The alignment between the magnetic media and head in a magnetic storage system affects the system's performance. Suppose that $10 \%$ of the read operations are degraded by skewed alignments, $5 \%$ of the read operations are degraded by off-center alignments, and the remaining read operations are properly aligned. The probability of a read error is 0.01 from a skewed alignment, 0.02 from an off-center alignment, and 0.001 from a proper alignment. (a) What is the probability of a read error? (b) If a read error occurs, what is the probability that it is due to a skewed alignment?

Water is to be pumped from the large tank shown ir Fig. P5.1 19 with an exit velocity of $6 \mathrm{m} / \mathrm{s}$. It was determined that the original pump (pump 1) that supplies 1 kW of power to the water did not produce the desired velocity. Hence, it is proposed that an additional pump (pump 2 ) be installed as indicated to increase the flowrate to the desired value. How much power must pump 2 add to the water? The head loss for this flow is $h_{l}=250 Q^{2}$, where $h_{l}$ is in $\mathrm{m}$ when $Q$ is in $\mathrm{m}^{3} / \mathrm{s}$.

INSTANT ANSWER

A simple yet efficient method to calculate the square root of a number is variously called the divide- and-average method. To find the square root of a number (a) 1. Begin with an initial estimate \( x \). 2. Divide the number by the estimate (i.e., a/x), to get a new estimate 3. Average the original estimate and the new estimate (i.e., \( (x+a / x) / 2 \) ) to get a new estimate 4. Return to step 2 .

Please solve the following question with VBA programming. The program is executed with a loop. Economic formulas are available to compute annual payments for loans. Suppose that you borrow an amount of money P and agree to repay it in n annual payments at an interest rate of i. The formula to compute the annual payment A is: A=(P* (i*(1 + i)^n)/(((1+i)^n) - 1)) Write a program to compute A. Test with P=50000 TL and an interest rate of % 5 (i=0.05). Interest rate and loan amount are your inputs; interest rate should be requested as a percentage. Compute results n= 1, 2, 3, 4, and 5 and display. You are required to use a Do Until loop in the program.
