Answer:

∈= $3.1584x10^{26} \frac{V}{m}$

Explanation:

Using the Gauss Law to determine the electric field of the net flux at the surface of the nucleus

∈ $=\frac{P}{E_{o}}$

The P is the charge density and 'Eo' is the constant of permittivity in free space

to find P

$P=\frac{q}{V}$

$V=\frac{4}{3}*\pi*r^3$

$V=\frac{4}{3}\pi*(7x10^{-15})^3$

$V=2.932x10^{-14} m^3$

$P=\frac{82C}{2.932x10^{-14}m^3}=2.7965x10^{15} \frac{C}{m^3}$

So replacing

∈ $=\frac{2.7965x10^{15}\frac{C}{m^3}}{8.8542x10^{-12}\frac{C^2}{N*m^2}}$

∈= $3.1584x10^{26} \frac{V}{m}$

D. a and c

Explanation:

To make a generator out of a bicycle, Devon will need two magnets and coil of wire.

There is a close knit relationship between magnetism and electricity. Electricity can be generated by a wire changing flux in the presence of a magnetic field.

The magnets provide magnetic field for the process.
The coil of wire is placed in between the magnetic field generated by the magnets.
The bicycle pedal is connected to the set up to turn the wire in between the magnetic fields.
This way, electricity is produced.

What is the amount of work done when JoAnne throws a baseball 2 meters at a force of 40

sergiy2304 [10]

Answer:

Amount of work done by Joanne = 80 joule

Explanation:

Given:

Displacement of ball = 2 meters

Force applied = 40 newtons

Find:

Amount of work done by Joanne

Computation;

Work done = Force applied x Displacement

Amount of work done by Joanne = Force applied x Displacement of ball

Amount of work done by Joanne = 40 x 2

Amount of work done by Joanne = 80 joule
