The Maxwell-Boltzmann probability density
where m (kg) is the mass of each molecule, v (m/s) is the speed, T(K) is the temperature, and k = 1.38×10-23J/K is Boltzmann’s constant. The most probable speed vpcorresponds to the maximum value of f(v) and can be determined from

In the cartesian coordinate system, the coordinate variables x, y, and z are already length dimensions, so the scaling factors to convert them to length are hx=1, hy=1, and hz=1. In the cylindrical coordinate system, the scaling factors to convert the rho and z into length , are hrho=1 and hz=1. A) what is the hpi that changes coordinate pi into the length? B) in terms of spherical coordinates, what is the hr, htheta , hpi that changes ( r, theta, pi ) of spherical coordinate into the length?arrow_forward

Let us say that this motor in particular has a shaft. This shaft that the motor is composed of is then turning at an anguler speed at the time when t is equal to 0. a = A + Bt after the times t= 0, we have In this case, A & B contain apprOpriate units. (rad/s) α (rad/s^2) :) WE NEED TO GET: a. We need to figure out what would be the angulor speed of this shaft that we are talking about at any t at all. b. We need to figure out what would be the alteration in angulor position of this shaft we are talking about that is relative to its t value for any t at all. c. let us imagine if the shaft that we are talking about has a radius (r of course), we need to figure out what will be the distances will a point on the edge of the shaft have traveler from t=0 to t.
