Question

question 1 of 10
a computer monitor uses 200 w of power. how much energy does it use in
10 seconds?
a. 200 j
b. 20 j
c. 2000 j
d. 20,000 j

Explanation:

Step1: Recall the formula for energy

Energy \( E = P\times t\), where \( P\) is power and \( t\) is time.

Step2: Substitute the given values

Given \( P = 200\space W\) and \( t=10\space s\). Then \( E=200\times10\).

Answer:

C. \( 2000\space J\)
