<h3>What is a semiconductor?</h3>

A semiconductor is a device whose conductivity lies between the conductivity of the conductors and the insulators.

Due to the inclusion of an impurity or temperature effects, a solid substance with conductivity between that of an insulator and that of most metals. Semiconductor devices, particularly silicon devices, are key components of most electronic circuits.

Zener diode:-

One AA battery in a flashlight stores 9400 J. The three LED flashlight bulbs consume 0.5 W. How many hours will the flashlight l

Effectus [21]

Answer:

time = 5.22 hr

Explanation:

Given data:

Energy of battery = 9400 J

Power consumed by three led bulb is 0.5 watt

we know Power is give as

$Power = \frac{ energy}{time}$

plugging all value and solve for time

$time = \frac{energy}{power}$

$time = \frac{9400}{0.5}$

time = 18,800 sec

in hour

1 hour = 3600 sec

therefore in 18,800 sec

$time = \frac{18800}{3600} = 5.22 hr$

The velocity of a particle which moves along the s-axis is given by v = 2-4t+5t^(3/2), where t is in seconds and v is in meters

Brut [27]

Answer:

a) s = 42 m

b) V = 26 m/s

c) a = 11 m/s²

Explanation:

The velocity(V) = 2 - 4t + 5t^3/2 where t is in seconds and V is in m/s

a) To get the position, we have to integrate the velocity with respect to time.

We get the position(s) from the equation:

$V=\frac{ds}{dt}$

$ds=Vdt$

Integrating both sides,

$s=\int\ {V} \, dt$

$s=\int\ {(2-4t+5t^{\frac{3}{2} }) \, dt$

Integrating, we get

$s=(2t-2t^{2} +2t^{\frac{5}{2} }+c)m$

But at t=0, s(0) = 2 m

Therefore,

$s(0)=2(0)-2(0)^{2} +2(0)^{\frac{5}{2} }+c$

$2=0+0+0+c$

c = 2

Therefore

$s=(2t-2t^{2} +\frac{10}{5}t^{\frac{5}{2} }+2)m$

When t = 4,

$s=2(4)-2(4)^{2} +2(4)^{\frac{5}{2} }+2$

$s=8-32+64+2$

s = 42 m

At t= 4s, the position s = 42m

b) The velocity equation is given by:

$V=(2-4t+5t^{\frac{3}{2} })m/s$

At t = 4,

$V=2-4(4)+5(4)^{\frac{3}{2} }$

V = 2 - 16 + 40 = 26 m/s

The velocity(V)at t = 4 s is 26 m/s

c) The acceleration(a) is given by:

$a=\frac{dv}{dt}$

$a=\frac{d}{dt}(2-4t+5t^{ \frac{3}{2}})$

Differentiating with respect to t,

$a=-4+\frac{15}{2}t^{\frac{1}{2} }$

$a=(-4+\frac{15}{2}t^{\frac{1}{2} })m/s^{2}$

At t = 4 s,

$a=-4+\frac{15}{2}(4)^{\frac{1}{2} }$

$a=-4+15$

a = 11 m/s²
