A 40.0-μFcapacitor is connected across a 60.0 Hz generator. An inductor is then connected in parallel with the capacitor. What i

amm1812

Answer:

The value of the inductance is 175.9 mH.

Explanation:

Given that,

Capacitor $C= 40.0\ \muF$

Frequency = 60.0 Hz

The inductor and capacitor is connected in parallel, the voltage across each of these elements is the same.

We have,

$V_{L}=V_{C}$

Using ohm's law

$I_{rms}\times X_{L}=I_{rms}\times X_{C}$

$X_{L}=X_{C}$

$2\pi f L=\dfrac{1}{2\pi f C}$

$L=\dfrac{1}{4\pi^2\times f^2\times C}$

Put the value into the formula

$L=\dfrac{1}{4\times\pi^2\times60.0^2\times40\times10^{-6}}$

$L=0.1759\ H$

$L=175.9\times10^{-3}\ H$

$L=175.9\ mH$

Hence, The value of the inductance is 175.9 mH.

A ship can carry more load than aeroplane of same size. why?

stepladder [879]

Answer:

density of water is much greater than density of air

Explanation:

when body is in fluid it carries weight which is always equal to upthrust

upthrust is given as

upthrust= density of fluid ×strength of gravitational field g × volume of body in fluid

as volume of ship and aeroplane is same and strength of gravitational field or acceleration due to gravity is same hence upthrust depens upon density of fluid .

density of air is about 1.2 kg/m^3 and density of water is 1000kg/m^3 hence ship carries more load

5. A store clerk moved a 4.4-kg box of soap without acceleration along a shelf by pushing it with a horizontal force of magnitud

lesantik [10]

The box moved 0.73 m

<u>Explanation:</u>

Given data,

Magnitude 8.1 N Work on the box 5.9 J Clerk move a 4.4 Kg

Distance= work done on the box / Horizontal force on the magnitude

= 5.9/8.1

=0.728

Distance =0.73 m

The box moved 0.73 m

Two train 75 km apart approach each other on parallel tracks, each moving at

creativ13 [48]

Answer:

The correct solution is "37.5 km".

Explanation:

Given:

Distance between the trains,

d = 75 km

Speed of each train,

= 15 km/h

The relative speed will be:

= $15 + (-15)$

= $30 \ km/h$

The speed of the bird,

V = 15 km/h

Now,

The time taken to meet will be:

$t=\frac{Distance}{Relative \ speed}$

$=\frac{75}{30}$

$=2.5 \ h$

hence,

The distance travelled by the bird in 2.5 h will be:

⇒ $D = V t$

$=15\times 2.5$

$=37.5 \ km$

If you are driving an oscillatory system at a certain frequency, but the amplitude is much smaller than it could be, you can be

kakasveta [241]

Answer:

3. The driving frequency is not matched to the natural frequency of the oscillatory system.

Explanation:

It is the condition of resonance when the one body that oscillates with a maximum amplitude when the frequency of the applied force is equal to the natural frequency of the body.

Every body has its own natural frequency.

Here the driving force may be more or less but we are sure that it is not equal to the natural frequency of oscillatory system. Hence the force is not in resonance with the oscillatory system.
