Kindly answer the Extra question asked, stating what will happen to the Mach number if there is a pin-hole cross section. Thanks! In part c you're asked what would happen if the area were reduced morethan necessary to reach Mach 1? If you actually did this, if you reducedthe cross-sectional area to an extremely small "pin hole" size, what wouldthe Mach number be through the "pin hole"? 3.5 An airflow at Mach 0.6 passes through a channel with a cross-sectional area of 50 cm?. Thestatic pressure in the airstream is 50 kPa; the static temperature is 298 K.(a) Calculate the mass-flow rate through the channel.(b) What percent of reduction in area would be necessary to increase the flow Machnumber to 0.8? to 1.0?(c) What would happen if the area were reduced more than necessary to reach Mach 1?

Given: At inlet M1 =0.6P1 =50kPaT1 =298K

A basketball hits the outer rim of the hoop with a force of 2.5 lb at an angle of 75∘ from the horizontal before going in. The distance between the outer rim of the hoop and the backboard (point A) is 18 in. What is the moment/Torque created at the backboard (moment/Torque about A due to force of basketball) in units of in lb? Find Fx and FY and their direction of positive or negative (using the right hand rule)
A balance has a 5.0kg object at 0.5m from the fulcrum, and a 20.0kg object a certain ways in the opposite direction from the fulcrum. Where would the 20.0kg object need to be for the system to be balanced? Suppose you placed the 20.0kg object at 0.5m away from the fulcrum in the opposite direction of the 5.0kg object. This would result in an unbalanced system. Where could you then place a 10kg object to rebalance the system?
Ryan is attempting to curl a 25-kg dumbbell. He manages to get his forearm to a horizontal position, temporarily holding the dumbbell stationary. The forearm is 30 cm in length and has a mass of 4.0 kg. [Consider the forearm to have uniform mass distribution.] The distal biceps tendon is attached to the radius (one of the two bones of the forearm) 5.5 cm from the elbow. Ryan applies maximum force in an attempt to complete the curl, but his tendon ruptures (i.e., tension goes to zero). What is the total moment of inertia about the elbow (after the rupture)? Select one: a. 0.12 kg∙m2. b. 2.25 kg∙m2. c. 2.37 kg∙m2. d. 2.28 kg∙m2.
