The colors can be able to pass through if they have the same wavelength while the rest are absorbed.

Colors are transmitted through a material by the selective absorption, reflection, and transmission of light. Different colors of light have different wavelengths and frequencies, and different materials interact with light in different ways.

a. when an object changes position relative to a reference point is motion.

In physics, motion is a relation of a body's position or orientation over time. Translation is characterized as movement along a line or a curve. Rotation is a motion that adjusts a body's orientation.

Motion is impeded or halted by the force of friction. When two components rub into one another, they create friction, which is a resistance to motion (the sled and the snow, for instance). Even air friction happens. An object can move or accelerate, slow down or descend, cease, or change direction as a result of force.

If it's a monatomic gas system the difference in temperature is about 0.212 K.

Helium, neon, argon, krypton, radon, xenon, and neon are a few examples of monatomic gases (the noble gases).

Answer:

The escape speed from a spherical object can be calculated as v_esc = √(2GM/R), where G is the gravitational constant, M is the mass of the object, and R is the radius.

Setting v_esc = c, the speed of light, and solving for R:

R = GM/c^2 = (6.67 x 10^-11 m^3 kg^-1 s^-2)(5.97 x 10^24 kg)/(3 x 10^8 m/s)^2

R = 1.20 x 10^8 m = 1,200,000,000 mm

So the radius of the Earth would need to be approximately 1,200,000,000 millimeters (or 1.2 x 10^8 meters) for its escape speed to equal the speed of light.

By doing this, the plug is kept from being yanked out of the socket by the cord's or plug's weight. Additionally, it enhances the connection between both the socket and the outlet.

Plugs have holes that are used to hold them in place inside sockets. Historically, sockets contained bumps. The purpose of these bumps was to fit inside the perforations. It would have been quite simple to simply take the plug out of the connection if there weren't any bumps and holes.

This stops the mass of the plug or wire from pulling the plug out of the socket. The contact between both the plug and the output is also improved.

The radius of curvature of the track at the instant the train is 6s into the curve and experiences a horizontal acceleration of 2 m/s2 is 266m.

To calculate the radius of curvature, we need to consider the relationship between the horizontal acceleration, velocity, and radius. The formula for centripetal acceleration is given as a = v^2/r, where a is the horizontal acceleration, v is the velocity, and r is the radius of curvature.

Since the train slows down with constant deceleration from 100 km/h to 50 km/h in 12s, we can calculate the average velocity for the 6s time frame, which is (100 + 50)/2 = 75 km/h.

Converting this to m/s, we get 75 km/h = 20.83 m/s. Plugging this into the formula, we have

Momentum is the tendency of a moving object to continue its motion at a constant speed. Momentum is also a quantity related to the mass and speed of an object. Meaning, momentum is a vector quantity which is the product of the velocity and mass of a particle or object. The bigger an object, the greater the momentum will be. The faster an object is moving, the greater its momentum will be. Momentum is a vector quantity that is in the same direction as the velocity of an object.

Linear momentum, also known as momentum, is a vector quantity that describes the motion of an object. It is defined as the product of an object's mass and its velocity. The unit of momentum is kilogram meter per second (kg m/s). Linear momentum is a conserved quantity, meaning that the total momentum of a system of objects remains constant if no external forces act upon it. This principle is known as the law of conservation of momentum and it is a fundamental concept in classical mechanics.

The momentum of an object can be changed by applying a force on it, causing the object to accelerate. The greater the mass of an object and the faster it is moving, the greater its momentum.

The 96th harmonic of the stopped pipe has the same frequency as the third harmonic of the open pipe.

The frequency of a harmonic in an organ pipe depends on the length of the pipe, the type of end (open or stopped), and the harmonic number.

For an open pipe, the frequency of the nth harmonic is given by:

f_n = n * v / 2L

where n is the harmonic number, v is the speed of sound in the medium (air), and L is the length of the pipe.

For a stopped pipe, the frequency of the nth harmonic is given by:

f_n = n * v / 4L

where n is the harmonic number, v is the speed of sound in the medium (air), and L is the length of the pipe.

Given that the stopped pipe has a length of 16 times shorter than the open pipe, we can write:

L_stopped = L_open / 16

Comparing the frequency of the third harmonic of the open pipe with the frequency of some harmonic of the stopped pipe:

f_3,open = 3 * v / 2L_open = f_n,stopped = n * v / 4L_stopped

Solving for n, we get:

n = (3 * 2L_open) / (4 * L_stopped) = 3 * 2 * 16 = 96

The distance from the starting point to the ending point is √(49225 - 15400 * cos(C))

To find the distance from the starting point to the ending point, we need to use the law of cosines.

d = √(AB² + BC² - 2 * AB * BC * cos(C))

where d is the distance from A to C, AB is the distance traveled on the first bearing, BC is the distance traveled on the second bearing, and C is the angle between the two bearings.

Given AB = 55 km and BC = 140 km, we can use the formula to calculate d:

d = √(55² + 140² - 2 * 55 * 140 * cos(C))
