A particle moves along a circular path of radius 300 mm. If its angular velocity is θ = (2t) rad/s, where t is in seconds, deter

uysha [10]

Answer:

4.83m/ $s^{2}$

Explanation:

For a particle moving in a circular path the resultant acceleration at any point is the vector sum of radial and the tangential acceleration

Radial acceleration is given by $a_{radial}=w^{2}$ r

Applying values we get $a_{radial}=(2t)^{2}$ X0.3m

Thus $a_{radial}=1.2t^{2}$

At time = 2seconds $a_{radial}= 4.8m/s^{2}$

The tangential acceleration is given by $a_{tangential} =\frac{dV}{dt}=\frac{d(wr)}{dt}$

$a_{tangential}=\frac{d(2tr)}{dt}$

$a_{tangential}= 2r$

$a_{tangential}=0.6m/s^{2}$

Thus the resultant acceleration is given by

$a_{res} =\sqrt{a_{rad}^{2}+a_{tangential}^{2}}$

$a_{res} =\sqrt{4.8^{2}+0.6^{2} } =4.83m/s^{2}$

A flywheel accelerates for 5 seconds at 2 rad/s2 from a speed of 20 rpm. Determine the total number of revolutions of the flywhe

s344n2d4d5 [400]

Answer:

option (a)

Explanation:

t = 5 sec, α = 2 rad/s^2, f0 = 20 rpm = 20 / 60 rps

Use second equation of motion for rotational motion

θ = ω0 x t + 1/2 α t^2

θ = 2 x 3.14 x 5 x 20 / 60 + 0.5 x 2 x 5 x 5

θ = 10.47 + 25 = 35.47 rad

Number of revolution = 35.47 / (2 x 3.14) = 5.65

a 100mh inductor is placed parallel with a 100 ohm resistor in the circuit , the circuit has a source voltage of 30 vac and a fr

ddd [48]

Answer:

current through the inductor = 0.24 A

Explanation:

given data

inductor = 100mh

resistor = 100 ohm

voltage = 30 vac

frequancy = 200 Hz

to find out

current through the inductor

solution

current through the inductor will be when inductor is place parallel with resistor

across resistor

XL = i2πl

XL = i2π×200×100× $10^{-3}$ = i126.66

current through the inductor = $\frac{voltage}{XL}$

current through the inductor = $\frac{30}{125.66}$

current through the inductor = 0.24 A

Function of a regulator

Karolina [17]

Answer:

the function of the regulator in a power supply:-

A voltage regulator is a component of the power supply unit that ensures a steady constant voltage supply through all operational conditions. It regulates voltage during power fluctuations and variations in loads. It can regulate AC as well as DC voltages.
