When a bowling ball hits a bowling pin they both bounce away this is an example of witch type of collision

Which two objects have the greatest gravitational force acting between them

Ahypothetical metal has an orthorhombic unit cell for which the a, b, and c lattice parameters are 0.413 nm, 0.665 nm, and 0.876 nm, respectively. (a) if there are 8 atoms per unit cell and the atomic packing factor is 0.536, determine the atomic radius (in nm). (b) if the density is 3.99 g/cm3, calculate the metal's atomic weight (in g/mol).

In an exothermic chemical reaction the energy gained by the surroundings must be the energy lost by the reaction
