A lot of things but the most important is that they conduct different type of energy

Insulators does not allow flow of electric charges at all.
bad conductors are those which can conduct electricity but offers more opposition (resistence) to the flow of current compared to the flow of current in a good conductor.
all dielectrics are insulators, but all insulators are not dielectric.

hope this help

The floor of the Atlantic Ocean is spreading slowly. It spreads at the rate of 1 to 10 centimeters per year. Why would it be use

Models represent objects, events, and processes in the real world.

Models are often used when an object, event, or process

occurs too slowly or too quickly;

is too small or too large;

is too complicated or too dangerous.

The ocean is spreading at such a slow rate that it would take scientists 50 or more years to collect enough meaningful data from the ocean floor to complete a study. Therefore, scientists use models in order to both predict how the floor will keep spreading and to understand what the ocean floor looked like thousands of years in the past.

Answer:

Fringe width = 21 mm

Explanation:

Fringe width is given by the formula

$\beta = \frac{\Lambda L}{d}$

here we know that

$\Lambda = 564 nm$

L = 4.0 m

d = 0.108 mm

now from above formula we will have

$\beta = \frac{(564 \times 10^{-9})(4.0 m)}{0.108\times 10^{-3}}$

$\beta = 0.021 meter$

so fringe width on the wall will be 21 mm

The field inside a charged parallel-plate capacitor is __________.

Bess [88]

<span>Uniform. A parallel plate capacitor is a simple arrangement of electrodes and dielectric to form a capacitor. Here two parallel conductive plates are used as electrodes with a medium or dielectric in between them. Charge separation in a parallel-plate capacitor causes an internal electric field, which is uniform.</span>

Aneli [31]

Answer:

The moment of inertia of the turntable about the rotation axis is 0.0225 kg.m²

Explanation:

Given;

radius of the turnable, r = 60 cm = 0.6 m

rotational kinetic energy, E = 0.25 J

angular speed of the turnable, ω = 45 rpm

The rotational kinetic energy is given as;

$E_{rot} = \frac{1}{2} I \omega ^2$

where;

I is the moment of inertia about the axis of rotation

ω is the angular speed in rad/s

$\omega = 45 \frac{rev}{\min} \times \frac{2 \pi \ rad}{1 \ rev} \times \frac{1 \ \min}{60 \ s} \\\\\omega = 4.712 \ rad/s$

$E = \frac{1}{2} I \omega ^2\\\\I = \frac{2E}{\omega ^2} \\\\I = \frac{2 \ \times \ 0.25}{(4.712)^2} \\\\I = 0.0225 \ kg.m^2$

Therefore, the moment of inertia of the turntable about the rotation axis is 0.0225 kg.m²
