Ajet of water moving at 20 m/s impinges on a symmetrical curved vane shaped to deflect the jet through 120o (i. e. the blade angles β1 and β2 are both 30o ). if the vane is moving at 5 m/s, find the angle of the jet so that there is no shock at the inlet. also determine the absolute velocity of exit in magnitude and direction. also determine the work done.

Aforce of 200 n is applied to an input piston of cross-sectional area 2 sq. cm pushing it downward 2.8 cm. how far does the output piston of cross-sectional area 12 sq. cm move upward? show all work.

Apositive charge moves in the direction of an electric field. which of the following statements are true? check all that apply. check all that apply. 1.the potential energy associated with the charge decreases. 2. the electric field does positive work on the charge. 3. the electric field does negative work on the charge. 4. the potential energy associated with the charge increases. 5. the electric field does not do any work on the charge. 6. the amount of work done on the charge cannot be determined without additional information.
