Answer:

The answer is A. There is no electric field on the interior of the conducting sphere.

Explanation:

A solid conducting sphere in a uniform electric field will exert force on the charges in the sphere to redistribute themselves in such a way that both the charges and the field inside the sphere would vanish.

A 70.0-kg skier is sliding at 4 m/s when they slide down a 2m high hill. At the bottom of the hill they run into a large 2800 N/
Katarina [22]

Answer:

\Delta x=245\ mm

Explanation:

Given:

  • mass of skier, m=70\ kg
  • initial velocity of skier, u=4\ m.s^{-1}
  • height of the hill, h=2\ m
  • spring constant, k=2800\ N.m^{-1}

<u>final velocity of skier before coming in contact of spring:</u>

Using eq. of motion:

v^2=u^2+gh

v^2=4^2+9.8\times 2

v=5.9666\ m.s^{-1}

<u>Now the time taken by the skier to reach down:</u>

v=u+gt

5.9666=4+9.8\ t

t=0.2007\ s

<u>Now we calculate force using Newton's second law:</u>

F=\frac{dp}{dt}

F=\frac{m(v-u)}{t}

F=\frac{70\times(5.9666-4)}{0.2007}

F\approx686\ N

<u>∴Compression in spring before the skier momentarily comes to rest:</u>

\Delta x=\frac{F}{k}

\Delta x=\frac{686}{2800}

\Delta x=0.245\ m

\Delta x=245\ mm

A puddle of water has a thin film of gasoline floating on it. A beam of light is shining perpendicular on the film. If the wavel
g100num [7]

Answer:

option A

Explanation:

Given,

wavelength of light,\lambda = 560\ nm

refractive index of gasoline, n₁ = 1.40

Refractive index of water, n₂ = 1.33

thickness of the film, t = ?

Condition of constructive interference is given by

2 n t = (m+\dfrac{1}{2})\lambda

For minimum thickness of the film m = 0

From the question we can clearly observe that phase change from gasoline to air

so, n = 1.4

2 \times 1.4 \times t = \dfrac{560}{2}

t = 100\ nm

Hence, the correct answer is option A

What part of the electromagnetic spectrum that is necessary for the sense of sight in humans?
Alekssandra [29.7K]
<span>The part of the electromagnetic spectrum that is necessary for the sense of sight in humans is called visible light. This portion of the electromagnetic spectrum is composed of the various colors that the human eyes can distinguish. Each color has a corresponding wavelength. The human eyes can see wavelengths between 390-700 nm, and visible light ranges from 380-750 nm.</span>
