The headlights are shining on a truck travelling at 100 km/h. the speed of the light from the headlights relative to the road will be:

a) c

b) c + 100 km/h

c) c – 100 km/h

d) depends on the temperature, but faster than the speed if the truck was not moving.

e) faster than if the truck was not moving, but impossible to calculate with the given information

Acombination reaction is when two or more combine to form one product. a decomposition reaction is when a substance breaks down into two or more simpler substances in a chemical reaction.

Two kilograms of air within a piston–cylinder assembly executes a carnot power cycle with maximum and minimum temperatures of 800 k and 300 k, respectively. the heat transfer to the air during the isothermal expansion is 60 kj. at the end of the isothermal expansion the volume is 0.4 m3. assume the ideal gas model for the air. determine the thermal efficiency, the volume at the beginning of the isothermal expansion, in m3, and the work during the adiabatic expansion, in kj.
