|
|
|
The force like quantity in the equation for electrical work is:
|
Charge; if it has charge in or delta it's the force like quantity
|
|
|
One ampere equals:

one coulomb per second
|
|
|
When a substance (such as water) goes from a solid to a liquid state without a change in temperature, the heat added during the transformation is called:
|
Latent Heat
|
|
|
Rearrange the formula, Rt=L/kA, to solve for L
|
L=Rt(kA)
|
|
|
What is Sensible heat?
|
when heat is added to a substance and the temperature of the substance increases the heat is called this.
|
|
|
What is Latent heat?
|
When heat is added to a substance and the temperature DOES NOT change but the substance changes STATE, the heat thats added is called this.
|
|
|
Tension, compression, bending, and twisting are kinds of mechanical:
|
Stress
|
|
|
A resultant force has both magnitude and:
|
Direction
|
|
|
The measure of gravitational pull is:
|
Weight
|
|
|
The SI units of mechanical force are:
|
Newtons or kilogram weight
|
|
|
Torque is a measure of what kind of force?
|
Rotational
|
|
|
Total pressure above zero pressure is:
|
Absolute pressure
|
|
|
In fluid systems, the quantity that has no units is:
|
Specific Heat
|
|
|
Sea level air pressure is:
|
14.7 lb/inches squared
|
|
|
Voltage difference is measured with a/am:
|
VOM
|
|
|
A term that pertains to DC voltage is:
|
Anode
|
|
|
Heat energy moves from:
|
Warmer regions to cooler regions
|
|
|
Fluid-flow rate units such as "kg per min" or "gm per sec" are units of:
|
Mass-Flow rate
|
|
|
what is net force?
|
determines which way it will move
|
|
|
what is Equilibrium?
|
if the system is at rest when the force are applied, it remains at rest.
|
|
|
what is scalar value?
|
gives only magnitude (how much)
|
|
|
what is vector?
|
gives both magnitude and direction
|
|
|
what is absolute pressure?
|
is the total pressure measured above a reference of zero pressure- a perfect vacuum
|
|
|
Think of temperture difference as what?
|
as Force
|
|
|
what is heat energy?
|
thermal systems are designed to move heat energy from warmer regions to cooler regions-usually to remove excessive heat
|
|
|
what is force?
|
push or pull
|
|
|
what is an Electron?
|
electrons are in a charge
|
|
|
what is charge?
|
needed for electrical systems to do work moves electricity
