Answer:

The benefits are defined throughout the section described according to the particular context.

Explanation:

Just before it completes its function, users should substitute a fuse, although circuit breakers work through a trigger where you essentially restart or reboot.
Fuses become composed of such a lump of material (metal) that can explode when enough electric current is passed through everything, disturbing another circuit successfully therefore stopping the equipment from hitting another power outage.

Answer:

Explanation:

Circuit breaker is an automatic electrical switch which cuts the power when there is surge in current.

Advantages of Circuit breaker

They are more reliable i.e. they are not replaced frequently
Efficient and easy to safeguard electrical appliance

Disadvantage of Circuit breaker

They are less sensitive than fuses i.e. fuses are much faster than circuit breaker.

A plane is traveling with an air velocity of 720 kilometers/hour due east. It experiences a headwind of 16 kilometers/hour. Find

balandron [24]

If it is a headwind it means it's travelling against the motion of the plane. This means it's velocity is simply v=720-16=704 km/h due east.

At what displacement of a sho is the energy half kinetic and half potential? what fraction of the total energy of a sho is kinet

As we know that KE and PE is same at a given position

so we will have as a function of position given as

$KE = \frac{1}{2}m\omega^2(A^2 - x^2)$

also the PE is given as function of position as

$PE = \frac{1}{2}m\omega^2x^2$

now it is given that

KE = PE

now we will have

$\frac{1}{2}m\omega^2(A^2 - x^2) = \frac{1}{2}m\omega^2x^2$

$A^2 - x^2 = x^2$

$2x^2 = A^2$

$x = \frac{A}{\sqrt2}$

so the position is 0.707 times of amplitude when KE and PE will be same

Part b)

KE of SHO at x = A/3

we can use the formula

$KE = \frac{1}{2}m\omega^2(A^2 - x^2)$

now to find the fraction of kinetic energy

$f = \frac{KE}{TE} = \frac{A^2 - x^2}{A^2}$

$f = \frac{A^2 - (\frac{A}{3})^2}{A^2}$

$f_k = \frac{8}{9}$

now since total energy is sum of KE and PE

so fraction of PE at the same position will be

$f_{PE} = 1 - f_k$

$f_{PE} = 1 - (8/9) = 1/9$
