Answer:

20.8 ft³

Explanation:

The following data were obtained from the question:

Initial pressure (P1) = 80 psi

Initial volume (V1) = 13 ft³

Final pressure (P2) = 50 psi

Final volume (V2) =?

The new volume of the gas can be obtained by using the Boyle's law equation as shown below:

P1V1 = P2V2

80 × 13 = 50 × V2

1040 = 50 × V2

Divide both side by 50

V2 = 1040 / 50

V2 = 20.8 ft³

Thus, the volume of the gas at a pressure of 50 psi is 20.8 ft³

Answer: Calendar

Explanation: I'm pretty sure it is calendar.

Answer:

2 m/s

Explanation:

The total time = 1 hour

The vertical displacement = 1 - 1

Vertical displacement = 0

Horizontal displacement = 4 - 2

Horizontal displacement = 2

Total displacement = sqrt (2^2 - 0^2)

Displacement - 2

Average velocity is displacement/time

= 2x1

=  2 m/s

The average velocity is 2 metres per second.

Answer:

W = 3934 N ,     m = 401.43 kg

Explanation:

This problem can be solved using the rotational equilibrium relation, where we place the reference system at the pivot point and assume that the counterclockwise turns are positive.

     ∑τ = 0

     F 7 - W 1 = 0

    W = F 7/1

     W = 562 7

     W = 3934 N

W = mg

     m = W / g

     m = 3934 / 9.8

     m = 401.43 kg

Answer:

Explanation:

the formula for calculating the linear velocity is expressed as;

v = wr

w is the angular velocity

r is the radius

r = d/2 = 18/2

r = 9 m

Given that 1rev/min = 0.10472rad/s

4.9 rev/min = x

x = 4.9 * 0.10472

x = 0.513128 rad/s

Substitute into the given formula;

v = 9 * 0.513128

V = 4.61m/s

Hence the velocity of the child in m/s is 4.6m/s

Answer:

a

 [tex]y_1 = 0.004589 \ m[/tex]

b

 [tex]y_2 =0.009179 \ m[/tex]

Explanation:

From the question we are told that

   The wavelength of the red light is  [tex]\lambda _r = 633 \ nm = 633 *10^{-9} \ m[/tex]

    The width of the slit is  [tex]d = 0.40 mm = 0.40 *10^{-3} \ m[/tex]

    The distance of the screen from the point of diffraction is [tex]D = 2.9 \ m[/tex]

Generally the width of the central bright fringe is mathematically represented as

       [tex]y_1 = \frac{\lambda * D}{d}[/tex]

=>    [tex]y_1 = \frac{633 *10^{-9} * 2.90 }{0.40 *10^{-3}}[/tex]

=>    [tex]y_1 = 0.004589 \ m[/tex]

Generally the width of the first bright fringe on either side of the central one is mathematically represented as

     [tex]y_2 = 2 * y_1[/tex]

=>   [tex]y_2 = 2 * 0.004589[/tex]

=>   [tex]y_2 =0.009179 \ m[/tex]

• initial vertical speed: 0

Explanation:

We need to find the index of refraction of a material for which the wavelength of light is 0.671 times its value in a vacuum.

The wavelength in any medium is given by :

[tex]\lambda_m=\dfrac{\lambda}{n}[/tex]

Where, [tex]\lambda[/tex] is wavelength in vacuum and n is refractive index of the medium.

[tex]n=\dfrac{\lambda}{\lambda_m}\\\\n=\dfrac{\lambda}{0.671\lambda}\\\\=\dfrac{1}{0.671}\\\\=1.49[/tex]

So, the medium can be PMMA (acrylic, plexiglas, lucite, perspex) which have a refractive index of 1.49.

The index of refraction of the material for which the wavelength of light is 0.671 times, the value of it in a vacuum is 1.49.

The index of refraction of a material is the ratio of wavelength of the wave in vacuum to the wavelength of the wave in the given medium.

The index of refraction is inversely proportional to the wavelength. It can be find out using the following formula.

[tex]n=\dfrac{\lambda}{\lambda_m}[/tex]

Here, (λ) is the wavelength in vacuum and (λm) is the wavelength in a medium.

The index of refraction of a material for which the wavelength of light is 0.671 times its value in a vacuum (0.671×λ).

Plug in the values in the above formula,

[tex]n=\dfrac{\lambda}{0.671\times\lambda}\\n=1.49[/tex]

Thus, the index of refraction of the material for which the wavelength of light is 0.671 times, the value of it in a vacuum is 1.49.

Answer:

The correct option is  D

Explanation:

From the question we are told that

  The maximum electric field strength is  [tex]E = 1.0 *10^{11} \ V/m[/tex]

   The  area is  [tex]A = 5.0 \ mm^2 = 5.0 *10^{-6} \ m^2[/tex]

Generally the force the laser applies is mathematically represented as

       [tex]F = \epsilon_o * E ^2 * A[/tex]

Here  [tex]\epsilon_o = 8.85*10^{-12} C/(V \cdot m)[/tex]

      [tex]F = 8.85*10^{-12} * (1.0 *10^{11}) ^2 * 5.00*10^{-6 }[/tex]

Answer:

(B)  1.23 x 10⁴ J

Explanation:

Given;

radius of the sphere, r = 7.0 m

diameter of the sphere, d = 2r = 14.0 m

mass of the person sitting on the sphere, m = 90.0 kg

The gravitational potential energy of the person is given by;

P.E = mgh

where;

g is acceleration due to gravity = 9.8 m/s²

h is the height above the ground level = d = 14.0 m

P.E = mgh

P.E = (90)(9.8)(14)

P.E = 12348 J

P.E = 1.2348 x 10⁴ J

Therefore, the gravitational potential energy of the person is 1.2348 x 10⁴ J

Answer:

Y = 78.13 x 10⁹ Pa = 78.13 GPa

Explanation:

First we will find the centripetal force acting on the wire as follows:

F = mv²/r

where,

F = Force = ?

m = mass of rock = 0.34 kg

v = speed = 19 m/s

r = length of wire

Therefore,

F = (0.34)(19)²/r

F = 122.74/r  

now, we find cross-sectional area of wire:

A = πd²/4

where,

A = Area = ?

d = diameter of wire = 1 mm = 0.001 m

Therefore,

A = π(0.001)²/4

A = 7.85 x 10⁻⁷ m²

Now, we calculate the stress on wire:

Stress = F/A

Stress = (122.74/r)/(7.85 x 10⁻⁷)

Stress = 1.56 x 10⁸/r

Now, we calculate strain:

Strain = Δr/r

where,

Δr = stretch in length = 2 mm = 0.002 m

Therefore,

Strain = 0.002/r

now, for Young's modulus (Y):

Y = Stress/Strain

Y = (1.56 x 10⁸/r)/(0.002/r)

Y = 78.13 x 10⁹ Pa = 78.13 GPa
