Answer:

120 Hz

Explanation:

Given that a 60 Hz sinusoidal voltage is applied to the input of a half-wave rectifier, what will be the output frequency ?

Ideally, the supply frequency will be equal to the ripple frequency.

But in a half - way rectifier, the out put frequency is twice the input sinusoidal voltage frequency.

The output frequency = 2 × 60

Output frequency = 120 Hz

Therefore, When a 60 Hz sinusoidal voltage is applied to the input of a half-wave rectifier, the output frequency is 120 Hz.

Estimate the theoretical fracture strength of a brittle material if it is known that fracture occurs by the propagation of an el

Allisa [31]

Answer:

theoretical fracture strength = 16919.98 MPa

Explanation:

given data

Length (L) = 0.28 mm = 0.28 × 10⁻³ m

radius of curvature (r) = 0.002 mm = 0.002 × 10⁻³ m

Stress (s₀) = 1430 MPa = 1430 × 10⁶ Pa

solution

we get here theoretical fracture strength s that is express as

theoretical fracture strength = $s_{0} \times \sqrt{\frac{L}{r} }$ .............................1

put here value and we get

theoretical fracture strength = $1430 \times 10^6\times \sqrt{\frac{0.28\times 10^{-3}}{0.002\times 10^{-3}} }$

theoretical fracture strength = $16919.98 \times 10^6$

theoretical fracture strength = 16919.98 MPa

A piston-cylinder device initially at 0.4-m3 contains nitrogen gas at 600 kPa and 300 K. Now the gas is compressed isothermally

madreJ [45]

Answer:

W = 166.35 KJ

Explanation:

P₁ = 600 KPa

V₁ = 0.4 m³

V₂ = 0.2 m³

T = 300 K

W = ?

We can find the solution from the standard relation for work in an isothermal process

W = -n*R*T*Ln (Vf / Vi)

We know that

n*R*T = P*V ⇒ P₁*V₁ = P₂*V₂ = n*R*T = 600 *0.4 = 240

Now, we use the equation

W = -n*R*T*Ln (Vf / Vi) = - P₁*V₁*Ln (Vf / Vi)

⇒ W = -240*Ln (0.2 / 0.4) = 166.35 KJ
