What happens to a positively-charged alpha particles that comes the positively-charged nucleus?
It will repel
What is the velocity of an electron with a mass of 9.11 x 10-31 kg at a position with an uncertainty of 5x10-10 m?
The Heisenberg Uncertainty Principle states that the product of the uncertainty in position and momentum is at least equal to h/4*pi. The momentum of the electron is equal to its mass multiplied by its velocity. Using the uncertainty principle, you can calculate an approximate lower limit for the velocity.
What is a single journey along an orbital path?
A single journey along an orbital path refers to one complete revolution of an object around a central body, such as a planet or star. This journey follows a specific trajectory determined by the object's velocity and gravitational forces.
Why cant you determine the exact location of an electron in an atom?
Because the electrons are in constant motion(momentum), so to find their exact location one must find this location plus momentum at the same time. It is thought to be impossible to find the exact location and momentum simultaniously, because, to find location you must stop the particle, and to find momentum the particle must be moving.
How does a laser particle counter work?
Particle characterization plays key role in powder industry especially in particle size analysis. The latest technology of particle characterization is to use a particle size analyzer (also named Particle Size Analyser) running particle size analysis by laser diffraction technology. Laser diffraction is a phenomenon when a light illuminates particles inside an analyzer (analyser) the light is diffracted by the particles in different sizes. The scattered patterns of particle size go through analysis by an analyzer (analyser) and the Particle Size Analysis software gives results of particle size distribution. Particle Characterization by Laser Diffraction is of great significance for material characterization.AS-2011 Laser Particle Size Analyzer (also named Laser Particle Size Analyser) works with principle of Mie Scattering to precisely determine the particle size distribution from 0.1 to 500 micrometer. This equipment has a few advantages all its own. Robust laser diode and innovative photocells optimize the precision of static light scattering and give AS-2011 a longer operational lifetime. Patented optical bench uproots light path deviation, one of the major technical problems in the industry of particle size analysis. User-friendly program and advanced algorism bring accuracy and repeatability qualification to International Norm ISO13320-1 Particle Size Analysis - Laser Diffraction Methods. AS-2011 has become the most reliable and cost-effective LPSA and being widely used in Particle Characterization.By AimSizerhttp://www.aimsizer.com
Why is velocity tangential to the path of a body?
Velocity is a vector; having direction. So, when changing direction constatly to have velocity a tangent can be drawn to the constantly changing path of the object having velocity.
Streamline and pathline?
Streamline: the flow in which velocity is always tangent to the path. Pathline: the path followed by the fluid particle is called pathline.
Is it true or false that For a particle in uniform circular motion the instantaneous-acceleration vector is directed radially outward?
True. In uniform circular motion, the particle's velocity is tangential to the circular path, and the acceleration is directed radially inward, towards the center of the circular path. This centripetal acceleration causes the change in direction of the particle's velocity, but the magnitude of the velocity remains constant.
What force is streamline?
Streamline refers to a path traced by a fluid particle moving in a steady flow without any turbulence. It represents a line that is tangent to the velocity vector of the flow at every point. By following these streamlines, engineers can analyze the behavior of fluids in channels or around objects.
What is meant by rectangular triangle componenets of a vector?
If you plotted the original path and velocity, and the path and velocity of the 'impacting' force, then the third leg of the triangle will be the resultant path and velocity.
If the acceleration of a particle is constant in magnitude but not in direction what type of path the particle follow?
If the acceleration of a particle is constant in magnitude but not in direction, the particle will follow a curved path. The changing direction of the acceleration will cause the particle to continually change its velocity vector, resulting in curved motion.
What determines the nature of path followed by the particle?
Velocity
What is areal velocity?
The areal velocity of a particle is the rate at which area is swept out as the particle travels along a curve. The area is swept out by a vector (starting at the origin.)In words:Imagine an empty space with a single point in it. That point doesn't move; it represents the the origin. Now image a particle flying around in that space. An arrow always points from the origin to that particle (and touches the particle). As the particle moves, that arrow moves, possibly getting longer or shorter depending on where the particle is. Instead of just moving though, it creates a "path" of area. Everywhere that arrow touches in the space, it "paints" that space, so as it moves, more and more space gets "painted". This "painted space" is the area. The rate at which the amount of this "painted space" changes is the areal velocity of that particle.As equations:dA/dt=r x v/2dA/dt=L/(2m)Notice that the areal velocity is a vector.
What determines the nature of the path followed by the particle?
The nature of the path followed by a particle is determined primarily by the forces acting on it. Forces such as gravity, electromagnetic force, or friction influence the trajectory of the particle. Additionally, initial conditions such as velocity and position also play a role in determining the path followed by a particle.
Why acceleration is tangent to the path?
Acceleration is tangent to the path because it is a measure of the rate of change of velocity. By being tangent to the path, acceleration describes how the direction or speed of an object is changing as it moves along a curved path. The tangential component of acceleration is responsible for changes in speed, while the normal component of acceleration is responsible for changes in direction.
What is the flight path?
HELLO, im a bus driver and i can say that the (FPA )flight path angle is the angle Between the local horizontal and the local velocity vector , One can also support that is the angle between the local velocity vector and The torque vector, torque being opposite to drag, merci
Why the velocity and acceleration of body moving with uniform speed in circular path will be mutually perpendicular?
The velocity of an object moving in a circular path is always tangent to the circle at that point. Meanwhile, the acceleration of the object is directed towards the center of the circle, called centripetal acceleration. Since the velocity is tangent to the circle and the acceleration is pointing towards the center, they will be mutually perpendicular.
