Self-insurance is being considered for one portion of a chemical company. The fixed-capital investment involved is $50,000, and insurance costs for complete protection would amount to $400 per year. If self-insurance is used, a reserve fund will be set up under the company's jurisdiction, and annual insurance premiums of $300 will be deposited in this fund under an ordinary annuity plan. All money in the fund can be assumed to earn interest at a compound annual rate of 5 percent. Neglecting any charges connected with administration of the fund, how much money should be deposited in the fund at the beginning of the program in order to have enough money accumulated to replace a complete $50,000 loss after 10 years?
Show that the instantaneous frequency of the input FM signals is proportional to the number of zero crossings in the time interval t - (T1/2) to t + (T1/2), divided by T1, Assume that the modulating is essentially constant during this time interva..

What is annihilation in terms of nuclear processes? Also, what are transuranium elements and how are they synthesized? Scientists have estimated that the earth's crust was formed 4.3 billion years ago.
Forty-five kilograms of a solution containing 30 wt% ethylene glycol in water is to be extracted with furfural. Using Figures 4.14a and 4.14c, calculate:
Determine the flow rate of the refrigerant, the amount of work in the compressors, and the heat loads in all heat exchangers.
Three identical impedances of 30 ∠30° Ω are connected in delta to a three-phase 173-V system by conductors that have impedances of 0.8 + j0.6 Ω each. Compute the magnitude of the line-to-line voltage at the terminals of the load.
In the thermos shown in Fig. P8.42, the innermost compartment is separated from the middle container by a vacuum. There is a final shell around the thermos.
Consider a 1-bit version of the digital comparator shown in Figure P6.1.41. Note that the operation of this circuit is such that whichever output is 1 gives the desired magnitude comparison.
