The kinetic energy of a moving car is less than the amount of chemical potential energy that is released when fuel is burned in the engine. Which
statement best explains why this is so?
A. More of the car's energy is transformed into potential energy the
faster it goes.
B. Friction causes some of the energy released by the fuel to be
transformed into thermal energy,
C. Some chemical energy is transformed into potential energy as the
particles in the fuel are rearranged.
D. The force of gravity transforms some kinetic energy into
gravitational potential energy.

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.
