How many muons will it register in one hour

Reference no: EM13536901

The muons created by cosmic rays in the upper atmosphere rain down uniformly on the earth's surface, although some of them decay on the way down, with a half-life of about 1.5?s (measured in their rest frame). A muon detector is carried in a balloon to an altitude of 2000m, and in the course of one hour detects 650 muons traveling at 0.99c towards the earth. If an identical detector remains at sea level, how many muons will it register in one hour? (Remember that after n half-lives, 2^(-n) of the original particles survives).

What is the percent difference : A satellite travels at about 8000m/s. What is the factor γ for this speed? As observed from the ground, by how much would a clock traveling at this speed differ from a ground based clock after one hour (as measured by the latter)? What is the percent..

Calculate the delta V for the arrival at the LaGrange point : I am working on a project where we need to find an optimal transfer for a spacecraft from LEO to the L4 LaGrange point in the Earth-Moon system. In order to calculate the delta V for the arrival at the LaGrange point, we need to know the "veloci..

Spring is initially at rest in its equilibrium position : A mass of 5.0 kg is attached to one end of a spring with a spring constant 80 N/m. The other end is attached to a rigid wall. The spring is initially at rest in its equilibrium position, then a force of 100 N pulls the mass away from the wall, str..
