Which statement is a correct statement of Newton's second law? A. When an object experiences a net force, it will accelerate at a rate determined by its mass.

B. Every action has an equal and opposite reaction.

C. An object in motion stays in motion, and an object at rest stays at rest unless acted upon by a net force.

D. Every mass in the universe is attracted to every other mass in the universe.

the millers tale is the answer.

answer: semi-infinite solid initially at a uniform temperature of 400 ◦c is cooled at its surface by convection. the cooling fluid at a constant temperature of 200 ◦c has a convective coefficient (ha) of 250 w/m2.k. the physical properties of the solid: k = 20 w/m.k and α = 4 * 10-5  m2/s. using δx = 0.04 m and δt = 10 s. write the finite difference equations describing the transient heat transfer of the first five δx and the temperature profile after 30 s.
