Answer:
Conduction
Conduction is the movement of heat through a substance by the collision of molecules. At the place where the two object touch, the faster-moving molecules of the warmer object collide with the slower moving molecules of the cooler object.
Answer:
here 20 lb object will hit the ground first
Explanation:
Acceleration of the object while it is dropped in air is given as



so acceleration of the object is independent of the mass of the object
now time to reach the ground is given as


for 20 pound object


for 50 pound object


Shampoo has a higher density
Answer:
Using the Newton equation
V²=U² +2as
Given; V=9.2m/s U = 0m/s( because it starts from rest)
S=26.2m.
9.2²=0²+2(26.2)a
a =9.2²/2(26.2)
a=84.6/52.4
a=1.60m/s²
