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.

When considering gravity acceleration and the force of acceleration, what must be true? a. the direction of acceleration must be perpendicular to the direction of the force. b. the direction of the force and the direction of acceleration must be the same as each other. c. the direction of the force and the direction of acceleration must be opposite of each other. d. the mass of the body must be the same as the acceleration of the body.

In the circuit shown below, with each bulb holding a resistance of 60 ohms, how many amps of current are flowing? express your number as a decimal.

The frequencies refer to the sample data collected from a population of interest when performing a hypothesis test comparing two or more population proportions.
