Transport Phenomenon (Electrical and Thermal) in two allotropic forms of Carbon (Diamond and Graphite) Graphite and Diamond both are formed from carbon (two allotropic forms of carbon). Though they have similar constituent element‚ they differ a lot in their properties. Diamond is a good thermal conductor but a bad electrical conductor‚ while graphite is a bad thermal conductor but a good electrical conductor. This is one example of their property difference.

If it is non-linear one then we convert it into log-linear to estimate the equation. Among the scatter of points in plane X-Y‚ we try to fit in the best line that can estimate the relationship. Here Y is the dependent variable and X is the independent variable. Let us take the example given in Salvatore. Let demand be the function of advertisement expenditure by the particular firm. Then the scatter diagram will show as the ad. Exp. Increases the sales volume will rise. In order to estimate the

CASE STUDY: 1 The bulbs manufactured by a company gave a mean life of 3000 hours with standard deviation of 400 hours. If a bulb is selected at random‚ what is the probability it will have a mean life less than 2000 hours? Question: 1) Calculate the probability. Probability is the measure of how an event is likely to occur out of the number of possible outcomes. Calculating probabilities allows you to use logic and reason even with some degree of uncertainty. Find out how you can do the math
