Actually, when the refrigeration liquid is vaporized, the cooling effect is produced
The answer would be a speed
Yes it is, it was made in France as a gift to the U.S.A.
According to Newton's 2nd law of motion:
F = m * a where F is the force applied in Newtons, m is the mass of the object in kg, and a is the acceleration of the object in m/

.
Therefore the force applied in this situation is simply:
F = 6 kg * 2.3 m/

= 13.8 N
Hope this helps!
