charge?
A. It varies directly as the distance to the charge.
B. It varies inversely as the distance to the charge.
C. It varies directly as the square of the distance to the charge.
D. It varies inversely as the square of the distance to the charge. -CORRECTANSWER
D. It varies inversely as the square of the distance to the charge.
As a professional engineer originally licensed 30 years ago, you are asked to evaluate a
newly developed computerized control system for a public transportation system. You
may accept this project if:
A. you are competent in the area of modern control systems
B. you do not live in the jurisdiction where the transportation system is being installed
C. your original area of specialization was in transportation systems
D. you have regularly attended meetings of a professional engineering society -
CORRECTANSWER A. you are competent in the area of modern control systems
,The SI system uses (1) for mass and (2) for weight (force). -CORRECTANSWER 1)
Kilograms
2) Newtons
Mass is a constant property of an object where (1) varies with gravitational field. -
CORRECTANSWER 1) weight
What is a metric ton? -CORRECTANSWER A metric ton also known as a tonne, is
1000 kg
What is a kip? -CORRECTANSWER The abbreviation "kip" is used for "kilo-pound":
1000 pounds of force
What basic SI unit is equal to kg*m^2/s^2 -CORRECTANSWER 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 -CORRECTANSWER The main property of an identity matrix is that AI=A.
Therefore, choice (d) is false
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 -CORRECTANSWER 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 CORRECTANSWER is D
What is a matrix? -CORRECTANSWER 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? -CORRECTANSWER 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.
, True or False: Addition and subtraction of two matrices are possible only if both
matrices have the same size and shape? -CORRECTANSWER True
What is an identity matrix? -CORRECTANSWER 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) -CORRECTANSWER 1)
identity matrix
A (1) has only magnitude. Mass, enthalpy, density, and speed are examples of this. -
CORRECTANSWER 1) scalar
Force, momentum, displacement, and velocity are examples are (1). A (1) has a specific
direction and magnitude. -CORRECTANSWER 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
