Charge q = 4.00 μc is distributed uniformly over the volume of an insulating sphere that has radius r = 12.0 cm . a small sphere with charge q=+ 2.00 μc and mass 6.00×10−5kg is projected toward the center of the large sphere from an initial large distance. the large sphere is held at a fixed position and the small sphere can be treated as a point charge.

Which statement best describes how private industry decides where to spend the money on research and development

Three different objects, all with different masses, are initially at rest at the bottom of a set of steps. each step is of uniform height . the mass of each object is a multiple of the base mass : object 1 has mass 4..00m , object 2 has mass 1..96m , and object 3 has mass . when the objects are at the bottom of the steps, define the total gravitational potential energy of the three-object system to be zero. if the objects are then relocated as shown, what is the new total potential energy of the system? each answer requires the numerical coefficient to an algebraic expression. each algebraic expression is given using some combination of the variables , , and , where is the acceleration due to gravity. enter only the numerical coefficient. (example: if the answer is 1..23mgd , just enter 1.23)

The material that keeps its new shape after it is stretched is called?
