Determine the radius of the spherical wedge whose volume 12 m3 with a central angle of 1.80 radians.


A closed right cylindrical tank with a height of 8 m and 3 m in diameter contains water to a depth of 5m. If the tank is laid in a horizontal position, find the depth of water.


The volume of a frustum of a rectangular pyramid is 79.17 m3 with an altitude of 5 m. If the upper base has dimensions of 2.50 m x 4.0 m, find the area of the lower base.


If two cylinders, both of radius 1m, intersect at right angles, Find the volume of the intersection.


The shaded region below is the common area to four semicircles whose diameters

are the sides of the square with side length 4x. Find the area of the shaded region in

terms of x.


The two circles below have equal radii of 4 units each and the distance between their centers is 6 units. Find the area of the shaded region.


1-9 We have two Zener diodes with silicon material, Uzl 6V, Uz2 = 9V. When they are used in series in the circuit, determine all the possible voltages we can get. And how about the possible voltages when they are used in parallel? 1-10 Zener diode circuit is shown below, Uz = 6V =10mA, max dissipate power PzM 500ohm Izmin = 200mW, current limitation resistance R Try to determine: 1). When U-20V, R, - 12 Uo = ? 2). When U,-20V, R, =1002 Uo ? 3) when -20V, R regularly? can the Zener diode work 4) when U-7R, is varying, can the Zener diode work regularly? Uo 1-29 1-10

When a certain perfect gas is heated at constant pressure fr 15 degree C to 95 degree C, the heat required is 1136KJ/Kg.When the same gas is heated at constant volume between the same temperatures the heat required is 808KJ/Kg. Calculate the Cp, Cv, R and molar mass of the gas.


Write a assembly program that takes two 2-D matrixes A and B. Add value of the matrixes and store it in different matrix called C. NB: Implement the above problem inside Main Procedure.


A thermocouple is used to measure the temperature of air flowing through a duct. The heat transfer coefficient between the air and the thermocouple is proportional to v0.8, where v is the average velocity of the air within the duct. Assume that the heat transfer by radiation from the duct walls to the thermocouple bead is linearly proportional to the temperature difference between them. For v= 5 m/s, the thermocouple reads 50
