Which helps identify the law of gravity as a law? In his experiments at the Tower of Pisa, Galileo found that gravity accelerates all objects at the same rate.
It states that gravity is a force of attraction that exists between any two objects in the universe.
It is based on scientific observations made by several different scientists over hundredths of years.
It explains how the masses of two objects and the distance between them determine the exact amount of the fom

answer; 4 electrons;

the answer your looking for is c).

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.
