An electromagnetic wave called a light wave can go through the vacuum of space. Electric charges vibrate and create light waves. A transverse wave with both an electric and a magnetic component is known as an electromagnetic wave.

There is a huge variety of frequencies for electromagnetic waves. The electromagnetic spectrum is a continuous range of frequencies. White is the color that is seen when the entire visible light spectrum is received by your eye at once. Thus, visible light is sometimes referred to as white light. Technically speaking, white is not a color at all, but rather the combination of all the colors of the visible light spectrum

Radiation beam is energy in the form of waves of particles. There are two forms of radiation which are  non-ionizing and ionizing.

Non-ionizing radiation has less energy than ionizing radiation; it does not possess enough energy to produce ions.

Ionizing radiation is capable of knocking electrons out of their orbits around atoms, upsetting the electron/proton balance and giving the atom a positive charge.

Alpha radiation consists of alpha particles that are made up of two protons and two neutrons each and that carry a double positive charge. Due to their relatively large mass and charge, they have an extremely limited ability to penetrate matter.

The collision is elastic, the final velocities v1 and v2 of particles 1 and 2 (v₁, v₂) = [(v/3), (4v/3)] Or (v₁, v₂) = (v, 0)

In elastic collisions, the momentum and kinetic energy is usually conserved.

The momentum before collision = momentum after collision

And

Kinetic energy before collision = Kinetic energy after collision

Momentum of object 1 before collision = (2m)v = 2mv

Momentum of object 2 before collision = (m)(0) = 0

Momentum of object 1 after collision = (2m)(v₁) = 2mv₁

Momentum of object 2 after collision = (m)(v₂) = mv₂

So, we have

2mv = 2mv₁ + mv₂

2v = 2v₁ + v₂

v₂ = 2v - 2v₁ (eqn 1)

Kinetic energy of object 1 before collision = (1/2)(2m)(v²) = mv²

Kinetic energy of object 2 before collision = (1/2)(m)(0²) = 0

Kinetic energy of object 1 after collision = (1/2)(2m)(v₁²) = mv₁²

Kinetic energy of object 2 after collision = (1/2)(m)(v₁²) = (mv₂²/2)

So, we have,

mv² = mv₁² + (mv₂²/2)

v² = v₁² + (v₂²/2)

2v² = 2v₁² + v₂² (eqn 2)

Substitute (v₂ = 2v - 2v₁) from (eqn 1) into (eqn 2)

2v² = 2v₁² + (2v - 2v₁)²

2v² = 2v₁² + 4v² - 8vv₁ + 4v₁²

6v₁² - 8vv₁ + 2v² = 0

6v₁² - 6vv₁ - 2vv₁ + 2v² = 0

6v₁(v₁ - v) - 2v(v₁ - v) = 0

(6v₁ - 2v)(v₁ - v) = 0

6v₁ = 2v or v₁ = v

v₁ = (v/3) or v₁ = v

If v₁ = (v/3)

From (eqn 1)

v₂ = 2v - 2v₁

v₂ = 2v - 2(v/3)

v₂ = 2v - (2v/3)

v₂ = (4v/3)

If v₁ = v,

From eqn 1,

v₂ = 2v - 2v₁

v₂ = 2v - 2v = 0

What is equilibrium?

Equilibrium, in physics, the state of a system when neither its state of motion nor its internal energy state tend to change over time. A simple mechanical body is in equilibrium when it experiences neither linear nor angular acceleration. This state will continue indefinitely unless disturbed by an external force. Equilibrium occurs for a single particle when the vector sum of all forces acting on the particle is zero. A rigid body (which by definition differs from a particle by its properties of extension) is in equilibrium when, in addition to the states listed above for particles, the vector sum of all torques acting on the body is equal to zero, Its state of rotational motion remains constant. An equilibrium is said to be stable when a small externally induced displacement from that state produces a force opposing the displacement tending to bring the body or particle back into equilibrium. Examples include weights suspended from springs or bricks placed on a flat surface.

Tension is described stress transmitted axially by a cord, rope, chain, or similar object, or through the ends of a rod, truss, or similar three-dimensional object. Stresses can also be described as pairs of acting and reaction forces acting at each end of the element. Tension may be the opposite of compression. At the atomic level, a restoring force can create what is called stress when atoms or molecules are pulled apart and gain potential energy while the restoring force is still present. An end of a cord or rod under such tension can pull on the object to which it is attached to return the cord or rod to its relaxed length.

According to Snyder, human beings generally differ significantly in their capacities and motivations for engaging in expressive controls (see dramaturgy).

Self-monitoring is a personality feature that is used to describe the capacity to control conduct to meet social circumstances. In order to assure proper or desired public appearances, people who are concerned with their expressive self-presentation (see impression management) prefer to pay great attention to their audience. Self-monitors make an effort to comprehend how other people and groups will view their behaviour.

The maximum power that the siren can put out is 4.921 x 10^8 Watts.

The maximum power that the siren can put out will depend on the sound pressure level (SPL) at a distance of 177 m from the siren. The SPL is determined by the inverse square law, which states that the intensity of a sound wave decreases in proportion to the square of the distance from the source.

Therefore, the SPL at a distance of 177 m from the siren can be calculated using the following equation:

SPL = SPL_0 - 20 log (177/1)

where SPL_0 is the initial SPL at a distance of 1 m from the siren.

Assuming that the SPL at 1 m from the siren is 130 dB, then the SPL at 177 m from the siren is:

SPL = 130 - 20 log (177/1) = 121 dB

Since the safety regulations require that the SPL does not exceed 121 dB at a distance of 177 m from the siren, the maximum power that the siren can put out is the power required to generate a SPL of 121 dB at a distance of 177 m.

The power required can be calculated using the following equation:

Power = 10^(SPL/10) * (4 * pi * (177 ^2))

where pi = 3.14

Therefore, the maximum power that the siren can put out is:

The coefficient of kinetic friction between the horizontal surface and the bullet-block system is 4m/s .

The coefficient of kinetic friction is a numerical value that quantifies the intensity of friction of one sliding surface relative to another.

Also known as the coefficient of kinetic friction, it measures the extent of material grip between a moving object and its contact surface.

Recall that there are three types of dry friction: static friction, kinetic friction, and rolling friction.

Although the coefficient of kinetic friction is higher than the coefficient of rolling friction, it is still lower than the coefficient of static friction.

The force of static friction is greater than kinetic and rolling friction.

Therefore, more force is required to initiate motion when the object is at rest, but once motion is initiated, less force will be required to maintain the motion.

Rolling objects usually have the lowest coefficient of friction due to the minimal contact area.
