I say 1 it seems the most accurate
Answer:
The right solution is "126 Psi".
Explanation:
The given values are:
P₁ = 130 psig
i.e.,
= 
= 
or,
= 
Z₂ = 10ft
= 3.05 m
= 1000 kg/m³
According to the question,
Z₁ = 0
V₁ = V₂
As we know,
⇒ 
On substituting the values, we get
⇒ 
⇒ 
⇒ 
i.e.,
⇒ 
⇒ 
Answer:
1609.1429 rad/sec
Explanation:
By using the relation Angular velocity and frequency as:
Angular velocity (ω) = 2×π×Frequency (ν)
Given the frequency = 256 vibrations per second.
So, Angular velocity can be calculated by using the above formula as:
Angular velocity (ω) = 2×π×Frequency (ν)
⇒Angular velocity (ω) = 2×π×256 rad/ sec
⇒Angular velocity (ω) = 2×(22/7)×256 rad/ sec
<u>⇒Angular velocity (ω) = 1609.1429 rad/ sec</u>
Value of resistor = (12V) /(1.2 x 10^-3A)=10000ohms=10k ohms
