A point charge Q resides at the origin. A particle of mass 0.001 kg carries a charge of 3 µC. The particle is released from rest at x = 2 m, and its kinetic energy as it passes x = 0.5 m is 0.36 J. Find the charge Q. The Coulomb constant is 8.98755 × 109 N · m 2 /C 2 . Answer in units of µC.

Excuse ! extra points plus ! super desperate ! the position of an object does not move relative to a reference point. relative to the reference point the object _. a.) is not moving. b.) is moving.

Newtons view of arrangement of the universe

Newton's law of cooling states that the rate of change in the temperature t(t) of a body is proportional to the difference between the temperature of the medium m(t) and the temperature of the body. that is, startfraction dt over dt endfraction equals upper k left bracket upper m left parenthesis t right parenthesis minus upper t left parenthesis t right parenthesis right bracket , where k is a constant. let kequals0.04 left parenthesis min right parenthesis superscript negative 1 and the temperature of the medium be constant, m(t) font size decreased by 3 equivalent font size decreased by 3 294 kelvins. if the body is initially at 369 kelvins, use euler's method with hequals0.1 min to approximate the temperature of the body after (a) 30 minutes and (b) 60 minutes.
