A small charged ball lies within the hollow of a metallic spherical shell of radius R. For three situations, the net charges on

the ball and shell, respectively, are (1) +4q, 0; (2) –6q, +10q; (3) +16q, –12q. Rank the situations according to their charge on (a) the inner surface of the shell and (b) the outer surface, most positive first

Answer: a) 2) > 1) > 3) b) 1) = 2) = 3) Explanation: Through charge induction, the magnitude of the charge on the inner surface of the outer shell matches that of the small sphere inside, but with the opposite sign. Therefore, we can conclude: 1) + 4q, so the inner surface has a charge of -4q and the outer surface is +4q; 2) -6q, +10q, giving the inner surface a charge of +6q and the outer surface +4q; 3) +16q, -12q, thus the inner surface charge is -16q and the outer surface is +4q.

Blue light, which has a wavelength of about 475 nm, is made to pass through a slit of a diffraction grating that has 425 lines p
Yuliya22 [3333]
The equation that connects the various variables is:

distance between lines * sin(angle of diffraction) = order of band * wavelength

dsin(∅) = nλ

To calculate the spacing between the lines, we can use the information that there are 425 lines per mm, and since 1 mm is equivalent to 0.001 m, we find

d = 0.001 / 425 = 2.35 x 10⁻⁶ m
The wavelength is λ = 475 x 10⁻⁹ m

By substituting these values,

2.35 x 10⁻⁶ * sin(∅) = 1 * 475 x 10⁻⁹
∅ = 11.7°


Thus, the angle for the first-order bright band, or maxima, is 11.7°

Two racecars are driving at constant speeds around a circular track. Both cars are the same distance away from the center of the
Yuliya22 [3333]

Response:

The acceleration of car 2 is four times that of car 1.

Rationale:

Centripetal acceleration occurs when an object travels in a circular route. It can be expressed as:

a=\dfrac{v^2}{r}

In this scenario, two race cars are moving at consistent speeds around a circular course. Both automobiles are located at an equal distance from the center, but car 2 is operating at twice the speed of car 1.

Thus,

\dfrac{a_1}{a_2}=\dfrac{v_1^2}{v_2^2}

1 and 2 represent the first and second cars, respectively.

v_2=2v_1

Consequently,

\dfrac{a_1}{a_2}=\dfrac{v_1^2}{(2v_1)^2}\\\\\dfrac{a_1}{a_2}=\dfrac{v_1^2}{4v_1^2}\\\\\dfrac{a_1}{a_2}=\dfrac{1}{4}\\\\a_2=4\times a_1

Therefore, car 2's acceleration is four times that of car 1.
