Which of the following does NOT happen when we smell an aroma? O The senses of smell and taste work together. O A chemical in the air triggers a response in a receptor in the nose. O The receptors in the nose identify the aroma before sending nerve impulses to the brain. Nerve impulses travel to the brain and are interpreted as a smell.​

you need to have a picture of the atom that way we can answer it

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.
