The expression for a perfectly inelastic collision,

\(m_1v_1 + m_2v_2 = (m_1+m_2)v_f\)

Therefore,

\(v_f = \frac{m_1v_1 + m_2v_2}{(m_1+m_2)} \\\\v_f = \frac{(2*2)+(0.2*-8)}{2+0.2}\\\\v_f = 1.09m/s\)

Since the bat and the bug fly towards each other, and after some time the bat swallows the bug, it is said to be a condition of perfectly inelastic collision.

The kinetic energy of the bat before it swallows the bug is,

\(KE_b = \frac{1}{2}m_1v_1^2\\\\KE_b = \frac{1}{2}2*2^2\\\\KE_b = 4gm^2/s^2\)

Kepler's laws played a crucial role in the development of modern astronomy and our understanding of the solar system.

Kepler's laws are a set of three empirical laws that describe the motion of planets around the sun, based on the observations of the German astronomer Johannes Kepler in the early 17th century. The three laws are as follows:

Kepler's First Law, or the Law of Orbits: The orbits of the planets around the sun are ellipses, with the sun at one of the two foci.

This law implies that the distance between the planet and the sun varies throughout the planet's orbit, with the closest distance known as the perihelion and the farthest distance known as the aphelion.

Kepler's Second Law, or the Law of Areas: A line that connects a planet to the sun sweeps out equal areas in equal times.

This law means that a planet moves faster when it is closer to the sun and slower when it is farther away, but the area swept out by the line connecting the planet to the sun in a given time interval remains constant.

Kepler's Third Law, or the Law of Harmonies: The square of the period of a planet's orbit is proportional to the cube of the average distance between the planet and the sun.

This law expresses a mathematical relationship between the period (the time it takes for a planet to complete one orbit around the sun) and the average distance of the planet from the sun.

Kepler's laws were instrumental in the development of modern astronomy and our understanding of the solar system. They laid the foundation for the laws of motion and universal gravitation developed by Sir Isaac Newton, and led to significant advancements in the study of celestial mechanics.

Here,

Kepler's laws are a set of three empirical laws that describe the motion of planets around the sun. Here are the formulas for each of the three laws:

Kepler's First Law (Law of Orbits): The orbits of the planets around the sun are ellipses, with the sun at one of the foci.

This law can be written as an equation for an ellipse:

((x-h)² / a²) + ((y-k)² / b²)= 1

where:

(h, k) is the center of the ellipse

a is the semi-major axis of the ellipse

b is the semi-minor axis of the ellipse

Kepler's Second Law (Law of Areas): The line connecting a planet to the sun sweeps out equal areas in equal times.

This law can be written as an equation:

A / t = constant

where:

A is the area swept out by the planet in a given time t is the time it takes for the planet to sweep out that area

Kepler's Third Law (Law of Harmonies): The square of the period of a planet's orbit is proportional to the cube of its average distance from the sun.

This law can be written as an equation:

T*2 = (4π*2 / G(M+m)) * r*3

where:

T is the period of the planet's orbit

M is the mass of the sun

m is the mass of the planet

r is the average distance between the planet and the sun

G is the gravitational constant

Answer:

Two atoms could repell each other if they have the same charge... A positive and a positive atom or a negative and a negative atom

Explanation:

True. In GMAW (Gas Metal Arc Welding), the amperage is controlled by adjusting the wire feed speed.

GMAW is a welding process that uses a continuously fed wire electrode to join two pieces of metal together. The wire electrode is fed through a welding gun and is melted by an electric arc, which produces a pool of molten metal that solidifies to form a weld.

The amperage in GMAW is controlled by adjusting the wire feed speed, which is the rate at which the wire electrode is fed through the welding gun. Increasing the wire feed speed increases the amperage, while decreasing the wire feed speed decreases the amperage. This allows the welder to control the heat input and penetration of the weld.

As the wire feed speed increases, so does the amperage, and vice versa.

Here are a few possible approaches to regulation: Establishing Maximum Work Hours: Implementing regulations that define maximum work hours per shift or per week can help prevent excessive sleep deprivation. Setting limits on consecutive working hours and ensuring sufficient rest periods between shifts can promote better sleep patterns. Adequate Rest Periods: Ensuring that individuals have sufficient time for rest and recovery between shifts is crucial. Mandating minimum periods of uninterrupted rest can help mitigate the effects of sleep deprivation and allow for sufficient sleep. Education and Training: Providing comprehensive education and training on sleep hygiene, fatigue management, and the potential consequences of sleep deprivation can increase awareness among professionals in these careers. It can empower individuals to take proactive steps to manage their sleep and prioritize their well-being. Workplace Support: Employers can play a significant role in supporting employees by implementing policies and practices that prioritize sleep health. This can include providing designated rest areas, promoting healthy sleep habits, and encouraging open communication about sleep-related concerns. Regular Health Assessments: Regular health assessments and screenings that include evaluation of sleep patterns and sleep disorders can help identify individuals who may be at risk of chronic sleep deprivation. This can allow for early intervention and appropriate support measures. Regulations should be developed through collaboration among stakeholders, including professionals in the respective fields, labor organizations, employers, and regulatory bodies. It is important to strike a balance between the needs of the job and the well-being of the individuals performing those jobs. Ultimately, the goal should be to create a work environment that recognizes the importance of sleep and takes proactive measures to mitigate the negative effects of sleep deprivation, ensuring the safety, health, and overall well-being of individuals in these careers.

The length of the third side is

     \(c =8.82 \  m \)

The tangent of the angle for which 6.9 m is the opposite side is

\(k = 1.256\)

Explanation:

From the question we are told that

The first side is a = 6.9 m

The second side is b = 5.5 m

Generally apply Pythagoras theorem

\(c^2 = a^2 + b^2\)

=> \(c = \sqrt{a^2 + b^2 }\)

=> \(c = \sqrt{6.9^2 + 5.5^2 }\)

=> \(c =8.82 \ m \)

From sin rule we have that

\(\frac{c}{sin(\theta )} = \frac{a}{sin (\beta )}\)

Generally from a right triangle the angle \(\theta = 90\)

So

\(\frac{8.82}{sin(90 )} = \frac{6.9}{sin (\beta )}\)

=> \(\beta = sin ^{-1}[\frac{6.9}{8.82} ]\)

=> \(\beta =51.47^o\)

Generally the tangent of the angle for which 6.9 m is the opposite side is mathematically represented as

\(k = tan (\beta )\)

       \(k  =  tan (51.47 )\)

       \(k  = 1.256\)

(a) The tangential speed of the rim of the disk is found to be 48.3 m/s and (b) On increasing the operating speed, the period of rotation of the disk is now  0.0314 seconds.

(a) To determine the tangential speed of the rim of the disk, we can use the formula,

v = ωr, tangential speed is v, ω is the angular velocity is ω, and radius of the disk is r. Given ω = (2.10) 10⁴ rad/s and r = 2.30 mm = 0.00230 m, we can calculate,

v = (2.10(10⁴)rad/s)(0.00230m)

v ≈ 48.3 m/s

Therefore, the tangential speed of the rim of the disk is approximately 48.3 m/s.

(b) To find the period of rotation, we can use the formula,

T = 2π / ω, period of rotation is T and angular velocity is ω.

Given v = 255 m/s, we can rearrange the formula to solve for ω,

ω = v / r

Substituting the values, we have,

ω = 255 m/s / 0.00230 m

ω ≈ 111086.96 rad/s

Now we can calculate the period,

T = 2π / ω

T = 2π / (111086.96 rad/s)

T ≈ 0.0314 seconds

So, the period of rotation is now 0.0314 seconds.

Explanation:

Coefficient of kinetic friction is the resistive force that opposes the motion of a body as it moves and is in contact with another body.

It is found by dividing the frictional force by the normal force.

Explanation:

Newton's law of universal gravitation states that every object attracts every other object with a force. For any two objects, this force is directly proportional to the mass of each object. The greater the masses, the greater the force of attraction between them. Newton also deduced that this force decreases as the square of the distance between the centers of the objects increases. The farther away the objects are from each other, the less the force of attraction between them.
