Answer:
52 minutes
Explanation:
Given the following data;
Voltage = 1.5 V
Current = 2 Amperes
Energy = 9360 J
To find how many minutes will the battery last before it runs out of energy;
First of all, we would determine the power rating of the toy
Power = current * time
Power = 2 * 1.5
Power = 3 Watts
Next, we find the time;
Energy = power * time
9360 = 3 * time
Time = 9360/3
Time = 3120 seconds
To convert to minutes;
60 seconds = 1 minute
3120 seconds = 3120/60 = 52 minutes
