Question Solved1 Answer 1. A 15 cm diameter jet of water with a velocity of 15 m/s strikes a plate normally. If the plate is moving with a velocity of 6 m/s in the direction of the jet, (a) calculate the work done per second on the plate and the efficiency of energy transfer by the jet. (b) What would be the efficiency if the jet impact is on a series of blades mounted on a wheel? 2. A 10 cm diameter free jet of water having a velocity of 30 m/s impinges on a plane, smooth plate at angle of 45° to the normal to the plate. (a) What will be the force due to jet impingement on the plate and work done per second when (i) the plate is stationary, and (ii) when moving in the direction of the jet at 6.0 m/s velocity. (b) What will be the force due to jet on the plate when the plate is moving against the jet direction at 6.0 m/s velocity?

undefined 19 If we multiply a complex number z = reis by ei', we get ei®z = re (6+0), that is, a complex number with the same r but with its angle increased by e. We can say that the vector r from the origin to the point z= x+iy has been rotated by angle e as in Figure 7.4 to become the vector R from the origin to the point Z = X +iY. Then we can write X +iY = ei®z = ei® (x + iy). Take real and imaginary parts of this equation to obtain equations (7.12).

Problem 5 6/9 points (graded) An alpha particle, consisting of two protons and two neutrons, is located at < -32,0,0 > nm and produces an electric field in all of space. A neutral Krypton atom, with polarizability a = 5.0 * 10–39 oʻm is brought to the location < 14,0,0 > nm. What is the resulting dipole moment ſ that the Krypton atom attains? (Recall the relationship between an applied electric field and the resulting dipole moment is praĒ). Please answer as a vector in Coulomb meters. 0 0 0 C*m X ✓ ✓ 0 0 0 Since the neutral Krypton atom is polarized, it produces an electric field. In fact, the electric field that it produces looks like the field of an electric dipole, whose magnitude is given by lĒnasial = 2.pl. Compute the vector electric field due to the polarized Krypton atom at the position of the alpha 460 particle. Please answer as a vector in Newtons per Coulomb. 0 0 0 * 2 X ✓ 0 0 0 What is the net force exerted on the alpha particle? Please answer as a vector in Newtons. 0 0 0 IN 2 2 X ✓ ✓ 0 0 0

Kevin is receiving medical treatment for a disease wheremarijuana would help to ease his pain and suffering. In Oregon,medical marijuana is legal to purchase and use for medicinalreasons IF you have been approved by an M.D. to purchase it.Kevin's M.D. gives him a prescription for medical marijuana. Andrewthen moved to Texas. He continued to use marijuana to help to easehis pain and is arrested for violating Texas state law. Kevinargued that the highest Supreme Court of Oregon permits the use ofmedical marijuana. To-date, the federal law prohibits the use orpossession of marijuana - prescribed or not. Kevin argues that theruling of the Oregon Supreme Court would be binding precedent.a. Is Kevin correct in his argument?b. Can a state's highest court rule that it's law and rulingsare precedent over another state's law?c. If the Texas court rules against Kevin, do you think this isfair? Give your reasoning.d. Which court would have jurisdiction? Be specific. Venue isappropriate where?e. How would Kevin fair in a federal court?
