A<u> dynamic caste</u> casting mechanism should be employed if you want to safely change (cast) a pointer type for meaning to a different object in an inheritance hierarchy.

<h3>What is dynamic type casting?</h3>

The dynamic type cast transforms a pointer (or reference) to one class T1 into a pointer (reference) to another class T2 . T1 and T2 must be part of the same order, the classes must be accessible (via public derivation), and the modification must not be ambiguous.

<h3>What is casting mechanism?</h3>

Casting methods involve the use of molten material, usually metal. This molten material is then poured into a mold cavity that takes the form of the completed part. The molten material then cools, with heat naturally being extracted via the mould, until it solidifies into the desired shape.

he timing device in an automobile’s intermittent wiper system is based on an RC time constant and utilizes a 0.500-μF capacitor
Tatiana [17]

Answer:

4000k-ohm to 10,000k-ohm

Explanation:

As we know that time constant for an RC circuit is t=RC

Putting the values of t we can get the range of varaiable resistor as;

t=RC

Putting t=2 we get the first value of the range for the variable resistor

2=R*0.500*10^-6

R=2/(0.500*10^-6)

R=4*10^6

R=4000k-ohm

Now putting t=5 we get the final value for the range of variable resistor

t=RC

5=R*0.500*10^-6

R=5/(0.500*10^-6)

R=10*10^6

R=10,000k-ohm

So variable resistance must be made to vary in the range from 4000k-ohm to 10,000k-ohm

You can copy a selected shape by holding down the ____ key and then dragging the shape.
marshall27 [118]

Answer:

Option A is the correct choice answer for the above question.

Explanation:

In an MS-Powerpoint document, when a user wants to copy the selected shape and drag that shape for use in slides then he needs to--

  1. Select the shape
  2. Press the Ctrl key and
  3. drag that shape on the slide of the powerpoint.

Then the user gets the shape on the slide for their personal use.

The question scenario also suggests the same which is described above. hence Option A is the correct answer while the other is not because--

  • Option B suggests 'ESC' which is used to escape any running program.
  • Option C suggests about ALT key which is of no use for the MS-Powerpoint document.
  • Option D suggests about TAB key which is used to make the space between two texts or diagram.
