Question 1

The two aspects of a vector,length and ____,are exactly the important aspects of force.
A) direction
B) velocity
C) acceleration
D) normal distribution

Accepted Answer

The two aspects of a vector are its length (magnitude) and direction. Similarly, force also has these two aspects - its magnitude (or strength) and direction. Therefore, the best choice is option A) direction.

Question 2

Excel provides the ability to "____" a cell,so that Excel will not try to perform iteratively with it.
A) delimit
B) freeze
C) delete
D) chart

Accepted Answer

Freezing a cell in Excel means to keep it in a fixed position while scrolling through the rest of the worksheet. This has nothing to do with delimiting, deleting, or charting a cell.

Question 3

When an object is falling in air,or any other material like water or quicksand,the speed continuously increases.

Accepted Answer

The speed increases only up to a point where the drag force equals the gravitational force, leading to a constant velocity known as terminal velocity.

Question 4

Pie,bar,and column charts can represent two- and three-dimensional data.

Accepted Answer

Pie, bar, and column charts are common ways of representing two- and three-dimensional data in a visual form. They can show numerical data in an easy-to-understand way, and are useful for comparing different categories or values.

Question 5

Accepted Answer

The answer of A(n)____________________ coordinate system is typically the most...

Question 6

A bin definition is not necessary for making a histogram.

Accepted Answer

A bin definition is necessary for making a histogram, as it determines the range of values that will be grouped together and represented by each column in the graph. Without binning, the data would not be properly organized and displayed in the histogram.

Question 7

The ____________________ of a material is its mass divided by its volume.

Accepted Answer

The answer of The ____________________ of a material is its...

Question 8

According to Newton's second law,the ____ of an object is equal to the force imparted on an object divided by its mass.
A) position
B) momentum
C) acceleration
D) velocity

Accepted Answer

Newton's second law states that the acceleration of an object is directly proportional to the force acting on it and inversely proportional to its mass. Therefore, the correct answer is option C, acceleration.

Question 9

The natural exponential function uses the number ____ as the base.
A) 1
B) e
C) pi
D) 10

Accepted Answer

The natural exponential function is defined as e^x, where e is a mathematical constant approximately equal to 2.71828. Therefore, the number e is used as the base for the natural exponential function.

Question 10

When items in a structure are not moving,the sum of all the forces must equal one.

Accepted Answer

When items in a structure are not moving, the sum of all the forces must equal zero, indicating a state of equilibrium.

Question 11

Two typical units of ____________________ velocity are radians/second (rad/s)and degrees/second (deg/s).

Accepted Answer

The answer of Two typical units of ____________________ velocity are...

Question 12

There are ____$\pi$ radians in a circle.
A) 1/2
B) 1
C) 2
D) 4

Accepted Answer

There are always $2\pi$ radians in a circle, regardless of its size or orientation. Therefore, the answer is C) 2 radians.

Question 13

Radians per second (rad/s)are units for ____.
A) angular velocity
B) angle
C) torque
D) angular variation

Accepted Answer

Radians per second (rad/s) are units for angular velocity, which is the rate of change of angular displacement with respect to time. It is commonly used in physics and engineering to describe rotational motion.

Question 14

As the name implies,a ____ is a kind of history of data.
A) storigram
B) trend graph
C) histogram
D) past chart

Accepted Answer

A histogram is a visual representation of data that shows the distribution of numerical data. It is a type of graph that shows the frequency or number of occurrences of data within specific intervals or bins. The histogram is a useful tool for analyzing trends and patterns in data over time, and can help identify outliers and other anomalies that may be of interest to researchers or analysts. The other choices are not commonly used terms to refer to a history of data and do not accurately describe the function of a histogram.

Question 15

The equation for a ____ centered at the origin in Cartesian coordinates is x² + y² = R². A) circle B) parabola C) square D) line

Accepted Answer

The equation represents a circle with radius R centered at the origin. The terms involving x and y are both squared, which is a characteristic of a circle's equation in Cartesian coordinates. The other choices (parabola, square, line) do not have this characteristic equation.

Question 16

A(n)____________________ is the amount a line needs to be rotated to bring the line into coincidence with another line.

Accepted Answer

The answer of A(n)____________________ is the amount a line needs...

Question 17

In a(n)____ plot,the real numerical values are used in the plot.
A) relative
B) pie
C) accurate
D) absolute

Accepted Answer

Absolute plots use actual numerical values to represent data accurately, without any relative or proportional adjustments.

Question 18

Torque is the rotational equivalent to acceleration.

Accepted Answer

Torque is the rotational equivalent to force, not acceleration.

Question 19

____________________ is the rate of change of velocity with time.

Accepted Answer

The answer of ____________________ is the rate of change of...

Question 20

Objects falling freely toward Earth,neglecting air resistance,are governed by three equations,including the following: V = gt + ____. A) gt² B) V_initial C) S_initial D) tV_initial

Accepted Answer

The equation V = gt + Vi (where Vi is the initial velocity) represents the velocity of an object falling freely towards Earth without taking air resistance into account. Option B is the closest to this equation, with the initial velocity represented by U1B0.
