What is a generator and how does it create energy?

Answer:

<em>Hello! Todobaku here!!</em>

Explanation:

An electricity generator is a device that converts a form of energy into electricity. Generators operate because of the relationship between magnetism and electricity. Generators that convert kinetic (mechanical) energy into electrical energy produce nearly all of the electricity that consumers use.

A solid conducting sphere with radius R = 0.390 m carries a net charge of +0.650 nC.

Tom [10]

Answer:

38.5 N/C

Explanation:

The electric field generated by a charged sphere at a point outside the sphere is equivalent to the electric field generated by a single point charge, and it is given by

$E=k\frac{Q}{r^2}$

where

$k=9\cdot 10^9 Nm^2C^{-2}$ is the Coulomb's constant

Q is the net charge

r is the distance from the centre of the sphere

In this problem, we have

$Q=+0.650 nC=0.65\cdot 10^{-9}C$

$r=0.390 m$

Substituting into the equation, we find

$E=(9\cdot 10^9)\frac{(0.65\cdot 10^{-9}C)}{(0.390m)^2}=38.5 N/C$

A test charge of +3 µC is at a point P where the electric field due to the other charges is directed to the right and has a magn

umka2103 [35]

Answer:

Electric field will remain same.

Explanation:

Given that

At initial condition ,charge q = +3μ C

Electric field E = 4106 N/c

As we know that

Electric field due to charge q

$E=\dfrac{kq}{r^2}$

Now when charge is replaced by new charge q'= -3μ C

From the expression of electric field we can say that electric field will remain same from same quantity of electric charge.

So we can say that electric field will remain same.

What is the speed of light in water?

Fudgin [204]

Answer:

Speed of the light in water= 225,000 km/s

Explanation:

At the speed with which light propagates through a homogeneous and transparent medium, it is a constant characteristic of that medium, and therefore, it changes from one medium to another.

Due to its enormous magnitude, the measurement of the speed of light has required the invention of ingenious procedures that will overcome the inconvenience of short land distances in relation to such extraordinary speed.

Astronomical methods and terrestrial methods have been giving ever closer results. At present, the value c = 299,792,458 km / s is accepted for the speed of light in a vacuum. In any transparent material medium the light propagates with a speed that is always lower than c. Thus, for example, in water it does so at around 75% of the speed of light in a vacuum: about 225,000 km / s.
