ANS:E - Both I and II are implicit

Explanation: The PTA is an association which would surely reflect the parents' interests and act to get them fulfilled. So, both I and II are implicit.

ANS:B - A value 1 will be assigned to d.

Sample Program:

bool falseFlag = false;
bool trueFlag = true;

Console.WriteLine('{0} converts to {1}.', falseFlag,
                  Convert.ToInt32(falseFlag));
Console.WriteLine('{0} converts to {1}.', trueFlag,
                  Convert.ToInt32(trueFlag));

The example displays the following output:

       False converts to 0.
       True converts to 1.

ANS:B -

We all know the equation of a parabola given by Y^2= 4aX the centre of gravity for y coordinate is given by y = integral of y^2/2 from 0 to a divided by the integral of y from 0 to a.

After doing the calculations the answer will be 3a/4. Consider it to a triangle instead of a parabola, then the distance of C.G. from Y-axis would be 2*a/3=0.66*a.

But now, it's a parabola, so the centroid has shifted away from Y-axis, so the answer should be > 0.66*a.

Now, option A gives 0.25*a which is less than 0.66*a, so option A eliminated.
option C is eliminated since the distance is asked from Y-axis and not X-axis.
Option D = 0.3*a<0.66*a, so eliminated,
Option E = 0.6*a<0.66*a, so eliminated.
Hence, correct answer is option B = 0.75*a.

ANS:D - 13

The answer is wrong!

Rivet value is taken as minimum value of Shearing, Bearing and tearing!
No of rivets = Force/Rivet value.
Then the answer is 10.21.

ANS:B - Erratic ribbon advancement

No answer description is available.

ANS:B - Rotary disc filter

Among the options provided, the Rotary disc filter is a type of vacuum filter.

Explanation:

• Vacuum Filter: A vacuum filter operates by applying a vacuum (reduced pressure) to assist in the filtration process, separating solids from liquids. This method is commonly used in various industrial processes where efficient separation and drying of solids are required.
• Types of Vacuum Filters:
  • Rotary Disc Filter: This type of filter consists of a series of rotating discs covered with filter media. As the discs rotate, they pass through different stages of filtration (vacuum, cake formation, washing, and drying), allowing for continuous operation.
• Other Options:
  • Filter Press: Operates under pressure rather than vacuum. It uses pressure to squeeze out liquid from the filter cake after filtration.
  • Batch Basket Centrifuge: Uses centrifugal force to separate solids from liquids and is not typically classified as a vacuum filter.
  • Tank Filter (Nutsch Filter): Operates under pressure or gravity and does not involve vacuum filtration directly.
