A 14-gauge copper wire has a diameter of 1.628 mm. What magnitude current flows when the drift velocity is 1.00 mm/s?
What is the resistance of a 25.0-m-long piece of 12-gauge copper wire having a 2.053-mm diameter?
Titanium is a transition metal used in many alloys because it is extremely strong and lightweight. Titanium tetrachloride (TiCl4) is extracted from titanium oxide (TiO2) using chlorine and coke (carbon). what mass of C is needed to react with 1.25 mol TiO2?
In the file RandomNumbers.java, write a class called RandomNumbers that has three integer instance variables: var1, var2, and var3. Write getter method for each variable: getVar1(), getVar2() and getVar3() and a RandomNumbers constructor that set the initial values of all the instance variables to 0. Then write the following 2 instance methods:
• setRandomValues( ) - accepts a low and high integer values as parameters, and sets var1, var2, and var3 to random numbers (generated using the Random class) within the range of the low and high input values (inclusive).
• getRandomValues( ) - prints out the 3 random numbers in the format: "Random values: var1 var2 var3"
Ex: If the input is:
15 20
the output may be:
Random values: 17 15 19
where 17, 15, 19 can be any random numbers within 15 and 20 (inclusive).
How long does it take for 900 to accumulate to 1000 under an interest rate of 4% per annum?
The population in country c decreases,due to lower birth rate. At the same time, at the same time there is an increase in the cost of fertilizer, which is used to grow vegetables. Explain how the market for vegetables will be affected by this changes. Clearly indicate how equilibrium price and equilibrium quantity will be affected by this changes.make a combination of diagram and verbal explanation
"The International Monetary Fund has put some conditions to address Monetary, Fiscal and Structural problems that faced the Egyptian economy."

Select and name a market of any well-known product (left upon your imagination), draw its market diagram, state and name four different factors that might cause changes, showing the changes in equilibrium price and quantity.
A vendor claims that the variance for measurement of tiles that his factory produce were 13 square feet. A sample of nine tiles was measured in square feet and the results of the tiles produced were recorded as below:
204.5 206.3 202.4 207.8 203.1 206.2 203.8 206.6 205.8
(Assuming the sample comes from a normal population)
i) Calculate the point estimate of the population mean. (2 marks)
ii) Compute the variance and standard deviation. (3 marks)
iii) Determine the estimate of 95% confidence interval for the population mean of the tiles. (5 marks)
