had a power of 40 W while pushing the couch across the room. The correct answer is D.
