A men’s world record for the shot put is 23.13 m. If the shot was launched at 1.82 m abovethe ground at an initial angle of 42◦ ,
(a) (3 points) What was the speed of the shot?
(b) (3 points) What was it’s maximum height above the ground?
(c) (3 1/4 points) How much time was the shot in flight?
(d) (3 1/4 points) What was its velocity (magnitude and direction) just before it struck the
ground

Which subatomic particle has a negative charge

Carbon 14 is a naturally occurring stable

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
