Answer:B
Explanation:
Given
For motor A
Characteristic life(r)=4100 hr
MTTF=4650 hrs
shape factor(B )=0.8
For motor B
Characteristic life(r)=336 hr
MTTF=300 hr
Shape Factor (B)=3
Reliability for 100 hours



For B


B is better for 100 hours
(b)For 750 hours


So here B is more Reliable.
Answer:
t = 2212 years
Explanation:
In radioactive decay processes it is described by the equation
N = N₀
to calculate the activity
= log 2 /λ
λ = log 2 / T_{1/2}
λ = log 2 /5715
λ = 5.267 10⁻⁵
now the amount of carbon 14 is N₀ = 0.1%, the sample contains an amount of N = 0.089%
N / N₀ = e^{-\lambda t}
-λ t = ln N / N₀
t = - 1 /λ ln N /N₀
t = 1 / 5.267 10⁻⁵ ln (0.089 / 0.1)
t = 2,212 10³ years
t = 2212 years

Answer:
7 bits
Explanation:
Given
Instruction Set = 110 operation
Memory unit = 32 bits per word.
We get the required bits by using the following formula
2^n = 110
But 110 is not a factor of 2.
So, we pick the nearest decimal number greater than 110 that is a power of 2.
The number is 128
2^n = 110 becomes
2^n = 128
2^n = 2^7 ---- 2 cancels out
So,
n = 7
Hence, the required number of bits needed for the opcode is 7 bits
