there is a legend that the inventor of chess asked fora small payment in return for the marvelous game he had developed; one grain of rice for the first square on the chess board, two for the second square, four for the third square, and so on. there are 64 squares on a chess board.
a) how many grains of rice were placed on the 16th square?
b) how many grains of rice were placed on the 64th square?
c) how many grains of rice were placed on the chess board? this problem is intended to give you some practice working with very large numbers in excel. you may want to try using the scientific format. creating a series of values from 1 to 64 for the "square number" column is a good place to use the fill handle
Discuss bracing types of buildings with real-life example. Provide photograph or sketch for each type of bracing.
The beam is to be hoisted using two chains. Determine the magnitudes of force and acting on each chain in order to develop a resultant force of 500 directed along the positive axis. Set = 41
If a logit model is estimated with coefficients of -0.543 for distance and 0.0165 for commercial space (in 1000 of ft^2), how many shopping trips will be made to each of the four shopping centers?
Important information about Mechanical engineering dynamics, A 3000 lb car rests on a horizontal street out of gas with its brakes locked.
582 nm photons are used in a photoelectric experiment. An electron is just released from metal with little or no kinetic energy at this frequency. What is the work function for this metal
Outside diameter is 10 cm and inner diameter is 9.5cm. The Mass of the ring is 16g. The force required is the weight corresponding to a mass of 16g. What's the surface tension of the liquid
To be sure that the part does not fail, we plan to ensure that the maximum applied stress is only one third of the tensile strength. We use a non-destructive test that will detect any internal flaws greater than 1.25 mm long.
Water enters a pipe at 100 psig and 70 degrees F. The density of water under these conditions is 62.3 lbm/ft^3. The pipe has an inside diameter of 4.5 inches. The mass flow rate of the water is measured to be 7500 lbm/hr.
