Final answer:
To calculate the energy used by the mobile phone charger, we need to use the formula: Energy (in Joules) = Power (in Watts) × Time (in seconds. The mobile phone charger uses 1,555,200 Joules of energy when plugged in for 36 hours.
Step-by-step explanation:
To calculate the energy used by the mobile phone charger, we need to use the formula: Energy (in Joules) = Power (in Watts) × Time (in seconds). First, convert the current from Amperes to Watts by multiplying it with the voltage. So, the power used by the charger is 0.10 A × 120 V = 12 Watts.
Now, we can calculate the total energy used by the charger by multiplying the power with the time: Energy = 12 W × 36 hours × 3600 seconds/hour = 1555200 Joules.
Therefore, the charger uses 1,555,200 Joules of energy when plugged in for 36 continuous hours.
