Final answer:
Without the specific energy usage of the refrigerator, we cannot determine the exact time the 3.03 kW space heater would need to run to match the refrigerator's heat output. Typically, one would divide the total energy used by the refrigerator by the power rating of the heater to find the required time.
Step-by-step explanation:
The question is concerned with energy consumption and equivalences, specifically comparing the amount of heat energy output by a space heater and a refrigerator over a period. To address this question, one would need to know the amount of energy the refrigerator uses and then calculate how long the 3.03 kW space heater would need to run to produce an equivalent amount of heat energy.
Since the energy usage data for the refrigerator is not provided in the question, it is not possible to give a definitive answer. However, for illustrative purposes, if we know that a refrigerator uses X kilowatt-hours (kWh) of energy, we could find out how long it would take for a 3.03 kW heater to match that energy usage by dividing the total energy of the refrigerator by the power rating of the heater. This would yield the number of hours the heater needs to operate.
If the refrigerator used say, 6 kWh of energy, the calculation would be as follows: Time (hours) = Energy (kWh) / Power (kW) = 6 kWh / 3.03 kW, which would give us the time in hours.
