Based on the calculations, the radius of this cone is equal to 4 inches.

Mathematically, the volume of a cone is calculated by using this formula:

V = 1/3 × r²h

Where:

Making r the subject of formula, we have:

r = √(3V/πh)

Substituting the given parameters into the formula, we have;

r = √(3 × 96π/π × 18)

r = √(288/18)

r = √16

Radius, r = 4 inches.

11. The wavelength of the light ray in air is 0.589 x 10⁻⁶ m.

12. Angle of incidence for the light ray at point P is 43.23°.

13. The absolute index of refraction for medium X is 1.46

It states that the ratio of sine of angle of incidence and angle of refraction is equal to the refractive index of first medium to the second medium.

sini/sinr = n₁/n₂

11. The wavelength is related to the frequency as

λ = c/f

where c = 3 x 10⁸ m/s and frequency f = 5.09x 10¹⁴ Hz

Put the values, we get

λ = 3 x 10⁸/ 5.09x 10¹⁴

λ =0.589 x 10⁻⁶ m

Thus, the wavelength of the light ray in air is 0.589 x 10⁻⁶ m.

12. Given the angle of incidence is i, angle of refraction r =90° ,  n₂ = Refractive index of medium X = 1.46 and n₁ = Refractive index of air = 1

Substituting the values into Snell's law expression we get,

sin i= sin 90 x 1/1.46

i = 43.23 degrees

Thus, the angle of incidence is  43.23 degrees.

13. The refractive index is the ratio of speed of light  in vacuum to the speed of light in the medium X.

n = c/v₂

If v₂ is the velocity of light in medium X, then

sin i / sin r  = v₂/v₁

sin 43.23 / sin 90 =  v₂/ 3 x 10⁸

v₂ = 2.055 x 10⁸ m/s

So, the refractive index be

n = 3 x 10⁸/2.055 x 10⁸

n = 1.46

Thus, absolute index of refraction for medium X is 1.46

The new force of attraction between the two objects will be 16 times the old case.

Newton's law of gravity states that each particle having mass in the universe attracts each other particle with a force known as the gravitational force.

Gravitational force is proportional to the product of the masses of the two bodies and inversely proportional to the square of their distance.

[tex]\rm F =\frac{GmM}{r^2}[/tex]

For case 1;

r₁=r

For case 2;

r₂=r/4

[tex]\rm F'=\frac{GmM}{(\frac{r}{4})^2} \\\\ F'=16 F[/tex]

Hence,the new force of attraction between the two objects will be 16 times the old case.

The two factors that may affect the forces exerted by the pieces of tape are  the charge on the tape and distance between them.

The effect of one of the factors could be tested by altering the distance and calculating the forces between them.

A force is the push or pull which make a body to move or stop it.

a. When two objects are kept apart. they are always attracted when uncharged kept at any distance.

When the objects are charged, the force will be attractive or repulsive.

The distance between those charged objects increase or decrease in strength depending on the distance between them.

Thus, the two factors that may affect the forces exerted by the pieces of tape are the magnitude of charge on the tape and distance between them.

b. By increasing the distance between the tapes, we can find the strength of forces.

We've got m/s, which is value of distance ÷ time

(distance/time)

3 x 10^8 is:

300,000,000m/s

1km = 1000m

1hr = 3600secs

So, divide 300,000,000m by 1000 to get in km & you get:

300,000km

Now divide this value by 3600 seconds to get it in km/hr

300,000km/3600 = 83.33333333

Thus, answer is 83.3km/h

Or

8.33 x 10^1 km/h (in standard form)

(doing 83.3 recurring multipled by 1000 & 3600 gets you back to original answer. So, 83.33333...x1000x3600= 300,000,000)

The motorcycle's average velocity will be 6 m/sec. The ratio of the overall distance traveled to the total time taken by the body is the average velocity.

The average velocity is the ratio of the total distance traveled to the total time taken by the body. Its unit is m/sec.

Total distance travelled by the  motorcycle;

d=20 m+10 m

d=30 m

The average velocity is found as;

[tex]\rm v_{avg}=\frac{d}{t} \\\\ \rm v_{avg}=\frac{30}{5} \\\\ v_{avg}= 6 \ m /sec[/tex]

If the absorbed beam is monochromatic (one wavelength) then it excites the H atom to some state n.

When that state decays, some of the atoms may decay to state 1, others to state 2, and still others to state 3

The net energy emitted in such a case would depend on:

n -1, n - 2, n - 3 which would produce 3 different wavelengths

Elliptical galaxies could be formed by the collision and merging of two spiral galaxies.

Galaxy is the huge collection of stars, interstellar gases, dust particles, stones. Galaxies tend to come in two shapes such as spirals and ellipticals.

In spiral galaxies, the stars orbit in a very thin disk, and all the stars move in the same direction. Two or more spiral arms wind around the center just like a pinwheel.

Selecting a sample of about 50 spiral galaxies that have collided and in the process of merging into a single object. We took infrared images using the UH 88-inch (2.2-meter) telescope, and obtained spectra of these mergers using one of the Keck telescopes.

Infrared images are used to see, if the starlight in these objects decreases with distance from the center of the galaxy the way it does in spirals or the way it does in ellipticals. The light intensity decreases exponentially in outward direction from the centers of spirals, but it declines much more slowly with distance from the center for ellipticals. It is found that at least 45 out of 51 mergers are ellipticals.

Thus, most of these mergers really are evolving into elliptical galaxies.
