Design a converging-diverging nozzle for a spacecraft thruster that has an exit Mach number of 5.00 when using compressed helium at 50.0 MPa, and 0.00°C. Assume the nozzle exhausts into a total vacuum.
Plot the nozzle diameter vs. length along the nozzle, keeping the angle of the diverging wall to less than 10o with the horizontal to prevent flow separation.
Show the positions along the nozzle where M = 1, 2, 3, 4, and 5. Determine the mass flow rate through your nozzle.
A 3.68-kg fish swimming 1.33 m/s swallows an absent-minded 6.42-kg fish swimming toward it at a velocity that brings both fish to a halt immediately after lunch

A 5.0 µC point charge is placed in an external uniform electric field of 2.00 104 N/C. At what distance from the charge is the net electric field zero
A 7.0 gram bullet shoots into 1.5 kilogram ballistic pendulum. Bullet emerges with velocity 200 m/s, and pendulum rises to max of12 centimeter. Compute what the initial speed of bullet
An air-filled capacitor consists of two parallel plates, each with an area of 7.06 cm2, separated by a distance of 1.28 mm, Find the capacitance
The electromagnetic wave that delivers a cellular phone call to acar has a magnetic field with an rms value of 1.38E-10 T. The wavepasses perpendicularly through an open window, the area of which is0.244 m2.
Consider the design of a solar-powered alternate power generation infrastructure that could maintain sufficient electrical power to meet current US annual demand.
An object, at the top of a very tall building, is released from rest and falls freely due to gravity. Neglect air resistance and compute distance covered by the object between times t1 = 5.5 s and t2 = 7.9 s after it is released.
