Answer:
B) 2.22
Explanation:
In a first step, the system will look in cache number 1. If it is not found in cache number 1, then the system will look in cache number 2. Finally (if not in cache 2 also) the system will look in main memory.
The average access time will take into consideration success in cache 1, failure in cache number 1 but success in cache number 2, failure in cache number 1 and 2 but success in main memory.
Mathematically we can write it into the following equation :
Where AAT is the average access time
H1,H2 and Hm are the hit rate of cache 1,cache 2 and main memory respectively.
T1,T2 and Tm are the access time of cache 1, cache 2 and main memory respectively
Hm = 1
Therefore, option b) is the correct.
Answer:
Yes the statement is true.
Explanation:
Power is defined as the rate at which energy is transferred by an object on account of work done.
Mathematically
An object that does work loses it's energy while an object on which work is done gains energy.
Power is often dependent on the type of energy transfer thus we have Electrical Power, Mechanical Power depending on the type of energy involved in the system.
Concept of power is important since it gives us a measure of how fast energy can be derived to given to a system.
Answer: D
Find the answer in the explanation
Explanation:
Elastic solid will obey Hooke's law which state that the force applied is proportional to the extension provided the elastic limit is not exceeded.
Examples of Newtonian fluid are water, glycerol, honey and all organic solvents
When comparing solids to fluids, the below statement is true
We can therefore conclude that
For elastic solids, stress is linearly related to strain, and for Newtonian fluids, stress is linearly related to strain rate
