Question 1 (a) Estimate the volume (in m3) and density (in kg m3) of a C nucleus. State your assumptions and comment on the value obtained Write down a relationship between a particle's energy, mass and momentum using relativistic (b) kinematics. The SuperKEKB b-factory will collide electrons with energy 7 GeV and positrons with energy 4 GeV in order to produce b-hadron pairs. Write down the four vectors of the electron and positron Hence work out the centre-of-mass energy of...
Please answer all parts of the question and make writing legible f(x)-sin(x) a. Use differentials and linearization to estimate the value sin(1.02) b. Sketch the graph that demonstrates the concepts of linearization as it pertains to this problem given c. Based on the graph sketched not what is on the calculator, is your estimate an overestimate or underestimate? Explain the reasoning referring to the sketch in part b. Verify your conclusion by using the calculator to find the actual value...
in order to compare the means of two populations, independent random samples of 400 observations are selected from each population with the results: sample 1: x1= 5275 and s1= 150 sample 2: x2= 5240 and s2 = 200 a. use a 95% confidence interval to estimate the difference between the population means (m1-m2) interpret the difference. b. test the null hypothesis (m1-m2 = 0) versus the alternative (m1-m2 isn't = to 0). give the p-value of the test and interpret...

Please show all work for Number 2. Thank you. ) Solve the nonhomogeneous system: (t) 5 -2 x(sinh(t) 7.jk(t)-| cosh(t)) 20 An interesting application that leads to a system of differential equations is the study of an arms race. The presentation given here is often called the Richardson model, since it was first proposed by the English metcorologist L.E Richardson. We wish to consider the problem of two countries with expenditures for armaments, x and y, measured in billions of...
Can you please solve it in Excel? Also i cannot understand how i calculate all averages, s. deviations and result with just one function for every compound.(The problem that i cannot understood is explained in p.s. section) 3. Fluorescence values of 4 different compounds (A, B, C and D) were measured (each in triplicate) and the results of each compound were given in the table. Compound Measurement Result Mean Standard Deviation Result (%) No. 100 | 1. 2. 3. 1....

1. Table of descriptive statistical measures (arithmetic mean, standard deviation, smallest value and largest value) for the variables in the model with a detailed discussion of the table2. The equation is in the community form of the model you reached, then display the results of the estimated equation from the Gretl program with errors. Standard normal as well again with proper standard errors.3. Discuss and explain the results of the estimated model and then the number of reasons why the...
