The colors can be able to pass through if they have the same wavelength while the rest are absorbed.
How are colors transmitted through a material?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.
Some materials, such as a prism, can split light into its component colors, while others, such as a colored filter, can absorb certain colors and allow others to pass through.

what is the speed of the lander just before it touches the surface? the acceleration due to gravity on the moon is 1.6 m/s2 m / s 2 .
The speed of the lander just before it touches the surface is 4.3 m/s.
What are the equations of motion?A mathematical formula that explains the location, velocity, or acceleration of a body in relation to a specific frame of reference is known as an equation of motion. The basic equation of motion in classical mechanics is Newton's second law, which states that the force F acting on a body is equal to the mass m of the body multiplied by the acceleration an of its center of mass, F = ma.
If the force acting on a body is known as a function of time, the velocity and position of the body as functions of time can potentially be deduced from Newton's equation via the integration method. A falling body, for example, accelerates at a constant rate, g. The rate of change of velocity with respect to time is defined as acceleration.

By shaking one end of a stretched string, a single pulse is generated. the traveling pulse involves a transport of energy and momentum.
The definition of energy is "capacity to do work, which is ability to apply force causing displacement of an object." Energy is just the force that moves objects, despite this definition's seeming complexity.
Potential and kinetic energy are the two different categories. The best approach to understand them is to think of potential energy as occurring before an action and kinetic energy as occurring during an action. Consider raising your physics textbook in the air. Simply due of its elevated elevation, it could fall. If you drop the textbook, the potential energy is transformed into kinetic energy, which is the energy that drives the movement.

In optics, magnification refers to the image's size in relation to the item that produced it. The ratio of the image length to the object length, as measured in planes perpendicular to the optical axis, is referred to as linear magnification, also known as lateral or transverse magnification. An inverted image is shown by a linear magnification value that is negative. The size-increasing factor, as determined along the optical axis, is known as longitudinal magnification.

if the electric field is 108 n/c at a distance of 59 cm from a point charge q, what is the value of q (in c)? (enter the magnitude.)
If the electric field is 108 n/c at a distance of 59 cm from a point charge q, the charge on the point charge is 9.98 x [tex]10^{-19}[/tex] Coulombs.
We can use the equation for the electric field produced by a point charge to find the charge:
E = k * q / [tex]r^{2}[/tex]
where,
E = the electric field, equal to 108 N/C
k = the Coulomb constant, equal to 8.99 x [tex]10^{9}[/tex] N [tex]m^{2}[/tex] / [tex]C^{2}[/tex]
q = the charge
r = the distance from the point charge, equal to 59 cm = 0.59 m
Rearranging the equation to solve for q, we get:
q = E * [tex]r^{2}[/tex] / k
Plugging in the values, we get:
q = 108 N/C * [tex](0.59 m)^{2}[/tex] / 8.99 x [tex]10^{9}[/tex] N [tex]m^{2}[/tex] / [tex]C^{2}[/tex] )

in getting ready to slam-dunk the ball, a basketball player starts from rest and sprints to a speed of 6.26 m/s in 2.20 s. assuming that the player accelerates uniformly, determine the distance he runs.
The basketball player runs a distance of 12.54 meters to reach the speed of 6.26 m/s.
The average velocity of the basketball player can be calculated using the equation:
v = v0 + a * t
Where v is the final velocity, v0 is the initial velocity (0 m/s), a is the acceleration, and t is the time taken. We can rearrange this equation to solve for a:
a = (v - v0) / t = (6.26 m/s - 0 m/s) / 2.20 s = 2.83 m/s^2
Next, we can use the equation for distance travelled under constant acceleration:
d = v0 * t + 0.5 * a * t^2
Plugging in the given values, we get:
d = 0 * 2.20 s + 0.5 * 2.83 m/s^2 * 2.20 s^2 = 12.54 m

The velocity of the players just after the tackle 4.027 m/s and the change in kinetic energy will be 92 J
The system's overall momentum is conserved in an inelastic collision because the two bodies travel at the same speed.
Assuming v as the final speed, we obtain the following by maintaining momentum:
(m + M)v = mu - MU
where
m = 95 kg is the fullback's mass
M = 90 kg is the opponent's mass.
u = 5 m/s for the fullback's pace
opponent's speed, U = 3 m/s
The opponent's momentum is negative since he must be travelling in the opposite direction from the fullback.
(m + M)v = mv + Mv
95×5 + 90×3 = (90 +95)v
205 = 185v
v = 4.027 m/s
Consequently, both players move at a 4.027 m/s speed.
Similarly final KE of the player
KE = 1/2 (m+M) V²
KE = 1/2 (95+90)x 4.027 ²
KE = 1500 J
so the change in KE will be
1592-1500 = 92 J

When you are on a snorkeling trip. deep below the water, you look up at the surface of the water right at sunset, at a 48.59° angle to see the sun.
The crucial angle for total internal reflection is equal to the angle at which the sun appears when you are deep underwater and look up at the water's surface just before sunset.
In a clear material (like water), the critical angle is the angle of incidence when the angle of refraction is 90 degrees or greater. Beyond this critical angle, light cannot refract and is completely reflected into the denser medium (water) while it is traveling from a denser medium (water) to a less dense medium (air).
From the total internal reflection:
μ = sinθ
θ = sin⁻¹(μ)
Here, μ is the refractive index of water,
The angle is:
θ = sin⁻¹(1.333)

two carts, each of mass 2.2 kg, collide on a frictionless track. before the collision, a has a velocity of 3.1 m/s east and b has a velocity of 5.4 m/s west. what is the velocity of cart b after the collision?
Answer:
The velocity of cart B after the collision can be determined using the law of conservation of momentum.
Momentum is conserved in an isolated system, meaning that the total momentum before the collision is equal to the total momentum after the collision.
Let's call the velocity of cart B after the collision "v". The initial momentum of the system is:
m_A * v_A + m_B * v_B = (2.2 kg) * (3.1 m/s) + (2.2 kg) * (-5.4 m/s) = 0
And the final momentum of the system is:
m_A * v_A + m_B * v = (2.2 kg) * (3.1 m/s) + (2.2 kg) * v = 0
Solving for v, we find:
v = 5.4 m/s
So the velocity of cart B after the collision is 5.4 m/s.
when you take clothes out of the dryer right after it stops. the clothes often stick to your hands and arms. explain how the clothes acquires a charge
Clothes acquire a charge when taken out of a dryer due to the triboelectric effect.
The triboelectric effect is the transfer of electrons from one material to another due to friction, pressure, or contact. In a dryer, clothes are subjected to friction as they rub against each other and the drum of the dryer, which can cause electrons to transfer from one material to another. Some materials, such as synthetic fibers, have a tendency to lose electrons and become positively charged, while others, such as natural fibers, have a tendency to gain electrons and become negatively charged.
When clothes are taken out of the dryer, the negatively charged fibers will tend to stick to positively charged objects, such as skin, due to the attraction between opposite charges. This is why clothes often stick to your hands and arms after being taken out of the dryer.
