How did scientists first discover what was inside the atom as early as 1900 although powerful microscopes were developed in 1980's?
Rutherford`s Gold foil experiment was probably the most important. A very elegant experiment his research students Geiger and Marsden measured how much deviation an alpha particle moved from a path. A beam of alpha particles, generated by the radioactive decay of radium, was directed normally onto a sheet of very thin gold foil. The gold foil was surrounded by a circular sheet of zinc sulfide (ZnS) which was used as an indicator. The ZnS sheet would light up when hit with alpha particles. Under the prevailing plum pudding model, the alpha particles should all have been deflected by, at most, a few degrees. However they observed that a very small percentage of particles were deflected through angles much larger than 90 degrees. From this observation Rutherford was able to observe and deduct the central structure of the atom:[2]
What is the difference between a cyclotron and a linear particle accelerator?
The primary difference is that the cyclotron provides a "circular" path for the accelerated particles, and the linear accelerator provides a "straight tunnel" as a pathway for the accelerated particles. Both devices accelerate particles, but are suited nicely to be used in tandem The cyclotron is frequently applied as the "initiator" of a particle stream in physics labs with multiple accelerators. The cyclotron feeds the linear accelerator, which then provides a final boost to particles before directing them into a target. And this pair of devices can be set up to feed a larger "ring" accelerator. That is a "simple" three-stage setup for generating and accelerating a string of particles to ramp them up to near light speed. The accelerated particles, with their extreme energies, are then directed into selected targets and the scattering reactions observed.
How does Brownian motion drive diffusion?
Brownian motion is the random motion of particles in a solution resulting from their collisions. Diffusion happens as more and more collisions happen between the particles, they become more interspersed with each other.
What do you do when you have obtained more than the required amount of a solid chemical from a reagent bottle?
You either discard it or put it in a separate bother and label it. You do NOT put it back in the original bottle.
How was the plum pudding model disapproved?
Imagine firing a gun at a plum pudding. You would be extremely surprised if the bullet bounced back. Rutherford directed a beam of alpha particles at gold foil. While the majority went through, a number were detected coming back towards the alpha source. If the protons and electrons in an atom were like a plum pudding no alpha particles would come back. If they were like ball bearings filling the entire atom none would get through However, most went through and a few bounced back, demonstrating that the positive charge was concentrated in a small nucleus. The numbers being deflected back or at various other angles agreed with inverse square repulsion between the alpha particle and the nucleus, showing that the alpha particles never actually hit the nucleus, and thus the maximum size of the nucleus could be determined (about 1/10000 of the diameter of the atom)
How is the Rutherford Experiment Done?
To do the Rutherford Experiment, you have to shoot alpha particles at gold foil to and see where the particles pass through and where they do not. This will give you a general idea of what Rutherford did to discover the nucleus of an atom. However, alpha particles are very hard to come upon, as they are the nucleus of Carbon. Rutherford knew that alpha particles are about 7000 times more massive than electrons and are positively charged and the charge is twice the magnitude of the charge of electrons.when Rutherford directed a beam of alpha particles at a thin gold foil,he found that almost all particles passed through it without deflecting.A very small were deflected at an angle, however, and a few actually bounded back toward the particle source.
Who composed the first Broadway musical written and directed by an African American?
James Hurbet Blake
How can an experiment that dissaproves a hypotosis be useful?
Simple, it saves time and resources that could be directed at another hypothesis.
Who composed the music for the Bollywood film Maachis?
Vishal Bharadwaj composed the music for 'Maachis'.
Who composed the music for Bollywood old film 'Mughal-E-Azam?
The master-music director Naushad composed the music for 'Mughal-E-Azam'.
Who composed the music in Look At Me by Agnes Jaoui?
The music for the 2004 film Look at Me was composed by Philippe Rombi. Anges Jaoui played the character Sylvia Millet in the film and also wrote and directed the film.
If all the vectors in this experiment were directed in the same direction how would you determine the resultant mathematically?
Add the absolute values of each vector.
Who directed the film Sky Pirates?
Sky Pirates was an Australian adventure movie based off the movies Raiders of the Lost Ark, Dirty Harry, Mad Max, and The Philadelphia Experiment directed by Colin Eggleston in 1986.
How did Joseph Priestly relight the candle in his experiment?
He relit the candle with a converging lense or magnifying glass. If the light is directed on the wick of the candle it will relight.
What was the music used in the Zeitgeist movie?
I heard it was all composed by the man behind the movie, Peter Joseph (he directed it, wrote it, pretty much everything).
Who directed The Empire Strikes Back?
Irvin Kershner directed Empire. Lucas did all the rest.
What lights make northern lights?
Northern lights, or auroras, are caused by the collision of energetic charged particles with atoms in the high altitude atmosphere. The charged particles originate in the magnetosphere and solar wind and are directed by the Earth's magnetic field into the atmosphere.
