ANS:A - Only assumption I is implicit

Explanation: The statement indicates the impossibility of phone contact from Karshik. Thus, the fact in I may be assumed from the given statement. So, I is implicit However, II indicates difficulty, not the impossibility of contact as is indicated in the statement. So, II is not implicit.

ANS:A - 5 6

No answer description is available. Let's discuss.

ANS:D - 6t + 2

x=t^2(t+1)=t^3+t^2.
Differentiating on both side
w.r.t. t => dx/dt=3t^2+2t then double differentiation: d^2x/dt^2=6t+2. x = t2(t+1).
x = t3+t2.

dx/dt = 3t2+2t.
d2x/dt2 = 6t+2.

This is the required answer of the acceleration but acceleration negative sign indicated.

ANS:A - cache

MSD (Microsoft Diagnostics) was a software tool developed by Microsoft to assist in the diagnostics of 1990s-era computers. Users primarily deployed this tool to provide detailed technical information about the user's software and hardware and to print the gathered information, usually for use by support technicians in troubleshooting and resolving problems.
msd.exe Is A Process Used To Determine What Serial Ports Are Installed In Your Computer.

MSD provided technical information:

computer brand and processor information
memory (total, EMS, and XMS)
video (type such as VGA and manufacturer)
network
operating-system versions
type of mouse (if installed)
disk drives (and partitions), excluding CD-ROM drives etc.
LPT ports
COM ports
IRQ status
TSR programs
device drivers
other adapters.

ANS:B - electrostatic precipitator

The most suitable equipment for removing fine dust particles (< 1 micron diameter) from air below its dew point is a wet scrubber.

Explanation:

• Wet Scrubber: A wet scrubber is an air pollution control device that uses a liquid (often water) to remove pollutants from air streams. Fine dust particles, including those smaller than 1 micron in diameter, can be effectively captured by wet scrubbers through mechanisms such as absorption, impaction, and condensation.
• Operation: In a wet scrubber:
  • Air laden with dust enters the scrubber and passes through a wetted surface or spray where the dust particles come into contact with water.
  • Fine particles adhere to the water droplets through condensation or absorption processes.
  • The dust-laden water is collected and treated separately, while the cleaned air is discharged.
• Advantages:
  • Effective for capturing fine particulate matter, including particles smaller than 1 micron, due to the intimate contact between particles and water.
  • Suitable for applications where air may be below its dew point, as the wet scrubbing process can handle moisture in the air stream.
• Other Options:
  • Bag Filter: Typically used for capturing larger particles and may not be as effective for very fine particles (< 1 micron) or for conditions where moisture is present.
  • Electrostatic Precipitator: Effective for removing larger particles and some smaller particles through electrostatic attraction, but may not be as efficient for particles < 1 micron or in moist air conditions.
  • Cyclone Separator: Primarily used for larger particles and may not effectively capture particles < 1 micron or handle conditions below the dew point.
