Q:

Q = mcdT refers to

A) Enthalpy formula B) Heat Transfer formula
C) Specific Heat formula D) Heat of Vaporization
 
Answer & Explanation Answer: C) Specific Heat formula

Explanation:

Q = mc∆T refers to Specific Heat formula.

 

When heat energy is added to a substance, the temperature will change by a certain amount.

The relationship between heat energy and temperature is different for every material, and the specific heat is a value that describes how they relate.

 

Q = mc∆T

 

Q = heat energy (Joules, J)

m = mass of a substance (kg)

c = specific heat (units J/kg∙K)

∆T = change in temperature (Kelvins, K)

Q:

Rolling friction is caused by ____ from the following?

A) Non-elastic effects B) Gravity
C) Power dissipation D) Buoyancy
 
Answer & Explanation Answer: A) Non-elastic effects

Explanation:

Rolling friction or rolling drag is the force resisting the motion when a body rolls on a surface. It is mainly caused by non-elastic effects, that is, not all the energy needed for deformation of the wheel, roadbed, etc... is recovered when the pressure is removed.

Another cause of rolling resistance lies in the slippage between the wheel and the surface, which dissipates energy.
