Aperson holds a rifle horizontally and fires at a target. the bullet leaves the muzzle of the rifle with a velocity of 460 m/s. two seconds later the person hears the bullet strike the target.

if the speed of sound in air is 340 m/s, calculate the distance travelled from the bullet to the target.

During the refrigeration cycle, what does the refrigerant do? absorbs and releases thermal energy by first vaporizing then condensing. absorbs and releases thermal energy by first condensing then vaporizing. insulates the thermal energy away from the cooling area. transfers thermal energy to the cooling area by condensing.
