The SI system uses (1) for mass and (2) for weight (force). - 1) Kilograms
,FE Electrical Exam review 2024
2) Newtons
Mass is a constant property of an object where (1) varies with gravitational field. -
1) weight
What is a metric ton? - A metric ton also known as a tonne, is 1000 kg
What is a kip? - The abbreviation "kip" is used for "kilo-pound": 1000 pounds of
force
What basic SI unit is equal to kg*m^2/s^2 - Kinetic energy is calculated in SI units
as (1/2)mv^2, with units of the joule
Which of the following is false for an identity matrix, I?
(a) I is a square matrix
(b) All entries in I are zero, except the entries whose row and column numbers are
equal
(c) all nonzero entries are equal to 1.
(d) AI=A^-1 - The main property of an identity matrix is that AI=A. Therefore,
choice (d) is false
,FE Electrical Exam review 2024
Which of the following statements is true for a power series with the general term
aix^i?
I. An infinite power series converges to for x<1
II. Power series can be added together or subtracted within their interval of
convergence.
III. Power series can be integrated within their interval of convergence
(a) I only
(b) II only
(c) I and II
(d) II and III - Power series can be added together, subtracted from each other,
differentiated, and integrated within their interval of convergence. The interval of
convergence is -1 < x <1. Therefore the answer is D
What is a matrix? - A matrix is an ordered set of entries arranged rectangularly
and set off by brackets.A matrix itself has no particular value, it is merely a
convenient method of representing a set of numbers.
When can you multiple two matrices together? - A matrix can be multiplied by
another matrix, but only if the left-handed matrix has the same number of
columns as the right-hand matrix has rows.
, FE Electrical Exam review 2024
True or False: Addition and subtraction of two matrices are possible only if both
matrices have the same size and shape? - True
What is an identity matrix? - The identity matrix is a diagonal matrix, meaning that
it is a square matrix with all zero entries except for the aij entries, for which i=j. All
nonzero entries are equal to one, and the matrix has the property that AI=IA=A
The product of a Matrix A and its inverse, A^-1 , is the (1) - 1) identity matrix
A (1) has only magnitude. Mass, enthalpy, density, and speed are examples of this.
- 1) scalar
Force, momentum, displacement, and velocity are examples are (1). A (1) has a
specific direction and magnitude. - 1) vectors
What is t-test (based on student's t-distribution) useful for?
(a) testing for distribution of outcomes to see if they come from a normal
distribution
(b) determining if the functional is symmetric about zero
(c) comparing values about the mean
