The high-pressure air storage tank for a supersonic wind tunnel has a volume of 1000 ft3. If air is stored at a pressure of 30 A
Yuri [45]

Answer:

69.86 slugs

Explanation:

From the ideal gas equation

PV = nRT

n (number of moles) = PV/RT

P is pressure of the gas = 30 atm = 30×101325 = 3,039,750 Pa

V is volume of the gas = 1000 ft^3 = 1000/3.2808^3 = 28.32 m^3

R is gas constant = 8.314 J/mol.K

T is the temperature of the gas = 530 R = 5/9 × 530 = 294.44 K

n = 3,039,750×28.32/8.314×294.44 = 35166.11 mol

mass = n× MW

MW of air = 29 g/mol

mass = 35166.11 × 29 = 1019817.19 g × 0.0685 slug/1000 g = 69.86 slugs

A ball is thrown straight up with a launch of 3 m/s.
PtichkaEL [24]

Explanation:

The ball is in free fall (gravity is the only force acting on the ball), so its acceleration is 9.8 m/s² down during the entire path.

A researcher measures the thickness of a layer of benzene (n = 1.50) floating on water by shining monochromatic light onto the f
NNADVOKAT [17]

Answer:

Explanation:

This problem relates to interference of light in thin films .

The condition of bright fringe in thin films which is sandwitched by two layers of medium having lesser refractive index  is as follows.

2nt = (2n+1) λ / 2  , n is refractive index of thin layer , t is its thickness ,  λ is wavelength of light .

2 x 1.5 t = λ / 2 , if n = 0 for minimum thickness.

2 x 1.5 t = 600 / 2 nm

t = 100 nm .

The moment of inertia is 24.8 kg m^2

Explanation:

The total moment of inertia of the system is the sum of the moment of inertia of the rod + the moment of inertia of the two balls.

The moment of inertia of the rod about its centre is given by

I_r = \frac{1}{12}ML^2

where

M = 24 kg is the mass of the rod

L = 0.96 m is the length of the rod

Substituting,

I_r = \frac{1}{12}(24)(0.96)^2=1.84 kg m^2

The moment of inertia of one ball is given by

I_b = mr^2

where

m = 50 kg is the mass of the ball

r=\frac{L}{2}=\frac{0.96}{2}=0.48 m is the distance of each ball from the axis of rotation

So we have

I_b = (50)(0.48)^2=11.5 kg m^2

Therefore, the total moment of inertia of the system is

I=I_r + 2I_b = 1.84+ 2(11.5)=24.8 kg m^2
