When you drop a ball it accelerates downward at 9.8 m/s2. if you instead throw it downward, then its acceleration immediately after leaving your hand, assuming no air resistance, is
a. 9.8 m/s2.
b. more than 9.8 m/s2.
c. less than 9.8 m/s2.
d. cannot say, unless the speed of throw is given.

What is binding energy and separation energy

At time t=0, a particle is located at the point (3,6,9). it travels in a straight line to the point (5,2,7), has speed 8 at (3,6,9) and constant acceleration 2i−4j−2k. find an equation for the position vector of the particle.

High schoolphysics 5+3 pts a neon light consists of a glass tube with metal wires at each end. when connected to a high-voltage source, the gas glows. if a fly lands on the glass tube, what will most likely happen? a) the fly will not feel a shock because the glass conducts any free electrons back into the gas. b) electrons will flow directly from the metal wires along the glass and shock the fly. c) the fly will not feel a shock because the glass insulates it from the electrons in the gas and the metal. d) electrons that are moving through the gas will be conducted through the glass and shock the fly.
