Abicycle weighs 32.5 pounds. the box for it weighs 7.8 pounds. what is the total shipping weight for the bicycle and its box?

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.

it is a solid

explanation:

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.
