That's the numerical answer that I got (don't forget to include your units in the future), with the possible exception of a negative sign.lonelypancreas said:

Hmm. The given answer choices differ from our answer by a factor of around √2, for what that's worth.lonelypancreas said:
Net heat flow is the transfer of thermal energy from one object to another due to a difference in temperature. It is also known as heat transfer or heat exchange.
Radiation is one of the three main mechanisms of heat transfer, along with conduction and convection. It involves the transfer of thermal energy through electromagnetic waves, such as infrared radiation.
The amount of net heat flow through radiation depends on several factors, including the temperature difference between the objects, the surface area of the objects, and the type of material the objects are made of.
No, radiation can also result in heat gain. For example, the sun's rays contain radiation that can be absorbed by objects, increasing their temperature and resulting in heat gain.
The net heat flow through radiation is typically measured in watts (W) or calories per second (cal/s). It can also be measured in joules (J) or British thermal units (BTU) depending on the unit system used.
