The box in the picture begins motionless, and then both forces are applied at the same time. describe the resulting motion of the box. a) the box will not move. b) the box will move to the left. c) the box will move to the right. d) the box will move to the left and then the right.

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.
