An engineering student claims that a refrigerator under development will absorb 1300 J of heat per cycle from its cabinet and
release 1200) of heat per cycle into the surroundings. Is it possible for this claim to be true?

A)Yes, if the motor for the refrigerator performed at least 100 ) of work per cycle.

B)No, because heat can never be transferred from a cold reservoir to a hot reservoir.

C)No, because this refrigerator would violate the first law of thermodynamics.

Acommon technique in analysis of scientific data is normalization. the purpose of normalizing data is to eliminate irrelevant constants that can obscure the salient features of the data. the goal of this experiment is to test the hypothesis that the flux of light decreases as the square of the distance from the source. in this case, the absolute value of the voltage measured by the photometer is irrelevant; only the relative value conveys useful information. suppose that in part 2.2.2 of the experiment, students obtain a signal value of 162 mv at a distance of 4 cm and a value of 86 mv at a distance of 5.7 cm. normalize the students' data to the value obtained at 4 cm. (divide the signal value by 162.) then calculate the theoretically expected (normalized) value at 5.7 cm.
