The intensity I of a sound wave is measured in watts per metre squared ( ). The lowest intensity that the average human ear can detect‚ i.e. the threshold of hearing‚ is denoted by ‚ where . The loudness of sound‚ i.e. its intensity level ‚ is measured in decibels (dB)‚ where . From this function a specific relationship between and can be drawn that holds true for any increase in intensity. By knowing the value of beta ( )‚ the value of can be found via manipulation of the logarithmic

Lesson 9: d-t & v-t Graphs Graphing the motion of objects gives us a way to interpret the motion that would otherwise be difficult. ● Graphs will also allow you to show a large amount of information in a compact way. Essentially you need to be able to sketch and interpret two main kinds of graphs in kinematics: 1. Displacement – Time Graphs ● Sometimes called d-t graphs‚ or position – time graphs. 2. Velocity – Time Graphs ● Sometimes called v-t graphs. Displacement - Time (d-t) Graphs

Evaluate between Japanese term loan and Goldman’s proposal There are many alternatives which can hedge this exposure; however‚ Mr. Anderson decided to rule out some of them for the reasons as follows: * FX option * Ruling out due to non-exist of long-term maturities * Long-dated FX forward * Disney consider it as a part of total exposure * Currency swap * Existing Disney’s Eurodollar is short-term; attractive rates for short-term is rare in Mr. Anderson’s perspective

1. A company enters into a short futures contract to sell $5000. The current future price is 250 cents per pound. The initial margin is $3000 and the maintenance margin is $2000. What price change would lead to a margin call? Under what circumstances $1500 could be withdrawn from the margin account? 2. Stock is expected to pay a dividend of Tk 10 per share in 2 months and again in 5 months. The stock price is Tk 500 and risk free rate of interest is 8% p.a. with continuously compounded for all

Many pundits consider Financial Crisis as the cyclic event that recurs after passage of certain interval in Economic Lifecycle‚ but they should consider it only wrongs by the side of human intellectuals.
