What are the characteristics of good quantum numbers and how do they help in solving the Schrdinger equation for a quantum system?
Good quantum numbers are properties of a quantum system that are conserved during a physical process. They include values such as energy, angular momentum, and spin. These numbers help in solving the Schrdinger equation by providing a way to simplify the equation and reduce the number of variables that need to be considered. By using good quantum numbers, the Schrdinger equation can be broken down into smaller, more manageable parts, making it easier to solve and understand the behavior of the quantum system.
How can a batter increase momentum at the plate?
A batter can increase momentum at the plate by generating a powerful weight shift from the back foot to the front foot during the swing, using the hips to drive the rotation of the body. Engaging the lower body and core muscles will help in generating bat speed and power, resulting in increased momentum on the swing. Staying balanced and maintaining good timing with the pitch will also enhance a batter's ability to generate momentum.
Which of these is the best example of transfer of momentum?
Which of what ? There's no list of choices, no examples, no suggestions, nothing to choose from.
Can objects with different masses have the same momentum?
Yes. Momentum is rigidly defined as the product of mass and velocity. Velocity describes both a speed and a direction. So let's take two metal balls. One weighs 10 kilograms (kg) and the other weighs 20kg. We roll the 10kg ball along a flat and level floor at 2 meters per second (m/s) and the 20 kg ball at 1 m/s. 10*2 = 20*1 so they have the same momentum. If you have a friend roll the balls for you to catch some distance away, making sure after a few tests to roll the lighter ball at twice the speed of the heavier ball, you will find that it "feels" as if both balls hit your hand with about the same force. Your hand is stopping each ball. That is a force which is defined as the rate of change in momentum. Stopping each ball will cause your muscles to exert about the same strength to stop each ball, even though one is moving at double the speed of the other. You will then feel that two objects can indeed travel at different speeds and yet have the same momentum. JGS
Why planets is an example of rigid bodies?
The outer planets are not a very good example of rigid bodies because of their very thick atmospheres, but it is common to assume they are rigid for calculating the angular momentum.
How a neutron star spins so fast using the law of conservation of angular momentum?
Angular momentum is the energy of spinning objects. We can calculate the energy as the product of the mass times the "moment arm", the distance from the center of rotation tims the speed of rotation. In any closed system, angular momentum is "conserved", or remains constant.On a merry-go-round on the playground, if you get it going and then move toward the center, it speeds up a little. If you move out toward the edge, it slows down.An ice skater spins with her arms extended at a particular speed, but when she pulls in her arms, the rate of spin increases - but the angular momentum remains the same. Her hands and arms, pulled in, have a shorter "moment arm", so to keep the angular momentum constant, the speed increases.A star like our Sun spins in about 25 days. Our Sun is too small to go nova, so let's imagine a star twice as massive. If it were to go nova, about half of the mass would be blown off into space, but the remainder would be crushed into a tiny ball perhaps 20 miles in diameter. But that spinning star, with a rotation speed of perhaps 25 or 30 days, would keep a good part of the angular momentum. The star which once spun at a rate of one rotation per 25 days, with a radius of a half-million miles, now has a radius of 10 miles. So to keep the same angular momentum in such a small package, the neutron star remnant would spin much faster; probably several times per SECOND.
What does a planets rotation cause?
This is a very good question that may not have an ultimate answer, but there is an explanation. The reason a planet rotates is due to its origins from the nebula from which it formed. This nebula had to be rotating. You probably have heard about the gyroscope and how it works- conservation of angular momentum. Angular momentum is determined by the rate of rotation and the mass of the object and its distribution as a function of distance from the axis of rotation. This is the principle behind an ice-skater spinning up when the arms are brought close to the body, or slowing down when the arms are extended. Except for dissipation and action of other torques, angular momentum is held constant. Thus the rotation of the gases and dust from which a planet formed causes the planet to keep on rotating, to conserve the initial angular momentum.The planet's rotation is of course changed by events both inside and outside of the planet. For example, it has been recently shown that the use of dams has changed the distribution of stored water on earth at different latitudes, sufficiently to change the length of the day! The difference is small, but has been detectable.But, why is the angular momentum conserved? And why was the nebula rotating if the universe began in a big bang?
Will law of momentum also hold good if momentum is a scalar quantity?
Momentum is never scalar. Are you sure you phrased that right?
What can you write a good sentence with a word angular?
The man had an angular face.......... read this type of stuff in so many novels.
What are the advantages of wheel?
the good things about the wheel consist of transportation, the ability to move large objects, and the invention of the wheel led to the invention of other important inventions such as the gear leading to the invention of automobiles.
What cause planets to orbit the sun?
i know only one and it's a good one, the sun's gravity pulls the planets from flying some where else EDIT: Gravity pulls objects together and angular momentum makes sure planets orbit
Is wheel good invention?
yes, wheel round. wheel good
What causes the Earth to rotate on its axis?
Well, isn't that just a lovely question! The Earth rotates on its axis because of something called angular momentum. It's like a big beautiful dance, with the Earth twirling around as it moves through the endless space, creating day and night for all the creatures to enjoy. How lovely it is to think about the gentle movement of our dear planet!
What is the force that keeps the Earth spinning on its axis?
Well, isn't that just a happy little mystery! The force that keeps our Earth happily twirling around on its axis is called inertia. Just like a pleasant dance partner, it keeps everything moving smoothly along without any fuss.
Has anyone attempted to change the direction of a rocket?
Nasa does it all the time- there are maneuvering jets, steering engines, etc- used for angular corrections ( bear in mind in space there is no atmosphere or wind resistance) Spacecraft- once underway run on momentum a good deal- engines shut down... economical.
Why do neutron star spin so rapidly?
Most stars spin (albeit is very slowly), but when the star starts to shrink it will speed up due to conservation of angular momentum. Moreover because a neutron star is so very heavy it takes a long time for it to slow down (breaking can occur via magnetic fields for example). You can test this principle yourself by sitting into an office chair, spreading your arms, and have someone give you a good whirl. You will find that while spinning you will spin faster if you pull your arms inwards and slower if you put them out again.
