Answer:

Snell's Law:    N1 sin θ1 = N2 sin θ2

n1 sine1 = n2 sin 82 fits this description

The formula that represents Snell's law is n₁sinθ₁ = n₂sinθ₂. Thus, the correct solution is option B.

When light rays from one medium enter into another medium (rarer to denser medium), the speed of light rays is decreased when light rays enter from rarer to denser medium. This is called as refraction of light rays.

The laws of refraction give Snell's law. The ratio of the sine of the angle of incidence and the ratio of the sine of the angle of refraction is equal to constant (μ) is called Snell's law.

The Snells law, sin i / sin r = μ, where i is the angle of incidence and r is the angle of refraction. μ is the refractive index of the medium. The refractive index remains constant for the medium.

From the given,

Snell's law is written as, sin i / sin r = n₁/n₂, where n₁ and n₂ is the refractive index of the medium. Thus, n₁sin(i) = n₂sin(r).

Thus, the ideal solution is option B.

The frictional forces acting on the box at this time will be 2.88 N.

It is a type of opposition force acting on the surface of the body that tries to oppose the motion of the body. its unit is Newton (N).

Mathematically, it is defined as the product of the coefficient of friction and normal reaction.

The reaction force on the box is;

R=mg

R=F

R=12 N

Answer:

When an electron is hit by a photon of light, it absorbs the quanta of energy the photon was carrying and moves to a higher energy state. One way of thinking about this higher energy state is to imagine that the electron is now moving faster, (it has just been "hit" by a rapidly moving photon)

A photon is a quantum of EM radiation. Its energy is given by E = hf and is related to the frequency f and wavelength λ of the radiation by. E=hf=hcλ(energy of a photon) E = h f = h c λ (energy of a photon) , where E is the energy of a single photon and c is the speed of light.

Answer:

Explanation:

yes object can move through a distance  and can have zero displacement  

as displacement is the shortest distance between two points eg: if a person has moved a distance of 20 m and comes back to his original place by moving back 20m in such a case  distance moved by the person is 40m but his displacement is 0 as shortest distance covered by him is 0 as he is in his original place

Yes, it is possible for a body to have traveled a distance yet have a displacement of zero.

Distance traveled by a body is the length of the path covered by it.

On the other hand displacement of a body is the shortest distance between the initial and the final point of a body.

When a body is traveling such that it ends at the point from where it started its journey, it covers a distance but the displacement of the body is zero.

So a body that has moved through a distance can have zero displacement.

If the angle between their initial directions was 90 ∘ , their speed after the collision will be 4.35 m/s.

When two moving bodies after colliding stick to each other and move together is called the inelastic collision.

In inelastic collision , momentum is remains conserved.

Initial momentum =Final momentum

m₁u₁ +m₂u₂ = (m₁ +m₂ )v

where, u₁ and u₂ represents initial velocities of two hockey players and v₁ and v₂ shows the final velocities.

m₁ =m₂ =m and u₁ = u₂ =u

Substitute the values from the question, we get

2mu = 2mv

u =v

u = v x cos (θ/2)

u = 6.15 cos(90/2)

u = v = 4.35 m/s

Thus, the speed after collision is 4.35 m/s.

The tension in the cables are :  a) 984 N when moving up,

b) 584 N when movng down

Given data:

mass = 80 kg

Acceleration = 2.5 m/s

A) When moving up

Tension in the cable = m*g + m*a

                                  = 80 * 9.8 + 80 * 2.5

                                  =  984 N

B) When moving down

Tension in the cable = m*g - m*a

                                  = 80 * 9.8 - 80 * 2.5

                                  = 584 N

Hence we can conclude that the tension in the cable are 984 N moving up and 584 moving down.

Hi there!

Using Faraday's and Lenz's Law:
[tex]\epsilon = -N\frac{d\Phi_B}{dt}[/tex]

ε = Induced emf (V)

N = number of loops/turns
Φ = Magnetic flux (Wb)

Magnetic flux is given as:
[tex]\Phi_B = \oint B \cdot dA = B\cdot A[/tex]
Since the area of the loops remains constant, we can take area out of the time derivative. Thus:
[tex]\frac{d\Phi_B}{dt} = A * \frac{dB}{dt} = A * \frac{\Delta B}{\Delta t}[/tex]

Also, since the magnetic field is applied at a right angle to the plane of the coil, that means that the field is PARALLEL to the area vector of the plane of the coil. (points normal to the surface). This means we can disregard the dot product since cos(180) = 1.

Plug in the given values.

[tex]\epsilon = - 50 * 3.6 * \frac{0.88 - 0}{1.85} = -85.622 V[/tex]

The negative sign simply means that the induced emf is in the opposite direction in order to oppose the increase in magnetic flux, so the magnitude is simply:

[tex]\epsilon = \boxed{85.622 V}[/tex]

For the current, we can use Ohm's Law:
[tex]i = \frac{\epsilon}{R}\\\\i = \frac{85.622}{5} = \boxed{17.124 A}[/tex]

As the ray of light moves parallel to the base line of the prism inside it, so angle of refraction = r = 30° (equilateral prism)

Now, we know that:

[tex]{:\implies \quad \sf \sin (i)=\mu \sin (r)}[/tex]

[tex]{:\implies \quad \sf \sin (i)=\sqrt{3}\sin (30^{\degree})}[/tex]

[tex]{:\implies \quad \sf \sin (i)=\dfrac{\sqrt{3}}{2}}[/tex]

[tex]{:\implies \quad \sf \sin (i)=\sin (60^{\degree})}[/tex]

Therefore, angle of incidence is 60°

Given ,

[tex]r = \sqrt{3}[/tex]

Now ,

[tex] \longrightarrow \sin(i) = \sqrt{3} \: \sin(30°)[/tex]

[tex] \: \: \: \: \: \: \: \: \: \: \: \: [/tex]

[tex]\longrightarrow \sin(i)= \sqrt{ \frac{3}{2} }[/tex]

[tex] \: \: \: \: \: \: \: \: \: \: \: \: [/tex]

[tex] \longrightarrow \: i = 60°[/tex]

The angle of incidence is 60°.
