What is the unit for mu? Does it matter if we use kg for mass or grams when we calculate mu?
Homework Answers
mu (coefficient of friction) is a unitless quantity.
It does not matter if we use kg for mass or grams when we calculate mu because mu is unitless quantity.

A cosmic ray muon with mass mu = 1.88 x 10-28 kg impacting the Earth's atmosphere slows down in proportion to the amount of matter it passes through. One such particle, initially traveling at 2.50 x 106 m/s in a straight line, decreases in speed to 1.44 x 106 m/s over a distance of 1.28 km. (a) What is the magnitude of the force experienced by the muon? 5.025 Your response differs significantly from the correct answer. Rework your solution...

Answer the questions below by assuming the spherical mass distribution of dark matter in our Galaxy, where the Galactic radius is 100,000 light years, the distance of the solar system from the center is 27,000 light years, and the constant orbital speed of stars is 220 km s1. Use the gravitational constant 6.674 x 10-11 N m2 kg2, light year 9.46 x 1015 m, and solar mass 2.0 x 1030 kg. 1. show the mass of dark matter inside radius...

Galaxies contain both stars and dark matter. The mass M of a galaxy that is located within a certain star's orbit is given by where v is the velocity of the star, r is the distance from the galaxy's center to the star, and G is Newton's gravitational constant, 6.673 x 10- N m/kg Stars near the edge of a particular galaxy have velocities of 259 km/s. The radius of the galaxy is 53 kpc. How much mass is in...

One particle has a mass of 4.87 times 10^-3 kg and a charge of +7.68 mu C. A second particle has a mass 7.72 times 10^-3 kg and the same charge. The two particles are initially held in place and then released. The particles fly apart, and when the separation between them is 0.133 m, the speed of the 4.87 times 10^-3 kg particle is 161 m/s. Find the initial separation between the particles. Number Units

A particle of mass 6.5 times 10^-8 kg and charge +9.7 mu C is travelling due east. It enters perpendicularly a magnetic field whose magnitude is 4.4 T. After entering the field, the particle completes one-half of a circle and exits the travelling due west. How much time does the particle spend in the magnetic field? Number Units the tolerance is +/-5%
