As we know, period (t)of a wave and it's frequency (f) are Reciprocal of each other, so if one is know then we can just reverse the order to get the other one.

that is :

[tex]\qquad \sf  \dashrightarrow \: frequency = \dfrac{1}{period} [/tex]

Now, let's move on to problems ~

# 11. f = 15 hertz, t = ?

[tex]\qquad \sf  \dashrightarrow \: t = \dfrac{1}{15} \: \: sec[/tex]

[tex]\qquad \sf  \dashrightarrow \: t \approx0.067 \: \: sec[/tex]

#12. f = 292 hertz, t = ?

[tex]\qquad \sf  \dashrightarrow \: t = \dfrac{1}{292} \: \: sec[/tex]

[tex]\qquad \sf  \dashrightarrow \: t \approx0.0034 \: \: sec[/tex]

#13. t = 12 seconds, f = ?

[tex]\qquad \sf  \dashrightarrow \: f= \dfrac{1}{12} \: \: hertz[/tex]

[tex]\qquad \sf  \dashrightarrow \: f \approx0.083 \: \: hertz[/tex]

We know that, frequency = reciprocal of the period of time an object swings or vibrates at. Therefore,

Displacement(s)=3.8m

As we have,

Work=Force×displacement

Now,

[tex]\hookrightarrow 1780J=F\times3.8m\\\\\hookrightarrow \frac{1780J}{3.8m} =F\\\\\hookrightarrow F=468.42N[/tex]

Due to concentration difference, electric charge flows from a region of high electric potential to a region of low electric potential.

Electric charge flows from a region of high electric potential to a region of low electric potential because of concentration difference. This movement is same as the diffusion in which molecules move from high concentration to lower concentration.

So we can conclude that due to concentration difference, electric charge flows from a region of high electric potential to a region of low electric potential.

Final speed of the tennis ball, moving with a speed of 5. 82 m/s , has a head-on collision with a 0. 090-kg ball is 2.964 m/s.

Momentum of an object is the force of speed of it in motion. Momentum of a moving body is the product of mass times velocity. By the law of conservation of momentum,

[tex]m_1u_1 + m_2u_2 = (m_1+m_2)v[/tex]

Here, (m) is the mass, (u) is initial velocity before collision, v is final velocity after collision and (subscript 1, and 2) are used for body 1 and 2 respectively. Rewrite the formula for final velocity as,

[tex]v=\dfrac{m_1u_1 + m_2u_2}{(m_1+m_2)}[/tex]

A 0. 060-kg tennis ball, moving with a speed of 5. 82 m/s, has a head-on collision with a 0. 090-kg ball, initially moving in the same direction at a speed of 3.44 m/s. Thus, the initial velocity of the second ball is,

Compared to the electric field energy density at b, the electric field energy density at a is large by a factor of 16.

The energy of a particle by virtue of its position.

The potential at B = Vb =V

Vb = 1/4π∈₀ x e/r₁ = ke/r₁

V =ke/r₁

and r₁ = ke /V

The potential at A = Va = 2V

2V = ke/r₂

r₂ = ke/2V

The electric field at point B. Eb = ke/r₁²

Substitute the value of r₁, we get

Eb = V²/ke

The electric field at point A , Ea = ke /r₂²

Substitute the value of r₂, we get

Ea = 4V²/ke

The electric field energy density at point A and B,

Ua  = 1/2 ∈Ea²

Ub = 1/2 ∈Eb²

electric field energy density is proportional to the square of electric field at the particular point.

Ua/Ub =(Ea/Eb)²

Explanation:

dark fringe equation = dsinθ = (m + 1/2)λ

sinθ = [(m + 1/2)λ]d

sinθ1 = [(m + 1/2)λ]d

sinθ1/sinθ =  [(m + 1/2)(λ/d)] / [[(m + 1/2)(λ/d)] = [(m + 1/2)] / [(m + 1/2)]

sinθ1 = [(m + 1/2)] / [(m + 1/2)] (sinθ)

sinθ1 = [1+1/2]/[0+1/2] (sin15)

sinθ1 = 3sin15

sinθ1 = 0.77645

θ1 = sin^-1( 0.77645)

θ1 = 50.94° = 51°

The dark fringe for m = 0 in a young's double-slit experiment is located at an angle. The angle that locates the dark fringe for m = 1 is  51°.

When light passes through a slit , it produces a spectrum which can be seen on the screen kept a distance in form of fringes of different intensity. The fringe with intensity zero is called the dark fringe.

Given is the angle θ = 15°

The equation for the dark fringe is

d sinθ = (m + 1/2)λ

For m= 0 and m=1, the ratio of the sines  is

sinθ₁/sinθ₀ = [(m + 1/2)] / [(m + 1/2)]

Rearranging for sinθ₁, we have

sinθ₁ = [(m + 1/2)] / [(m + 1/2)] (sinθ₀)

Substituting the values into the equation and solving for θ₁

sinθ₁ = [1+1/2]/[0+1/2] (sin15)

θ₁ = 51°

Thus, the angle that locates the dark fringe fro m = 1 is 51°.
