Answer:

The answer 1 is correct.

Explanation:

When a junction called the p-n is forward biased, the capacitance of diffusion will form or structured across depletion layers.

When at a higher frequency or frequencies, the dopants, are vibrated across the metallurgical junction and the doping profiles smooths out.

A 5Kw solar system may produce enough energy to power your home. a)-True b)- False

Minchanka [31]

Answer: True

Explanation:

Yes, it is true that 5 Kw solar system may produce enough energy to power your home as, on an average good quality of 5 KW solar system can produced 22 units per day enough to power all home appliances. As, a 5 KW solar system produced energy is basically depends on the three main factor that are:

Quality of the solar panel system.
Location from where the solar system generated its energy.
And also on the positioning of the solar system.

Heat in the amount of 100 KJ is transferred directly from a hot reservoir at 1200 K to a cold reservoir at 600K.Calculate the en

Lina20 [59]

Answer:

0.0833 k J/k

Explanation:

Given data in question

total amount of heat transfedded (Q) = 100 KJ

hot reservoir temperature R(h) = 1200 K

cold reservoir temperature R(c) = 600 k

Solution

we will apply here change of entropy (Δs) formula

Δs = $\frac{Q}{R(h)}+\frac{Q}{R(c)}$

Δs = $\frac{-100}{1200}+\frac{100}{600)}$

Δs = $\frac{1}{12}$

Δs = 0.0833 K J/k

this change of entropy Δs is positive so we can say it is feasible and

increase of entropy principle is satisfied

A power screw is 30 mm in diameter and has a thread pitch of 5 mm. Find the thread depth, the thread width, the mean and root di

ankoles [38]

Answer:

thread depth = 2.5 mm

thread width = 2.5 mm

mean diameter = 27.5 mm

root diameter = 25 mm

lead of screw = 5 mm

Explanation:

given data

power screw diameter D = 30 mm

thread pitch P = 5 mm

solution

First, we get here thread depth fr square thread

thread depth = $\frac{P}{2}$ ......................1

thread depth = $\frac{5}{2}$

thread depth = 2.5 mm

and

thread width for square thread

thread width = $\frac{P}{2}$ ......................2

thread width = $\frac{5}{2}$

thread width = 2.5 mm

and

mean diameter is

mean diameter = D - $\frac{P}{2}$ ................3

mean diameter = 30 - $\frac{5}{2}$

mean diameter = 27.5 mm

and

root diameter is

root diameter = D - P ....................4

root diameter = 30 - 5

root diameter = 25 mm

and

lead of screw for single thread so n = 1

so lead of screw = 1 × 5

lead of screw = 5 mm
