Block 1 is attached to a spring and oscillates on a horizontal frictionless tabletop. When block 1 is at a point of maximum displacement, block 2 is brought from above and placed directly on top of block 1 without interrupting the oscillation. The two blocks stick together. How do the period of oscillation and the maximum kinetic energy with both blocks compare to those of block 1 alone? (Hint: assume no work is done on the system when the second block is introduced.)

Iflow from a warmer object to a cooler object until both objects are the same temperature what am i?

To understand the electric potential and electric field of a point charge in three dimensions consider a positive point charge q, located at the origin of three-dimensional space. throughout this problem, use k in place of 14? ? 0. part adue to symmetry, the electric field of a point charge at the origin must point from the origin.answer in one word.part bfind e(r), the magnitude of the electric field at distance r from the point charge q.express your answer in terms of r, k, and q. part cfind v(r), the electric potential at distance rfrom the point charge q.express your answer in terms of r, k, and q part dwhich of the following is the correct relationship between the magnitude of a radial electric field and its associated electric potential ? more than one answer may be correct for the particular case of a point charge at the origin, but you should choose the correct general relationship. a)e(r)=dv(r)drb)e(r)=v(r)rc)e(r)=? dv(r)drd)e(r)=? v(r)r
