A centrifuge is rotating at 10,000 revolutions/minute. It is brought to rest in 4.00 seconds under a constant acceleration.
(a) Determine the initial angular velocity of the centrifuge in rad/sec.
(b) Determine the angular acceleration ?.
(c) If the radius of the centrifuge is 8cm, determine the distance that a point on the rim travels during the deceleration time.
Consider a spherical Gaussian surface and three charges:q1=1.76microC, q2= -2.50microC, and q3=3.69microC. Find the electric flux through the Gaussian surface
Treat a Boron atom as 5 protons at the origin, 2 electrons spread uniformly on a shell (radius 13.2[pm] centered on the origin) , 2 more electrons spread on a shell (radius 105.8[pm] centered on the origin), and its outer electron at x= 211.6 pm.
