Answer 1

Answer:

$the \: answer \: for \: this \: question \: is \: d.40w$

Explanation:

Greetings !

Given values

• Work(W)= 800J
• time(t) = 20 second
• Weight = 500N

required value

• power(P) = ?

Solution:

Firstly, recall the work-power equation

• work=power*time
• w=p*t

substitute known values to the equation

• (800)=P*(20)

Solve, for P (power)

• P=40.0w
