With this information how do I go about graphing a linear graph to prove if the experiment shows a linear relationship? Also what are some good started claims for a CER (claim, reasoning, and evidence)? I am stuck on doing the graph and coming up with a claim.Thank you!
For seven identical, non-interacting harmonic oscillator molecules (energy levels given by the harmonic oscillator model), and given the macroscopic constraints (a) Etot = (4+7/2)hw and (b) Etot = (7+7/2)hw; work out the probabilities of observing a molecule with energy Eusing the fundamental postulate of statistical mechanics. Fit an exponential decay to these probabilities (using Excel or some other program) and find the relationship qualitatively)between Etot and the temperature T? Discuss in relation to the Boltzmann factor.
Block 1, of mass m_1 = 0.700 kg, is connected over an ideal (massless and frictionless) pulley to block 2, of mass m_2, as shown. Assume that the blocks accelerate as shown with an acceleration of magnitude a = 0.400 m/s^2 and that the coefficient of kinetic friction between block 2 and the plane is mu = 0.400. Find the mass of block 2, m_2, when theta = 30.0^circ

1) Fix a clothespin (can also use something similar like the clip used to re-close an open bag of chips) to a baby food jar (or something similar – big enough to support the clothespin) with two rubber bands so the jaws point up.
2) Wedge the clothespin wide open with another half clothespin tied to a trip thread.
3) Put this next to a baby food jar lid (or next to a plastic lid from a 64 oz. juice bottle, with a quarter taped to the lid) in an open area on the floor. Pull the thread with a quick flick of your wrist. Use a meter stick to measure the distance the objects travel. In the Data Table below, record your data on distance, time, and the mass of the lid; then do the calculations.
Describe what happens. Interpret your observations in terms of Newton’s third law.
A m = 31.9 kg object is released from rest at a distance h = 0.636658 R above the Earth’s surface. The acceleration of gravity is 9.8 m/s 2 . For the Earth, RE = 6.38 × 106 m, M = 5.98 × 1024 kg. The gravitational acceleration at the surface of the earth is g = 9.8 m/s 2 . Find the speed of the object when it strikes the Earth’s surface. Neglect any atmospheric friction. Caution: You must take into account that the gravitational acceleration depends on distance between the object and the center of the earth. Answer in units of m/s.
