Term
Matrix C is the product of the matrix multiplication AB. What is the
size of matrix B?
A=[4 2 3 1, 7 0 1 1, 0 2 3 1] C=[1 2 3 5, 2 1 2 5, 0 0 1 4, 4 7 6 2]
A) 3 X 3
B) 3 X 4
C) 4 X 3
D) 4 X 4
Give this one a try later!
For the matrix AB to be possible, matrix A must have the same number of
columns as matrix B has rows. The answer is B.
The equation for power is
P= ½VmaxImaxcos(theta)=VrmsIrms*cos(theta)
Therefore, to find the phase angle, theta, the power, voltage, and current must
be shown. The answer is C
The combination of variables is (kg*m^2/s^3) corresponds to a watt (i.e power)
The answer is D
A force to rotate, turn, or twist a rigid body a pivot point. Also called torque and
are vectors.

Term
Why is excess air required in combustion?
A) it allows the reaction to occur stoichiometrically
B) it reduces air pollution
C) it reduces the heat required
D) it allows complete combustion

Bases have a bitter taste, unlike acids which have a sour taste. The answer is D
A deliquescent substance melts or dissolves by absorbing moisture from the air.
The answer is D
Excess air is required for complete combustion to occur. The answer is D
Elements with smaller radii are more stable than those with larger radii. Elements
increase their stability toward the right side of the periodic table. The answer is B

For a body resting on a horizontal surface, the normal force is the
1) weight of the body
Fx=Vcos(theta)
N=mg
Rh= area in flow/ wetted perimeter
