To measure gravitational mass one of the methods includes using a spring balance. a balance is a type of scale that is different because it uses known mass to measure the unknown mass. so technically the method measures the weight.
also if you just want to know normal mass then just weigh the object on the scales because technically speaking when you want to see your weight you are actually seeing your mass. because mass never changes whilst weight is from the result of gravity and always changes, so yeah. I hope thos actually makes some sort of sense
The heat required to raise the temperature to a specific temperature change of a sample is related to the specific heat capacity of the substance. In this case, the heat can be calculated through mCpΔT = 350 g * 0.39 J/g C *25 C. This is equal to 3412. 5 Joules. Closest answer is C.
