Answer:

The gravity model predicts that the optimal location of a service is directly related to the population of people in a given location and inversely related to the distance people must cover in search of it.

An optimal service is directly dependent on the size of people in that given area . The larger the people the larger the customers and vice versa.

If the place is far then less people will patronize because people won’t be willing to go through such stress to get such goods or services.

Assuming the diode is ideal but with a forward voltage drop of. 65 volts, what is the current in ma if v1=0v, and r1=490ω?

weeeeeb [17]

The current in the ideal diode with forward biased voltage drop of 65V is 132.6 mA.

To find the answer, we have to know more about the ideal diode.

<h3>What is an ideal diode?</h3>

A type of electronic component known as an ideal diode has two terminals, only permits the flow of current in one direction, and has less zero resistance in one direction and infinite resistance in another.
A semiconductor diode is the kind of diode that is used the most commonly.
It is a PN junction-containing crystalline semiconductor component that is wired to two electrical terminals.

<h3>How to find the current in ideal diode?</h3>

Here we have given with the values,

$V_2=65V\\V_1=0V\\R_1=490Ohm.$

We have the expression for current in mA of the ideal diode with forward biased voltage drop as,

$I=\frac{V_2-V_1}{R_1} =\frac{65}{490} =132.6mA$

Thus, we can conclude that, the current in mA of the ideal diode with forward biased voltage drop of 65 V is 132.6.

Olenka [21]

I don't know where you live, but chances are you won't see much at all. Light pollution levels have increased so much due to street lamps and other lights that it's practically impossible to see stars in the night time with the naked eye.

A crystal is irradiated with x-rays with a wavelength of 0.120 nm. the atomic planes in the crystal are separated by 0.21 nm. at

Kryger [21]

The angles of incidence with respect to the normal will the x-rays reflect from the crystal will be 16.60 degrees.

Given: wavelength of X-rays, λ= 0.120 nm

Distance, d=0.21 nm

According to Bragg’s diffraction law: nλ = 2dsinθ

thus, 0.120 = 2*0.21sinθ

or θ = $sin^{-1}$ (0.120/2*0.21)

or θ = 16.60 degrees.

A moving company is called into a building and asked to relocate 520 bricks to a location 15 meters above the ground. If each br

slamgirl [31]

The total weight of the load is (mass) x (gravity) x (height) .

Weight = (520 x 4kg) x (9.8 m/s²)

Weight = (2,080 kg) x (9.8 m/s²)

Weight = 20,384 newtons

Work = (force) x (distance)

Work = (20,834 N) x (15 m)

Work = 305,760 Joules

A hiker travels 12 km in a direction of 50 degrees west of north. What are the north and west components of this displacement?

olya-2409 [2.1K]

The north and west components of this displacement are 9.19 km and -7.71 km respectively.

<h3>North component of the displacement</h3>

The north component of the displacement is calculated as follows;

Dy = D sinθ

Dy = 12 km x sin50

Dy = 9.19 km

<h3>West component of the displacement</h3>

Dx = D x cosθ

Dx = - 12 km x cos(50)

Dx = -7.71 km
