Is this covalent structure of oxygen (O2) drawn correctly? Explain your why or why not.

the answer to your question is c.

if you read the house of usher you should know that the house was haunted

1.solid

2.carbon dioxide

3.helium

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.
