If an object takes 60 seconds to heat up in a microwave and I need to cook two of them, do I put the microwave on for 60 seconds or 120 seconds?

In reality, you need to put the microwave on for some time between 60 seconds and 120 seconds depending on a number of factors. In the case that the object absorbs all the microwave energy then you would need 120 seconds because you need double the amount of energy to heat the two objects. In the case of an object which absorbs almost none of the microwave energy, you would only need the same amount of time for two objects.

It is difficult to give a good theoretical answer to this question because the situation is so complex. The microwaves are reflected and absorbed by a number of different surfaces inside the microwave including the object being microwaved, the turntable and the walls of the device. The placement of the objects in the microwave will affect how they interact with the microwaves too.

This is a question where experimentation will give you the best idea.
