A total electric charge of 3.50 nC is distributed uniformly over the surface of a metal sphere with a radius of 24.0 cm. If the

djyliett [7]

Answer:

a, V = 65.6V

b. V = 131.0V

C. V = 131.0V

Explanation:

Given

Total electric charge $q= 3.50nC=3.50\times10^{-9}C$ distributed uniform at surface of metal sphere where radius is R = 24cm

R = 24cm = 0.024m

we have to find potential at different distance

a. r = 48cm = 0.048m

b. r = 24cm = 0.024m

c. r = 12cm = 0.012m

a. solution

Here the distance r is grater then R,we can get the potential outside of sphere

$V = \dfrac{q}{4\pi\varepsilon_0r}$

$\textrm{where is} \dfrac{1}{4\pi\varepsilon_0}=9.0\times10^{9}N.m^{2}/c^2$

now we plug the value q and r in potential v

$V=(9\times10^9N.m^2/C^2)\dfrac{3.50\times10^{-9}C}{0.48m}$

=65.6V

b.solution

Here distane r is the same from radius R, so we can get potential inside sphere

$v= \dfrac{q}{4\pi\varepsilon_0R}$

Now we plug the value of R and q

$V=(9\times10^9N.m^2/C^2)\dfrac{3.50\times10^{-9}C}{0.24m}$

$V=131V$

3.solution

Inside sphere electric feild is zero.so potential is the same every point inside sphere and equal potential on the surface

$V=131V$

Small birds can migrate over long distances without feeding, storing energy mostly as fat rather than carbohydrate. (Figure 1) F

Katen [24]

Answer: 3.1107grams of fat.

Explanation:The speed to cover 800 km in 20 hours will be 40km/hr, Because

Speed =Distance/Time.

This is equal to 72,000 seconds. At a power consumption of 1.7 W, the bird will consume (1.7 X 72,000) =122,400 J of energy.

A gram of fat contains about (9.4 Calories X 4186 J/Calorie) ,=39348 joules of energy, the bird will need (122,400 / 39,348) = 3.1107 grams of fat.

How a body is charged ?

katen-ka-za [31]

Answer:

Explanation:

Following are the three important ways by which a body can get charged. ⇒ By conduction :When an uncharged body is made in contact with a charged body, the charge flow into the non charged body and the body gets charged. ⇒ By rubbing: When a body is rubbed with another body, both of them gets charged.

Moving water, like that of a river, carries sediment as it moves along its bed. The faster the water flows, the more sediment th

nikdorinn [45]

Well newton's law is esstenaily how gravity works. so the force in this case water moves, the more the object (sediment) will go farther. And when the force is lessened the object will eventually come to a dead stop.
