The diagrams show objects’ gravitational pull toward each other. 3 diagrams labeled X, Y, and Z. X: 2 circles approximatley 2 in

ches apart, arrows from each circle pointing to the opposite circle. Y: 2 larger circles the same distance apart as in X, with thicker arrows from each circle pointing to the opposite circle. Z: 2 circles the same size as in X, but much farther apart, thinner arrows from each circle pointing to the opposite circle. Which statement describes the relationship between diagram X and Y? Gravity attracts only larger objects toward one another. Gravity attracts larger objects only if they are close to one another. If the masses of the objects increase, then the force between them also increases. If distance between the objects increases, then the amount of force also increases.

A 21.3 A current flows in a long, straight wire. Find the strength of the resulting magnetic field at a distance of 45.7 cm from
Bezzdna [24]

Answer:

The magnetic field strength due to current flowing in the wire is9.322 x 10⁻⁶ T.

Explanation:

Given;

electric current, I = 21.3 A

distance of the magnetic field from the wire, R = 45.7 cm = 0.457 m

The strength of the resulting magnetic field at the given distance is calculated as;

B = \frac{\mu_o I}{2\pi R}

Where;

μ₀ is permeability of free space = 4π x 10⁻⁷ T.m/A

B = \frac{\mu_o I}{2\pi R}\\\\B = \frac{4\pi*10^{-7} *21.3}{2\pi(0.457)}\\\\B = 9.322 *10^{-6} \ T

Therefore, the magnetic field strength due to current flowing in the wire is 9.322 x 10⁻⁶ T.

Do the math for 30%÷75
Dafna1 [17]

" 30% " means " 0.30 "

30% ÷ 75  means  (0.30 / 75) = <em>0.004</em>

Your aunt just turned 50 and now needs glasses to read.
alexira [117]

Answer:

(a) hypermetropia

(b) convex lens

(c) 133.33 cm

(d) - 21.05 cm

Explanation:

(a) As she is old age, so she is suffering from hypermetropia.

(b) It is the defect due to which a person is not able to see the nearby objects clearly, so it is cured by convex lens of suitable focal length.

(c) Power, P = + 0.75 D

Focal length is the reciprocal of power of lens.

f = 1/ P = 1/0.75

f = 133.33 cm

(d) v = -25 cm, f = 133.3 cm

use lens equation

\frac{1}{f}=\frac{1}{v}-\frac{1}{u}

\frac{1}{133.3}=\frac{-1}{25}-\frac{1}{u}

\frac{-1}{u}=\frac{133.33+25}{133.33\times25}

u = - 21.05 cm

Does a emp effect electronics it hits forever and does it fry it
Free_Kalibri [48]
I recently received the following question regarding EMP effects: “What will happen to vehicles with electronic ignitions, a Chevy with an ignition module, but they are not hooked to a battery, with no path for electricity to follow, can it do damage? There may not be power on the grid, but what about a generator? Can a drill that was not plugged in still be able to run?”

The short answer is, maybe.
