1. A) Part of the wave might penetrate it or it might not. This would be random and would depend on the energy of the electron attempting to penetrate.
B) The pattern that initially seemed random would begin to acquire uniformity. Half of the electrons would transmit and half would reflect and go back. Each of the electrons that transmitted would carry its complete charge and mass.
C) One cannot say where the electron really is, whether a given electron will transmit or reflect. It is only possible to state the probability of electrons actions. For example, one may say that the probability is one in five that the electron will transmit and four out of five that it will be reflected back.
D) Some physicists find the result difficult to accept because they perceive it as what Einstein called “God playing dice with the universe”. The unpredictability inherent with this result and the fact that it seems to contradict both Newtonian physics as well as reality, make it a less than ideal paradigm for many physicists.
E) David Hume would have vehemently objected to my answer on part C). Hume’s word view was largely based on the belief that, to understand events in the universe, we must look to their cause. This casual link is, therefore, disrupted under the conditions witnessed in the aforementioned experiment, as we can see a cause but the result side of the chain is unknown.
2. A) Some Greek scientists based their opinion that the space between the earth and the planets and
b. What phenomena must take place for the small postsynaptic potentials to reach threshold and produce action potentials?
Please choose from one (1) of the scenarios below. Note: The scenario that you choose in this assignment will be the one (1) with which you continue for Assignment 2.
One of J.J. Thomson's most significant contributions to science, and thus to the study of atomic theory, was his discovery of the electron. Before the discovery of the electron, the atom was already associated with having electric charges-both positive and negative-but the idea of an electron existing as its own particle was unheard of. It was in 1897 when Thomson first conducted the beginning of his now famous experiment, in which he used a cathode ray tube to aid in his findings. A cathode ray tube, is a vacuum tube in which cathode rays, negatively charged particles, are produced at the cathode and travel through the vacuum, which is created when gas is extracted from the tube. J.J. Thomson discovered that in order to determine
A sodium ion (Na+) occurs when a sodium atom loses an electron and gains a positive charge
K. Paraphrase the three potential fates of the excited electron produced when a photon meets a chlorophyll molecule
5. ___G__ You go to a lecture and the topic seems to focus on blue-yellow and red-green perception of color. The lecture is likely discussing ______________.
For problems 12 to 14, do the following: (a) Make a scatter diagram of the
3. Electrons are small and are negatively charged (-) with a mass of almost 0 amu..
10) If the second positive charge were moved away from the first Positive charge, would this involve positive or negative work.
9) As you sample the electric field further and further from a charged object, you find that the field strength weakens. Do you think the E field vs. distance relation is an inverse
The conducting species at equivalence point would be the Sodium as it has the most free-range electrons and dissociates readily in solutions.4
In this paper I discuss both Hume’s and Anscombe’s view on causation. I begin with Hume and his regularity theory; then I move onto Anscombe where I provide a rebuttal of Hume’s regularity theory, and later I explain how Hume would respond to Anscombe’s objection to Hume’s regularity theory.
2) Which of the following models determines the path through the network that connects all the points?
Following questions given below contains a statement and two assumptions. Find which of the assumptions implied by the statement. Choose any of the following options.
(Frova 41) Galileo’s confirmation of Copernican’s heliocentric theory explained through logical arguments and mathematical laws clearly the answers to these difficulties.
