Answer:

Explanation:

Given that a jogger runs 186 meters westward, then 210 meters eastward, then 156 meters westward, and finally 8A meters eastward.

To calculate the displacement, let assume that the

Westward = positive

Eastward = negative

Displacement = 186 - 210 + 156 - 84

Displacement = 342 - 294

Displacement = 48 m

Since the answer is positive, the direction of the displacement will be westward.

Tomtit [17]

Answer:

C. Both A and B

Explanation:

Fuses are rated by the amperage they can carry before heat melts the element. The fuse is ideal for protection against short circuits. Short circuits produce enough amperage to vaporize a fuse element and break connection in one cycle of a 60-cycle system.

Specifically, the voltage rating determines the ability of the fuse to suppress the internal arcing that occurs after a fuse link melts and an arc is produced.

) each plate of a parallel-plate air-filled capacitor has an area of 0.0020 , and the separation of the plates is an electric fi

Dvinal [7]

I attached the full question.
We know that for a parallel-plate capacitor the surface charge density is given by the following formula:
$\sigma=\varepsilon_0 \frac{V}{d}$
Where V is the voltage between the plates and d is separation.
Voltage is by definition:
$V=Ed$
Voltage is analog to the mechanical work done by the force.
Above formula is correct only If the field is constant, and we can assume that it is since no function has been given.
The charge density would then be:
$\sigma=\varepsilon_0 \frac{Ed}{d}=\varepsilon_0E\\
\sigma= 8.85\cdot10^{-12}\cdot 2.1\cdot 10^6= 0.0000185\frac{c}{m^2}$
Please note that elecric permittivity of air is very close to elecric permittivity of vacum, it is common to use them <span>interchangeably</span>.

5. is the earth’s magnetic field parallel to the ground at all locations? if not, where is it parallel to the surface? is its st

Setler79 [48]

The Earth's magnetic field lines appear to emanate perpendicularly from the poles and go round along the Earth from the South Pole to the North Pole. Therefore, the Earth's magnetic field is generally not parallel to the ground at every location. It is parallel to the earth at the equator near the earth's surface.

The Earth's magnetic field, also known as the geomagnetic field, is a magnetic field that extends from the Earth's interior into space, where it interacts with the solar wind, a stream of charged particles emanating from the Sun.

The magnetic field varies in strength over the earth's surface. It is strongest at the poles and weakest at the equator.

To know more about Earth's magnetic field,
