Answer :
The ice cube takes around 5.11 minutes to melt.
To find out how long it takes for the ice cube to melt in the microwave oven, you can use the formula:
Time (s) = Energy (J) / Power (W)
It is given that the microwave delivers 105 W of power and it takes 32,200 J to melt the ice cube.
Plugging in the values to the above formula, we get:
Time (s) = 32,200 J / 105 W
Time (s) ≈ 306.67 seconds
Converting this time in minutes we get:
Time (s) ≈ (306.67/60) minutes
Time (s) ≈ 5.11 minutes
So, it takes approximately 5.11 minutes for the ice cube to melt in the microwave oven.
