A thin rod (length is 1.50 m) is oriented vertically, with itsbottom end attactched to the floor by means of a frictionlesshinge. The mass may be ignored, compared to the mass of theobject fixed to the top of the rod. the rod, starting from rest,tips over and rotates downward.
(a) What is the angular velocity just before it strikes the floor?
(b) What isthe magnitude of the angular acceleration of the rod just before it strikes?
A pipe is open at both ends. Its length is 22.81 cm. If I excite standing waves in the pipe by blowing air over one of its ends, Find the distance between the antinodes at the two ends of the pipe
Some sharks respond to very weak electric fields, as weak as 1.0 µV/m. To grasp how weak this field is, how far apart would the plates have to be
