a car is traveling at a velocity of 13.5 m/s north on a straight road. the mass of the car is 1,300 kg. a
motorcycle passes the car at a speed of 30 m/s. the motorcycle (with rider) has a mass of 350 kg
calculate and compare the momentum of the car and motorcycle. which has the greater momentum
and why?

Exothermic,  physical change after it is already baked

The answer is probably c. xylem

Ans. : frostbite is when exposure to cold temperatures causes freezing to the skin or other tissues. it most commonly affects the hands, feet, and face. the longer areas are exposed to cold, typically the worse the frostbite. the water temperature used for rewarming a frostbitten part should be : (102 -105) f degrees.
