Indentify the following:
- It uses Integrated Circuit assemblies as memory to store data persistently.
- It has no moving mechanical (D) MI of these components and it is typically more resistant to physical shock.

  1. Hard disk drive

  2. Solid-state drive

  3. Magnetic tape drive

  4. All of these

B Correct answer
Explanation

A Solid-State Drive (SSD) uses NAND flash memory (integrated circuits) to store data persistently without moving parts, making it durable against physical shock.

In an ideal mechanical the output energy is :

  1. more than input energy

  2. equal to input energy

  3. less than input energy

  4. infinite compared to input energy

A Correct answer
Explanation

Ideal machine. The term ideal machine refers to a hypothetical mechanical system in which energy and power are not lost or dissipated through friction, deformation, wear, or other inefficiencies.The mechanical efficiency of a simple machine is calculated by dividing the actual power output by the ideal power output.

For every turn of a screw jack:

  1. object would be lifted up by the distance between two successive threads

  2. object will be lifted up by half the distance between two successive threads

  3. object will be lifted up by twice the distance between two successive threads

  4. none of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A screw jack converts rotational motion into linear motion. For one full rotation of the handle, the load is lifted by a distance equal to the pitch of the screw, which is the distance between two successive threads.
