can use heating oil futures to hedge its exposure to diesel fuel prices. Which futures position should J & L take? Explain. J&L Railroad should take a long position. They need to purchase diesel fuel in the future‚ they don’t produce diesel fuel‚ so they would want to take a future to be able to lock in the price of diesel fuel for future purchases. 2. What problems could the use of heating oil futures for hedging create for J&L? Note: I assume this question is asking about heating oil specifically

Electrical Q&A Part-3 Questions and Answers related to Transformer: 1. What is a transformer and how does it work? * A transformer is an electrical apparatus designed to convert alternating current from one voltage to another. It can be designed to “step up” or “step down” voltages and works on the magnetic induction principle. * A transformer has no moving parts and is a completely static solid state device‚ which insures‚ under normal operating conditions‚ a long and trouble-free

warming is a natural cause. The Earth was heating long before humans were emitting large amounts of greenhouse gases and even before humans were on planet Earth. Since humans were not alive during the period after the ice age (known as the post-ice age era)‚ then the heating of the Earth to melt the ice does not put humans at fault. Global warming is naturally caused by natural emission of greenhouse gases‚ Earth’s heating and cooling system‚ and other planets heating without human life on them. The Earth

Properties of paper Physical Properties Basis Weight or Grammage The basis weight‚ substance or grammage is obviously most fundamental property of paper and paperboard. The Basis weight of paper is the weight per unit area. This can be expressed as the weight in grams per square meter (GSM or g/M2)‚ pounds per 1000 sq. ft. or weight in Kgs or pounds per ream (500 sheets) of a specific size. Paper is sold by weight but the buyer is interested in area of paper. The basis weight is what

calculating the water of crystallization for the unknown hydrate salt. A hydrate salt is composed of anions (-) and cations (+) surrounded by a fixed number of water molecules‚ called water of crystallization. The hydrate decomposes upon heating and produces an anhydrous salt. After finding the formula mass of the hydrate by adding the amu ‚ we can calculate the percent of water in the hydrated salt by comparing the mass of the water of crystallization to the mass of the hydrate salt.
