Write about planet saturn?After Jupiter, the second-largest planet in the Solar System is Saturn. It's a giant planet with a radius around nine and a half times that of the Earth.
Saturn is only one-eighth the average density of Earth, yet it is 95 times more massive due to its bigger volume.
Saturn’s bright rings are located within the Roche limit of Saturn. This supports the theory that these rings are formed from moons torn apart by tidal stress.

Summarize your findings by describing the result of adding various combinations of red, green, and blue primary light colors in equal intensities And explain the result of adding these primary colors in unequal intensities.
White color is the result of adding various combinations of red, green, and blue primary light colors in equal intensities.
What are primary colors?The three primary colors are Red, green, and blue. This implies that by additively combining the colors red, green, and blue in varied proportions the different color is obtained.
Practically all other colors may be made, and when the three primaries are mixed together in equal amounts, white is produced.
Hence white color is the result of adding various combinations of red, green, and blue primary light colors in equal intensities.

Block x of mass m slides across a horizontal surface where friction is negligible. Block x collides with block y of mass 2m that is initially at rest, as shown in figure 1. After the collision, both blocks slide together with a speed vs , as shown in figure 2. What is the kinetic energy of the two-block system before the collision?.
The kinetic energy of the two-block system before the collision will be [tex]\frac{9}{2} MV_S^2[/tex]. Momentum get conserved during the collision.
What is collision?The abrupt, violent coming together in direct contact of two bodies is known as the collision.a falling object and a floor are examples of collision.
According to the law of conservation of momentum, the momentum of the body before the collision is always equal to the momentum of the body after the collision.
According to the law of conservation of momentum;
Momentum before collision =Momentum after collision
[tex]\rm MV+2m(0)=(3M)V_S\\\\ V= \frac{3MV_S}{M} \\\\ V= 3V_S[/tex]
Velocity of the block before collision is [tex]\rm 3V_S[/tex].
The kinetic energy of the two-block system before the collision is found as;
[tex]\rm KE = \frac{1}{2} mv^2 \\\\\ \rm KE = \frac{1}{2} m(3V_S)^2 \\\\\ \rm KE = \frac{9}{2} MV_S^2[/tex]
Hence, the kinetic energy of the two-block system before the collision will be [tex]\frac{9}{2} MV_S^2[/tex].

A collision is any situation in which two or more bodies quickly exert forces on one another.
Thus, The momentum of the body prior to the contact is always equal to the momentum of the body following the impact, according to the law of conservation of momentum.
The difference between the system's total kinetic energy before and after a collision can be used to categorize collisions in physics:
The collision is said to as being inelastic if the majority or all of the total kinetic energy is lost (dissipated as heat, sound, etc. or absorbed by the objects themselves); such collisions involve the objects coming to a complete stop.
Thus, A collision is any situation in which two or more bodies quickly exert forces on one another.

Suppose the wavelength in the formula developed by balmer was 410 nm. What is the value of n?.
Answer:
The Balmer series is given by
1 / λ = R (1 / 2^2 - 1 / n^2)
where R is the Rydberg constant of 1.0968E-3 / Angstroms
(1 Angstrom = 1.0E-1 nm = 10E-10m)
Let x = (1 / 4 - 1 / n^2)
x = 1 / (R λ)
Note 410 nm = 4100 A
x = 1 / (1.0968E-3 * 4.1E3) = 1 / (1.0968 * 4.1) = .222
If we write
x = 1/4 - 1/n^2 = .222
1/n^2 = 1/4 - .222 = .0276
n^2 = 36.2
So n = 6
(Since modern terminology gives wavelengths in nanometers - it might be helpful to write R = 1.0968E7 m-1)
Which phenomena support only the wave theory of light? check all that apply. reflection refraction diffraction interference photoelectric effect
The phenomena that support only the wave theory of light are Diffraction and Interference.
What is a lightwave?Light or visible light is electromagnetic radiation within the portion of the electromagnetic spectrum that is perceived by the human eye.
The light sometimes acts like a particle and sometimes like a wave, yet the diffraction and interference are proof of the light's wave nature.
First of all, as a definition, interference is an effect caused by the superposition of two systems of waves (from two different sources). (As an example, the interference -distortion- in radio waves)
Diffraction, by the other hand, refers to several events that occur when a wave meets an obstacle. (usually described as bending of waves around obstacles like the water waves- and in other cases as the dissemination of waves, once they passed small openings)
