Answer:

Circuit breaker is an electrical switch placed in a circuit which automatically switches off when there is excess current- overload, short circuit. A circuit breaker automatically breaks the circuit and protects it from damage.

The magnetosphere is the magnetic field of the Earth surrounding it and interacts with the solar wind. Its a region in space where magnetic field of the earth is dominant.

A circuit breaker is an automatic device for stopping the flow of current in an electric circuit as a safety measure.

A magnetosphere is the region surrounding the earth or another astronomical body in which its magnetic field is the predominant effective magnetic field.

Hope this helps!! All credit goes to Google though

What is the charge on an object that has 1.09x10^13 excess electrons?

Nadya [2.5K]

Answer:

$-1.74\cdot 10^{-6} C$

Explanation:

The electron is the particle that rotates around the nucleus of the atom; it has a negative electric charge equal to :

$e=-1.6\cdot 10^{-19}C$

which is known as fundamental charge.

For an object containing N excess electrons, the total charge of the object is

$Q=Ne$

In this problem, the number of excess electrons in the object is:

$N=1.09\cdot 10^{13}$

Therefore, by plugging it the numbers, we can find the value of Q, the total charge of the object:

$Q=(1.09\cdot 10^{13})(-1.6\cdot 10^{-19})=-1.74\cdot 10^{-6} C$

Sever21 [200]

Answer:

$v = 20\pi sec^2\theta$

Explanation:

As we know that the angle made with the vertical is given so we have

$tan\theta = \frac{x}{10}$

so we have

$x = 10 tan\theta$

now differentiate both sides with time

$v = \frac{dx}{dt} = 10 sec^2\theta \frac{d\theta}{dt}$

$v = 10 \omega sec^2\theta$

now we know that

$\omega = 2\pi f$

$\omega = 2\pi (\frac{60}{60})$

$\omega = 2\pi$

now we have

$v = 10(2\pi) sec^2\theta$

$v = 20\pi sec^2\theta$

kenny6666 [7]

Explanation:

As the Sun heats the ocean, the water evaporates, turning into a gas. Sometimes this gas meets cooler air, and the gas changes into drops of water. This process is called condensation. Drops of water fall back down to Earth again as precipitation, which can be in the form of rain, snow, sleet, or hail

three phases of water cycle are

evaporation, condensation, precipitation
