Which of these is the correct constant declaration for the gravitational constant which is equal to 1.07 times 10 to the negative 9th power in feet cubed per pound second squared?

Const Gravity = 1.07 * 10 ^ -9 $$ft^3$$/lb*$$sec^2$$

Constant Gravity = -1.07 x $$10^9$$

Which is the appropriate constant declaration for the weight of the Earth in pounds?

const WEIGHTEARTH = 1.$$315E10^25$$

WeightEarth Const = 1.315 * 10 ^ -25

constant WeightEarth = 1.315E-25

Which is the correct line to use for the beginning of the For Next loop that generates the elevations from 0 to 20000 feet above the Earth's surface for elevations of 1000 feet increments?

For Elevation = 0 To 20000 Step 1000

For Acceleration = 1 To 1000 Step 20000

Which is the correct assignment statement for calculating the acceleration?

Acceleration = GRAVITY * WEIGHTEARTH / (RADIUSEARTH + Elevation) ^ 2

Acceleration = Gravity * WeightEarth / RadiusEarth + Elevation ^ 2

- Constant
- Constant
- Const
Correct Answer

A. Const

Explanation

Starts with a capital C. Const

3.

Which is the appropriate constant declaration for the weight of the Earth in pounds?
- Const WEIGHTEARTH = 1.315E10^25
- WeightEarth Const = 1.315 * 10 ^ -25
- Const WEIGHTEARTH = 1.315e25
- Constant WeightEarth = 1.315E-25
Correct Answer

A. Const WEIGHTEARTH = 1.315e25

Explanation

All capitals and exponential notation.

Rate this question:
4.

What line of code will put the cursor on the Clear command button?
- CmdClear.SetFocus
- MnuClear.SetFocus
- Clear.SetFocus
- CmdClear.Focus
Correct Answer

A. CmdClear.SetFocus

Explanation

You look where the cursor is, so the code for putting the cursor somewhere is done with the name of the object followed by .SetFocus

Rate this question:
5.

Which is the correct line to use for the beginning of the For Next loop that generates the elevations from 0 to 20000 feet above the Earth's surface for elevations of 1000 feet increments?
- For Elevation = 1 To 20000
- For Elevation = 0 To 1000
- For Acceleration = 1 To 1000 Step 20000
- For Elevation = 0 To 20000 Step 1000
Correct Answer

A. For Elevation = 0 To 20000 Step 1000

Explanation

The directions call for the elevations to be feet above the Earth's surface from 0 to 20000 feet in 1000 foot increments. Units are not used in the For Next loop. The phrase in 1000 foot increments means that the step is 1000. No commas are used. The variable after For and after Next is Elevation.

Rate this question:
6.

Which is the correct assignment statement for calculating the acceleration?
- Acceleration = GRAVITY * WEIGHTEARTH / (RADIUSEARTH + Elevation) ^ 2
- A = G * W / R + E ^ 2
- Acceleration = Gravity * WeightEarth / RadiusEarth + Elevation ^ 2
- Acceleration = (Gravity * WeightEarth / RadiusEarth + Elevation) ^ 2
Correct Answer

A. Acceleration = GRAVITY * WEIGHTEARTH / (RADIUSEARTH + Elevation) ^ 2

Explanation

The correct assignment statement for calculating the acceleration is "Acceleration = GRAVITY * WEIGHTEARTH / (RADIUSEARTH + Elevation) ^ 2." This formula correctly calculates the acceleration by multiplying the gravity (GRAVITY) by the weight of the Earth (WEIGHTEARTH), and then dividing it by the sum of the radius of the Earth (RADIUSEARTH) and the elevation, all raised to the power of 2.

Rate this question:
7.

What is the best name for the menu item with the word Gravity?
- LblGravity
- CmdGravity
- MnuGravity
- TxtGravity
Correct Answer

A. MnuGravity

Explanation

mnu is the 3-letter prefix for menu items.

Rate this question:
8.

Which is the correct syntax for the constant definition for the radius of the Earth in feet?
- Ft Radius_Earth = 20,882,400
- Const RADIUSEARTH = 20882400
- Const RadiusEarth = 20,882,400 ft
- Constant RADIUSEARTH = 20882400 FEET
Correct Answer

A. Const RADIUSEARTH = 20882400

Explanation

Do NOT include units. Do not include commas.

Rate this question:
9.

Since the elevations are going to be provided by a For Next loop and will be from 0 to 20,000 feet above the Earth's surface in 1000 feet increments, how should the variable Elevation be declared?
- Dim Elevation As Single
- Dim Elevation As String
- Dim Elevation As Integer
- Const Elevation = 20000
Correct Answer

A. Dim Elevation As Integer

Explanation

Only integers are needed because the elevations will be 0, 1000, 2000, 3000, 4000, etc up to 20000.

Rate this question:
10.

Which is the correct declaration for a variable that will hold the various results as they determined in the For Next loop?
- Dim ResultString As Integer
- Dim ResultString As Single
- Const ResultString = 32.2
- Dim ResultString As String
Correct Answer

A. Dim ResultString As String

Explanation

Look at the ResultString.frm directions as a guide. ResultString is a concatenation of values and spaces put into a string variable.

Rate this question:
11.

If the result string is made up of a concatenation of values of variables and space and then added to the listbox, which of these lines of code would be appropriate for displaying the output to the listbox?
- ResultList.AddItem ResultString
- ResultList.Clear ResultString
- ResultString.AddItem ResultList
- ResultString.AddItem Sum
Correct Answer

A. ResultList.AddItem ResultString

Explanation

ResultList is the name of the ListBox where the results are being displayed. .AddItem is used with ListBoxes. The value of the variable ResultString is being added to the ListBox each time through the loop.

Rate this question:
12.

What line of code tells the computer when to increment the elevation and when to repeat the loop?
- Next Loop
- Next Elevation
- End If
- End Loop
Correct Answer

A. Next Elevation

Explanation

Every For has its Next. The variable and For and its corresponding Next, must be the same.

Rate this question:
13.

What is the standard way to write constants in Visual Basic?
- All capital letters
- All lowercase letters
- First letter capital and the rest lowercase
- Capitals for each new word
Correct Answer

A. All capital letters

Explanation

All caps make constants look different from variables.

Rate this question:
14.

Since the acceleration is going to be calculated by the program, its variable must also be declared. The sample output shows values such as 32.26627 and 32.22921 as accelerations; therefore, which is the best declaration for the acceleration variable?
- Dim Acceleration As Integer
- Dim Acceleration As String
- Const Acceleration As Single
- Dim Acceleration As Single
Correct Answer

A. Dim Acceleration As Single

Explanation

Single is needed for decimals.
