How much computer memory (in bytes) in minimum would be required to store 10 seconds of a sensor signal sampled by a 12-bit A/D converter operating at a sampling rate of 5 kHz?
Answers
Answer:
73.24 K byte
Explanation:
Assuming that
N = total number of samples
N = 10 * 5kHz
N = 50*10^3
Also, the total number of bits, T
T = 12 * N
T = 12 * 50*10^3
T = 600 * 10^3
And then, finally, the total number of byte,
B = 600*10^(3/8)
B = 75*10^3 byte
75*10^3 byte = 75*10^3/1024 kilo byte
And on converting to decimal, we will have
= 73.24 K byte
Therefore, the memory required = 73.24 K byte

(c)- Elastic modulus
Explanation:
We know that in tensile test we measure the properties of the material like yield strength,ultimate tensile strength ,Poisson ratio.
In tensile test
σ = ε E
Where σ is the stress
ε is the strain.
E is the elastic modulus.
Now for shear tress
τ = Φ G
Where τ the shear stress
Φ is the shear strain.
G is the shear modulus.
So we can say that Shear modulus is analogous to Elastic modulus.

A. The heat transfer rate from natural gas is 2105.26 MW
B. The heat transfer rate to river is 1305.26 MW
Efficiency formula
Efficiency = (power output / power input) × 100
A. How to determine the heat transfer from natural gas
- Efficiency = 38%
- Power output = 800 MW
- Power input =?
Power input = Power input / efficiency
Power input = 800 / 38%
Power input = 800 / 0.38
Power input = 2105.26 MW
Thus, the heat transfer from natural gas is 2105.26 MW
B. How to determine the heat transfer to the river
- Total heat = 2105.26 MW
- Heat used by plant = 800 MW
- Heat to the river =?
Heat to the river = 2105.26 – 800
Heat to the river = 1305.26 MW

Answer:
heat transfer from natural gas is 2105.26 MW
heat transfer to river is 1305.26 MW
Explanation:
given data
power output Wn = 800 MW
efficiency = 38%
solution
we know that efficiency is express as
......................1
put here value we get
38% =
Qin = 2105.26 MW
so heat supply is 2105.26
so we can say
Wn = Qin - Qout
800 = 2105.26 - Qout
Qout = 2105.26 - 800
Qout = 1305.26 MW
so heat transfer from natural gas is 2105.26 MW
and heat transfer to river is 1305.26 MW

Answer:
a.) Time = 17.13 seconds
b.) 31.88 m
c.) V = 11.18 m/s
d.) V = 7.1 m/s
Explanation:
The initial velocity U of the automobile is 15.65 m/s.
At the instant that the two vehicles are abreast of each other, the police car starts to pursue the automobile with initial velocity U = 0 at a constant acceleration of 1.96 m/s². Because the police is starting from rest.
For the automobile, let us use first equation of motion
V = U - at.
Acceleration a is negative since it is decelerating with a = 3.05 m/s² . And
V = 0.
Substitute U and a into the formula
0 = 15.65 - 3.05t
15.65 = 3.05t
t = 15.65/3.05
t = 5.13 seconds
But the motorist noticed the police car in his rear view mirror 12 s after the police car started the pursuit and applied his brakes and decelerates at 3.05 m/s².
The total time required for the police car to overtake the automobile will be
12 + 5.13 = 17.13 seconds.
b.) Using the third equation of motion formula for the police car at V = 11.18 m/s and a = 1.96 m/s²
V^2 = U^2 + 2aS
Where S = distance travelled.
Substitute V and a into the formula
11.18^2 = 0 + 2 × 1.96 ×S
124.99 = 3.92S
S = 124.99/3.92
S = 31.88 m
c.) The speed of the police car at the time it overtakes the automobile will be in line with the speed zone which is 11.18 m/s
d.) That will be the final velocity V of the automobile car.
We will use third equation of motion to solve that.
V^2 = U^2 + 2as
V^2 = 15.65^2 - 2 × 3.05 × 31.88
V^2 = 244.9225 - 194.468
V = sqrt( 50.4545)
V = 7.1 m/s
