Answer:
Explanation:
a) The magnitude of the net force on the student = 0 N since the student is standing still on level ground and upward reaction force = downward force.
b) the magnitude of the contact force on the student by the backpack = 80 N since the student was backing the backpack
c) the magnitude of the contact force o the student by the ground = 550 N + 80 N = 630 N reactional force on the student

<u>Answer:</u>
Specific Heat
<u>Explanation:</u>
Specific heat is the measurement which describes the amount of heat needed to raise the temperature of one gram of a material by one degree Celsius.
It is the amount of heat required per unit mass to raise the temperature by one degree Celsius. The relationship between heat and the temperature change is usually expressed as shown below:
Δ
where 
= heat added,
= specific heat,
=mass; and
Δ = change in temperature
