At t = 0 a block with mass M = 5 kg moves with a velocity v = 2 m/s at position x o = -.33 m from the equilibrium position of the spring. The block is attached to a massless spring of spring constant k = 61.2 N/m and sl ...
A juniper-wood plank measuring 0.32 ft by 1 ft by 12 ft is totally submerged in water. (a) What is its weight? (b) What is the buoyant force acting on it? (c) What is the size and the direction of the net force on it?
What is the error in the Boltzmann approximation if the crystal size is not infinite but contains 10 2 , 10 3 , 10 4 , 10 5 , 10 6 , 10 9 atoms? This is a very real situation in submicron transistors In which an active ...
In a time of t seconds, a particle moves a distance of s meters from its starting point, where s = 4t 3 . (a) Find the average velocity between t = 0 and t = h if: (i) h = 0.1, (ii) h = 0.01, (iii) h = 0.001. (b) Use you ...
Suppose your bathroom scale reads your mass as 82 kg, with an 8% uncertainty. What is the uncertainty in your mass? (Note that uncertainties should be reported to one significant figure.)
Two flywheels, one with moment of inertial 240kgm^2 and one with moment of inertial 150kgm^2 turn on the same shaft. The First wheel is fixed on the shaft, the second one is connected by a clutch, so that it can be made ...
1. The two lowest-energy wave functions of the electron bund to the two protons are symmetric and antisymmetric. Sketch and explain why one has a lower energy while the other has a higher energy. 2. An electron is inject ...
At what electron and hole concentrations is the resistivity of a semiconductor a maximum? Give numerical values for Si at 300K. Note in practice one cannot refine Si to such a purity, however, this can occur in a p/n jun ...
The 2010 Census3 determined the population of the US was 308.75 million on April 1, 2010. If the population was increasing exponentially at a rate of 2.85 million per year on that date, find a formula for the population ...
The preceding exercise (parts b and c) involved a utility function based on regret. If one married the tenth most desirable candidate, the utility function asserts that one would feel regret for having not chosen the mos ...
