Suppose we replacebothhover pucks with pucks that are the same size as the originals but twice as massive. Otherwise, we keep the experiment thesame. Compared to the pucks in the video, this pair of pucks will rotateHint 1.How to approach the problemThis question asks you to relate the mass of a rotating object to the object’s angular speed(rate of rotation).You can do that using angular momentum:. In this equation, the moment of inertiais the "mass" term, equivalent toin the equation forlinear momentum.So, how does the pucks moment of inertiarelate to their mass? Is the relationship linear ()? Or is it quadratic () or inverse square()? To see the answer, try writing the general equation that defines.Now, how will doubling the mass of the pucks affect,, and?

Answers

Answer 1

When the mass of an object is doubled, the moment of inertia of the object is also doubled. This is because the moment of inertia of an object is proportional to the mass of the object. In the equation for angular momentum, $L = I\omega$, the moment of inertia $I$ is the "mass" term, and it is proportional to the mass of the object.

If we double the mass of the pucks in the experiment, the moment of inertia of the pucks will also be doubled. This means that the angular momentum of the pucks will be doubled, since $L = I\omega$.

However, the angular speed $\omega$ of the pucks will remain the same, since it is not directly affected by the mass of the pucks.

Therefore, the pair of pucks that are twice as massive as the original pucks will have the same angular speed but a higher angular momentum. This means that the pucks will rotate at the same rate but with more momentum, making them harder to stop or change direction.

An old version of stellar evolution, popular at the beginning of the twentieth century, maintained that stars begin their lives as large, cool spheres of gas, like the giant stars on the H-R diagram. They then contract and heat up under the pull of their own gravity to become hot, bright blue O stars. For the remainder of their lives they lose energy, becoming dimmer and redder with age. As they slowly move down the main sequence, they eventually end up as cool, dim red M stars. Explain how observations of stellar clusters, plotted on the H-R diagram, contradict this idea.

Answers

Every star goes through distinct evolutionary stages that are determined by  its internal structure and method of energy production depending on its initial mass. The temperature and luminosity of the star change with each of these stages, and as the star develops, it can be seen moving to various locations on the HR diagram.

One of the most crucial tools for studying stellar evolution is the HR diagram, also known as the Hertzsprung-Russell diagram. It was independently created by Ejnar Hertzsprung and Henry Norris Russell in the early 1900's and plots either the colour of stars against their absolute magnitude or the temperature of stars against their luminosity.

The HR diagram is dominated by the main sequence, which extends from the upper left to the bottom right. In their cores, stars spend about 90% of their lives converting hydrogen to helium.

Low-mass stars reach their final evolutionary stage as white dwarf stars.

It translates into the amount of work required to move a charge from one point between two points in a static electric field. Volt is the name of the voltage-derived unit in the International System of Units. 166 Joules per coulomb, or 1 volt equals 1 joule (of work) per 1 coulomb, is how work per unit of charge is expressed in SI units (of charge). Power and current were used in the previous SI definition for the volt, the quantum Hall as well as Josephson effect was introduced in 1990, and as of 2019 fundamental physical values obtained have been used in the definition of any and all SI units as well as derived units.

The average voltage induced in the coil can be calculated using Faraday's Law:
V = (B*A*N*Δt)/t
V = (0.11 T *(7.9 cm)^2 * 2,786 turns * 0.5 s)/0.5 s

A high-speed bullet train accelerates and decelerates at the rate of 10 ft/s2. Its maximum cruising speed is 90 mi/h. (a) What is the maximum distance the train can travel if it accelerates from rest until it reaches its cruising speed and then runs at that speed for 15 minutes?(b) Suppose that the train starts from rest and must come to a complete stop in 15 minutes. What is the maximum distance it can travel under these conditions?(c) Find the minimum time that the train takes to travel between two consecutive stations that are 45 miles apart.(d) The trip from one station to the next takes at minimum 37.5 minutes. How far apart are the stations?

Answers

The train can go a maximum distance of 119671.2 feet if it starts off at a slow speed, accelerates until it reaches cruising speed, and then maintains that speed for 15 minutes.

The train travels 117057.6 feet when it starts off at rest and must come to a complete halt in 15 minutes. Between two consecutive stops that are 45 miles apart, the train travels in 30.22 minutes overall. The distance between the stations is 55.92 miles.

This condition can be broken down into two kinematic equations:

d = 1/2*10*t2 for acceleration (No initial velocity) UNITS: foot, s

Knowing the ultimate velocity allows us to calculate t as follows: v=90mph=132ft/s=10*t, which equals t=13.2s.

d = 5*(13.2^2) = 871.2 ft

Constant speed for 15 minutes = 900s

 d = 132ft/s * 900s = 118800 ft

 Total Distance: 119671.2 ft = 22.665 mi

Split this situation up into 3 parts, Maximum distance would be maximum cruising time:

Accelerating to cruising speed: d = 871.2 ft, t = 13.2s

Decelerating from cruising speed:

d = 5*(13.2^2) = 871.2 ft

900 seconds at constant speed for 15 minutes

d = 132 feet per second multiplied by ninety seconds equals 118,800 feet.

Total distance: 22.665 miles or 119671.2 feet.

Divide this circumstance into three pieces. The maximum distance corresponds to the maximum cruising time:

Cruising speed acceleration: d = 871.2 ft, t = 13.2 s

Deceleration from cruise: d = -5*t2 + 132*t, v = 0 = -10*t + 132, t = 13.2s, d = 871.2ft

We know that while cruising, t = 900s - 13.2s - 13.2s = 873.6s, and d = 132*873.6 = 115315.2ft.

117057.6 feet or 22.17 miles total.

Similar to part b, but with the cruise distance known and the requirement to solve for time now (minimum time is maximum speed, so maximum cruising time).

d = 871.2 feet, t = 13.2 seconds, accelerating

d = 871.2 feet, t = 13.2 seconds, decelerating

When cruising, the distance is 45 miles and the altitude is 871.2 feet. The altitude is then multiplied by 1742.4 feet to get the total altitude, which is 235857.6 feet.

t = 235857.6/132 = 1786.8s

Total time: 1786.8 + 12.2 + 12.2 = 1813.2s or 30.22 minutes.

This portion is identical to part c, except that the order is reversed:

d = 871.2 feet, t = 13.2 seconds, accelerating

decreasing: d = 871.2 feet, t = 13.2 seconds

Traveling: t = 2250 - 26.4 = 2223.6s d = 132*2223.6 = 293515.2ft

2tη_p = λ/2

=> t = λ/2 × (1/2η_p)

=> t = λ/(4η_p)

=> t = 470/(4 × 1.49)

=> t = 78.85 nm

Which of the following best reduces atmospheric distortion?
adaptive optics

Answers

The best reduces atmospheric distortion is through adaptive optics.

Optical aberrations can be fixed using a technology called adaptive optics (AO). The work that led to the Nobel Prize-winning discovery of a supermassive compact object at the center of our galaxy was made possible by a method that was initially devised to account for the blurring effect of atmospheric turbulence on images in ground-based observatories. We can research the functioning of the visual system and evaluate ocular health in the microscopic domain when AO is employed to compensate for the eye's defective optics.

By detecting retinal changes at the cellular level, AO allows us to adjust for the eye's imperfect optics. AO has expanded the capabilities of imaging in thick tissue specimens, such as when examining neuronal processes in the brain, by correcting for sample-induced blur in microscopy.

a steel ball is dropped onto a very hard floor. over and over again, the ball rebounds to its origional height (assume that no energy is lost during the collision with the floor). is the motion of the ball simple harmonic motion?

Answers

Yes, the motion of ball is following simple harmonic oscillation.

An equilibrium position exists for harmonic motion. No force is present there. The force acting on the mass attempts to bring the mass back to equilibrium if it is deflected from its equilibrium position. Given that the displacement from equilibrium is measured by x and the force is linear, F = -k * x. K is equal to newtons/meter for springs because k = force/distance. Because of linearity, force and displacement are inversely proportional. Small force, small displacement. Strong force, strong displacement. The period of the simple harmonic oscillator is independent of amplitude because of this proportionality.

No matter where the ball is, there is a constant downward force applied by the bouncing object. Only at the bottom of the bounce is there a significant upward force. Nearly all of the damping is at the bounce point. The amplitude has a strong bearing on the period.

calculate the orbital period of a comet with a perihelion distance of 0.5 au and aphelion in the oort cloud, at a distance of 50,000 au from the sun.

Answers

The value of the major axis of the comet will be [tex]A=50AU[/tex]and the major axis of the comet is the sum of aphelion distance [tex]\left(a_y\right)[/tex] and perihelion distance [tex]$\left(p_y\right)$[/tex] is [tex]49 AU[/tex]

It is given that,

The value of the perihelion distance of 0.5 au and aphelion in the Oort cloud, at a distance of 50,000 au from the sun.

We need to determine the value of the orbital period of a comet

As we know,

Half of the semi-major axis is the radius of the orbit.

[tex]$$\begin{aligned}a & =\frac{50000 \mathrm{~A} \cdot \mathrm{U}}{2} \\& =25000 \mathrm{~A} . \mathrm{U}\end{aligned}$$[/tex]

From the Kepler's third law, the square of the period of a comet is directly proportional to the cube of its radius of the orbit.

So, applying the above concept.

We will get,

[tex]$$\begin{aligned}p^2 & =a^3 \\p & =[a]^{\frac{3}{2}} \\& =[25000 \mathrm{~A} U]^{\frac{3}{2}} \\& \approx 4 \times 10^6 \text { years (or) } 4.0 \text { million years }\end{aligned}$$[/tex]

(2) Using keplers third law calculate the semi major axis of the comet can be calculated as follows

[tex]$$\begin{aligned}p^2 & =a^3 \\a & =[p]^{\frac{2}{3}} \\& =[125]^{\frac{2}{3}} \\& =25 \mathrm{~A} . \mathrm{U}\end{aligned}$$[/tex]

So, the value of the major axis of the comet will be:

[tex]$$\begin{aligned}A & =2 \mathrm{a} \\& =2(25 \mathrm{~A} \cdot \mathrm{U}) \\& =50 \mathrm{~A} \cdot \mathrm{U}\end{aligned}$$[/tex]

Major axis of the comet is the sum of aphelion distance [tex]\left(a_y\right)[/tex] perihelion distance [tex]$\left(p_y\right)$[/tex].

[tex]$$\begin{aligned}A & =a_y+p_y \\p_y & =A-a_y \\& =50 \mathrm{~A} . \mathrm{U}-1.0 \mathrm{~A} . \mathrm{U} \\& =49 \mathrm{A.U}\end{aligned}$$[/tex]

f a force of 120 n acting 0.29 m from the axis of rotation is balanced by another force of 92 n (causing no motion), what is the moment arm of the second force?

Answers

The moment arm of the second force is 0.29 m.

What is moment?
A moment is just a mathematical expression used in physics that involves the product of a physical quantity and a distance. Moments refer to the physical quantities that are dispersed from the reference point and are typically defined with regard to a fixed reference point. The moment thus explains the position or arrangement of the quantity. For instance, the moment of force, also known as torque, is the result of the force acting on an object and the object's distance from of the reference point. In theory, a moment can be created by multiplying any physical quantity by a distance. Forces, masses, and electrically charged distributions are frequently used units.

The moment arm of the second force is the distance from the axis of rotation to the point at which the force is acting.
Since the two forces are in equilibrium, meaning that they have cancelled each other out, the distance from the axis of rotation to the point at which the second force is acting (the moment arm) must be equal to the distance from the axis of rotation to the point at which the first force is acting (0.29 m).
Thus, the moment arm of the second force is 0.29 m.
