140 is the velocity because you need to multiply 40×2.5
Answer:
1
Explanation:
The ratio of their nuclear densities is 1, as nuclear density is constant for all nuclei.
Answer:
1) The angle of deflection will be less than 45° ( C )
2) The angle of deflection will be greater than 45° but less than 90° ( E )
Explanation:
1) Assuming that the force applied has a direction which is perpendicular to the Earth's magnetic field
∴ Fearth > Fapplied hence the angle of deflection will be < 45°
2) when the Fearth < Fapplied
the angle of deflection will be : > 45° but < 90°
Answer:
The gauge pressure is 1511.11 psi.
Explanation:
Given that,
Flow rate = 94 ft³/min
Diameter d₁=3.3 inch
Diameter d₂ = 5.2 inch
Pressure P₁= 15 psi
We need to calculate the pressure on other side
Using Bernoulli equation
We know that,
Where, V = volume
v = velocity
A = area
Put the value of v into the formula
Put the value into the formula
We need to calculate the gauge pressure
Using formula of gauge pressure
Put the value into the formula
Hence, The gauge pressure is 1511.11 psi.
