ANS:A - Only assumption I is implicit

Explanation: The fact that patient's condition would improve after the operation clearly implies that the patient can be operated upon in this condition. So, I is implicit.

ANS:C - Contents of the two objects created will be exactly same.

No answer description is available. Let's discuss.

ANS:B -

Upward tension = m(g+a)
here given downward tension = 2t = m(g-a).
t = 2m(g-a) = m(g+a)
= 2mg + ma = mg - ma
= mg = 3ma.
g = 3a.
a = g/3.

ANS:B - 25Mhz

The number of bits processed at one time is the processor's register size (word size). Intel's 8086 processor's register size is 16 bits, or 2 bytes. Today's CPUs have register sizes of 64 or 128 bits.
Buses

Processors operate on 1s and 0s. Processors operate on 1s and 0s. The 1s and 0s must travel from one place to another inside the processor, as well as outside to other chips. To move the 1s and 0s around, electronic lines called a bus are used. The electronic lines inside the CPU are known as the internal data bus or system bus. In the 8086, the internal data bus comprises 16 separate lines, with each line carrying one 1 or one 0. The word size and the number of lines for the internal data bus are equal. The 8086, for example, has a 16-bit word size, and 16 lines carry 16 bits on the internal data bus. In today\'s processors, 64 or 128 internal data bus lines operate concurrently.

For a CPU to communicate with devices in the outside world, such as a printer, the 1s and 0s travel on the external data bus. The external data bus connects the processor to adapters, the keyboard, the mouse, the hard drive, and other devices. An external data bus is also known as an external data path. You can see the external data lines by looking between the expansion slots on the motherboard. Some solder lines between the expansion slots are used to send data out along the external data bus to the expansion slots. Today\'s processors have 64- and 128-bit external data paths. Figure 3.3 shows the internal and external data buses.

ANS:A - calls for relatively less energy for the smaller product particles, than does the Rittinger law.

The correct statement regarding Bond's crushing law is: "States that the work required for crushing is proportional to the square root of the volume to surface ratio of the product."

Explanation:

• Bond's Crushing Law: Bond's law states that the work required to form particles of any size from very large feed is proportional to the square root of the volume to surface ratio of the product particles.
• Key Points:
  • Bond's law contrasts with Rittinger's law, which states that the work required is proportional to the new surface area created (not mentioned in the options provided).
  • Bond's law is considered more realistic for estimating the energy requirements of commercial crushers compared to Rittinger's law, especially in applications where particles are reduced to smaller sizes.
• Options Analysis:
  • The statement about Bond's law being less realistic in estimating power requirements is not accurate; it is generally considered more applicable than Rittinger's law for industrial crushing operations.
  • The statement that Bond's law calls for relatively less energy for smaller product particles than Rittinger's law is not directly supported by the principles of Bond's law.
  • Bond's law does not explicitly state that the work required is proportional to the new surface created; rather, it focuses on the relationship involving the volume to surface ratio of the product.

ANS:D - Kelvin Kiptum

Kenyan runner Kelvin Kiptum broke the marathon world record on October 8, 2023, at the Chicago Marathon, with a time of 2:00:35. He beat the previous record, set by Eliud Kipchoge in 2022, by more than 30 seconds.
