"In the old West, a marshal riding on a train traveling 32.0 m/s sees a duel between two men standing on the Earth 70.0 m apart parallel to the train. The marshal's instruments indicate that in his reference frame the two men fired simultaneously."
(a) Which of the two men, the first one the train passes (A) or the second one (B) should be arrested for firing the first shot? That is, in the gunfighter's frame of reference, who fired first?
(b) How much earlier did he fire?
(c) Who was struck first?

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is

i don't understand. explain it clearly

pythagoras' theorem

square root (-5^2+9^2)

square root (25+81)

square root (106)

angle is tan^-1(9/5)

neg x, pos y

the correct answer is "inertia"
