Question Solved1 Answer 1.       A 60 mm jet strikes a stationary frictionless curved vane, at 40 m/s velocity, tangentially. If the jet is deflected by an angle of 45° by the vane due to this impingement, determine the force exerted by the jet on the plate. 2.       A jet of water, 10 cm in diameter, strikes a stationary curved blade with 20 m/s velocity and gets deflected by 30° with respect to the direction of the impinging jet. The exit velocity is reduced by 10% due to frictional effects. Calculate the component of force on the vane   (i) in the direction of initial jet direction and   (ii) in the normal direction to the jet

2 . Real versus nominal GDP Consider a simple economy that produces two goods: beers and paper plates. The following table shows the prices and quantities of the goods over a three-year period. Year Beers Paper plates Price Quantity Price Quantity (Dollars per beer) (Number of beers) (Dollars per paper plate) (Number of paper plates) 2018 2 265 1 160 2019 2 135 4 230 2020 2 135 4 180 Use the information from the preceding table to fill in the following table. Year Nominal GDP Real GDP GDP Deflator (Dollars) (Base year 2018, dollars) 2018       2019       2020       From 2019 to 2020, nominal GDP    , and real GDP    . The inflation rate in 2020 was    . Why is real GDP a more accurate measure of an economy's production than nominal GDP? Real GDP measures the value of the goods and services an economy produces, but nominal GDP measures the value of the goods and services an economy consumes. Real GDP is not influenced by price changes, but nominal GDP is. Real GDP includes the value of exports, but nominal GDP does not.

Solve the following Bernoulli equations: a) x2y' + 2y = 2e1/xy1/2 answer: y = e2/x(c-1/x)2 b) xy' + y = x4y4 y(1) = 1/2 answer: y = 1/x(11-3x)1/3

At its Ames Research Center, NASA uses its large “20 G” centrifuge to test the effects of very large accelerations (“hypergravity”) on test pilots and astronauts. In this device, an arm 8.84 m long rotates about one end in a horizontal plane, and an astronaut is strapped in at the other end. Suppose that he is aligned along the centrifuge’s arm with his head at the outermost end. The maximum sustained acceleration to which humans are subjected in this device is typically 12.5g. (a) How fast must the astronaut’s head be moving to experience this maximum acceleration? (b) What is the difference between the acceleration of his head and feet if the astronaut is 2.00 m tall? (c) How fast in rpm 1rev>min2 is the arm turning to produce the maximum sustained acceleration?
