Consider a damped pendulum consisting of a ball of mass M and radius a suspended by a fine wire of length L below a pivot. The ball is moving through a fluid of viscosity y, and this retards its motion. It is assumed that the ball moves sufficiently slowly that Stokes law applies. Under these conditions, the equation describing the motion of the sphere is given by ML =-Mg sin 0 - 6xual, The initial conditions are 012-= 0, and...

Help Save & A large on-demand, video streaming company is designing a large-scale survey to determine the mean amount of time corporate executives watch on-demand television. A small pilot survey of 10 executives indicated that the mean time per week is 13 hours, with a standard deviation of 2.0 hours. The estimate of the mean viewing time should be within one-quarter hour. The 95% level of confidence is to be used. (Use z Distribution Table.) How many executives should be...

I need help with Part B. I got Part A wrong Part A The activation energy of a certain reaction is 41.6 kJ/mol . At 20 ∘C , the rate constant is 0.0150s−1. At what temperature in degrees Celsius would this reaction go twice as fast? ANSWER IS T2= 32 Part B Given that the initial rate constant is 0.0150s−1 at an initial temperature of 20∘C , what would the rate constant be at a temperature of 120.∘C for the same...

[2] Your answer is partially correct. Try again. The length of a simple pendulum is 0.80 m and the mass of the particle (the "bob") at the end of the cable is 0.28 kg. The pendulum is pulled away from its equilibrium position by an angle of 9.5° and released from rest. Assume that friction can be neglected and that the resulting oscillatory motion is simple...

Learning Goal: To analyze an RC circuit to determine the initial voltage across a capacitor, the time constant, and the expression for the natural response of the capacitor voltage, and then to find other circuit quantities such as current,voltage, power, or energy. The natural response of an RC circuit is the response of the capacitor voltage to the sudden removal of a DC source. When this occurs, the capacitor releases its stored energy Figure < 10121〉 t 0 V.

Consider a father pushing a child on a playground merry-go-round. The system has a moment of inertia of 84.4 kg · m2. The father exerts a force on the merry-go-round perpendicular to its 1.50 m radius to achieve a torque of 375 N · m. (a) Calculate the rotational kinetic energy (in J) in the merry-go-round plus child when they have an angular velocity of 10.0 rpm. ___J (b) Using energy considerations, find the number of revolutions the father will...

The Australian Government’s Energy Efficiency Opportunities
program encourages large energy using businesses to improve their
energy efficiency. It does this by requiring businesses to
identify, evaluate and report publicly on cost effective energy
savings opportunities. As part of the process of identifying
factors impacting on electricity consumption, a large super market
chain took a sample of 30 stores and investigated the relationship
between electricity consumption and store size. Consider the simple
