Q-1A) Identify if TRUE or FALSE, give an explanation for the FALSE ones only). a. If a homogenous piece of rock is cut into two pieces, then each one will have the same formation factor. h Micro-resistivity log can be used in oil-based mud and water-based mud systems. L. In a water bearing formation, Ro is equal to the Rt. d. A high GR value always indicates the presence of shale. e One of the most important application of the SP log is to measure the formation permeability. L Caliper log shows a smaller reading that the bit size for evaporite (Salt) layers. g. If the micro-Inverse and micro-Normal logs exhibit positive separation, the permeability of the formation is small. b. A reverse/positive SP deflection occurs when Rmf< Rw. i Water Saturation is defined by the ratio of water volume to the bulk volume of a rock. i The higher formation porosity, the larger invasion diameter. k. Induction log measures the formation resistivity. L Well-logging measurements are recorded while puling…

TRUE OR FALSE 1.) In rheology, food materials of higher viscosity have higher resistance to flow. 2.) Specific heat is the amount of heat needed to raise the temperature of a unit mass of an object one degree higher without change of phase 3.) Surface area, is related to size but also depends on particle shape. 4.) Size can be correlated with weight given that the material has more or less uniform composition. 5.) Latent heat of fusion is the amount of heat that must be removed to convert water to ice and is also the same as the amount of heat added to convert ice to water.

The company has three options. Supplier A sells the silicon wafers for $2.50 per wafer, independently of the number of wafers ordered. Supplier B sells the wafers for $2.40 each but does not consider an order for less than 2,000 wafers. Supplier C sells the wafers for $2.30 each but does not accept an order for less than 3,000 wafers. Assume an order setup cost of $100 and an annual requirement of 20,000 wafers. Assume a 20% annual interest rate for holding cost calculations. a. Which supplier should be chosen to minimize the total annual cost for the wafers, and what is the optimal order quantity? b. If the replenishment lead time for wafers…

TRUE OR FALSE Directions: Choose true is the statement is correct, otherwise choose false. 1. Literature is not related to a certain region’s culture, tradition, history and people. 2. All written, oral, and multimedia forms of work are considered literature. 3. Poetry commonly utilizes rhymes and figures of speech while prose uses formal sentence structures. 4. Drama is delivered on a theatrical stage with actors and actresses. 5. Fictional works have the same elements of non-fictional works. 6. Facts, information, and statistics are focused on non-fictional works. 7. Human history and advancements were possible without the role literature. 8. The standard of universality conveys that literature must be perpetual and timely. It is forever relevant and it appeals to one and all, anytime, and anywhere. 9. Intellectual beauty expresses that a literary piece must stimulate thought about life and human nature, while suggestiveness pertains to how it evokes emotion of the reader. 10. All…
