Homework #3 - Chapter 13 Problem 13.16 3 of 6 11 Review Part A The 75-kg man pushes on the 150-kg crate with a horizontal force F. The coefficients of static and kinetic friction between the crate and the surface are 4,0.3 and p =0.12, and the coefficient of static friction between the man's shoes and the surface is = 0.8. (Figure 1) Select the correct explanation for the fact that the man is able to move the crate. Here...

Chapter 15, Problem 025 GO In the figure, a block weighing 15.4 N which can side without friction on an incline at angle - 30.0, is connected to the top of the incline by a massless spring of stretched length 0.330 m and spring constant 100 N/m. The block is initially at its equilibrium position, (a) How far from the top of the indine is the block's equilibrium point (b) If the block is pulled slightly down the incline and...
Chapter 30, Problem 59 The Bohr model can be applied to singly ionized helium He+ (Z=2). Using the model, consider the series of lines that is produced when the electron makes a transistion from higher energy levels into the nf = 4 level. Some of the lines in the series lie in the visible region of the spectrum (380 nm - 750 nm). What are the (a) minimum value and (b) maximum value of ni for the energy levels from...
I need help with problem #3, please and thank you! Problem #2 (25 points) - The True Hanging String Shape After solving for ye(2) for the scenario in Problem #1, show that the mag- nitude of the tension in the string is given by the expression T(X) = To cosh (Como) where To = Tmin is the minimum tension magnitude in the string which occurs at the bottom point of the string, and then show that the maximum tension magnitude...

Assume that we have three independent observations: where Xi ~ Binomial(n 7,p) for i E { 1.2.3). The value of p E (0, 1) is not known. When we have observations like this from different, independent ran- dom variables, we can find joint probabilities by multiplying together th ndividual probabilities. For example This should remind you the discussion on statistical independence of random variables that can be found in the course book (see page 22) Answer the following questions a...
Chapter 3, Practice Problem 3/125 The 52-in. drum rotates about a horizontal axis with a constant angular velocity 4.7 rad/sec. The small block A has no motion relative to the drum surface as it passes the bottom position = 0. Determine the coefficient of static friction Ys which would result in block slippage at an angular position 0; plot your expression for O Ses 180º. Determine the minimum required coefficient value min which would allow the block to remain fixed...
Chapter 18, Problem 09 Two spherical objects are separated by a distance of 1.55 x 103 m. The objects are initially electrically neutral and are very small compared to the distance between them. Each object acquires the same negative charge due to the addition of electrons. As a result, each object experiences an electrostatic force that has a magnitude of 4.69 10-21 N. How many electrons did it take to produce the charge on one of the objects? Number Units...
