The Nutrition Facts label for 1 slice of wheat breThe Nutrition Facts label for 1 slice of wheat bread gives the percent daily value of various nutrients based on a 2,000-kcal diet. Based on the percent daily values for the nutrients, calculate how many grams of each nutrient are suggested daily, for a 2,000-kcal diet.

the answer is a for sure mark brainliest i had got this right on usatestprep

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.
