How Can Humans Help? 1 Design a persuasive flyer that encourages people to help prevent wildfires from starting. Be sure to include what can cause them, how to prevent them, and why they are so dangerous. Use the space below to design your flyer​

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.

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.
