A turntable has a moment of inertia of 2.5 x 10-2 kg m2 and spins freely on a frictionless bearing at 33.3 rpm. A 0.5 kg ball of putty is dropped vertically on the turntable and sticks at a point 0.20 m from the center. What is the new rate of rotation of the system?
Find what must be the resolving power of a grating allowing a spectral line at 601.10 nm to be distinguished from another line differing by 0.38 nm
A uniform road of cross section area A and length L has material properties E (Young's modulus) and p (mass per unit length). The rod is anchored at one end but has a forcing function Fosin wt at the other end. The governing partial differential e..
Suppose an electron starting from rest is accelerated in a uniform electric field directed horizontally and having a magnitude of 3000N/C . The electric field covers a region of space 12.5cm wide.
The proper mean lifetime of subnuclear particles called pions is 2.6 × 10 ^-8 seconds. A beam of pions has a speed of 0.72 c in a laboratory. The speed of light is 2.998 × 10 ^8 m/s. In the reference frame of the pion, how far does the pion travel ..
A rod of proper length L moves past you a speed v. You reach out and grab the back end of the rod, bringing that point instantly to rest in your frame of reference.
