The position of a circuit breaker (CB) are .............

1 answer:

6 0

A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit. Its basic function is to interrupt current flow after a fault is detected.

I hope that this answer helps you

A sound wave is moving through air. The wave has a wavelength of 0.65 m and a frequency of 512 Hz. Calculate the speed of the wa

nexus9112 [7]

Answer:

"332.8 m/s" is the right solution.

Explanation:

The given values are:

Wavelength,

$\lambda=0.65 \ m$

Frequency,

$f = 512 \ Hz$

As we know,

⇒ $Speed=Frequency\times Wavelength$

or,

⇒ $V=f\times \lambda$

By putting the given values in the above relation, we get

⇒ $=512\times 0.65$

⇒ $=332.8 \ m/s$

An airplane pilot wishes to fly due west. a wind of 80.0 km> h (about 50 mi > h ) is blowing toward the south. (a) if the

diamong [38]

let the plane is flying at some angle theta with west towards north

Now we can use the components

$v_y = 320 sin\theta$

$v_x = 320 cos\theta$

now since plane has to fly towards west so net speed in north must be equal to speed in south for air

So we can say

$320 sin\theta = 80$

$sin\theta = \frac{1}{4}$

$\theta = 14.5 degree$

so plane has to fly in direction 14.5 degree North of west

Whats the difference between bad conductors , insulators and dielectric

KatRina [158]

Insulators does not allow flow of electric charges at all.
bad conductors are those which can conduct electricity but offers more opposition (resistence) to the flow of current compared to the flow of current in a good conductor.
all dielectrics are insulators, but all insulators are not dielectric.
