What is the average speed of a car that travels 80km in 1.5 hours

A car moves along a circular track of radius 250 ft such that its seed for a short period of time 0<_ t <_ 4s, is v = 3 (t - t^2) ft/s, where t is in seconds. a. Determine the magnitude of its acceleration when t = 3s. b.

A velocity field is given by V = (2x) i + (yt) j m/s, where x and y are in meters and t is in seconds. Find the equation of the streamline passing through (2,-1) and a unit vector normal to the streamline at (2,-1) at t=4s.

g A power amplifier has an output impedance of 47+j8Ω. It produces a no-load output voltage of 156 V at 300 Hz. Problem 11.096. a - Load impedance of a power amplifier Determine the impedance of the load that achieves maximum power transfer.

A 350 m^3 retention pond that holds rainwater from a shopping mall is empty at the beginning of a rainstorm. The flow rate out of the retention pond must be restricted to 320 L/min to prevent downstream flooding from a 6-hour storm.

While discussing armature testing: Technician A says to test for shorts, place the ohmmeter leads on a commutator segment and armature shaft. Technician B says that continuity should exist between the commutator and the armature shaft.

There are six items to be rung up in the cash register. The first item costs $15.00. Each item after that costs an additional $2.00. (item #2 costs $17, item #3 costs $19, etc.

List and briefly describe two modern's materials needs

Write the definition of a method named add that receives a reference to a Scanner object associated with a stream of input consisting of integers only. The method reads all the integers remaining to be read from the stream and returns their sum.

How are fluids distributed and transported in a fluid power system?

The sliders A and B are connected by a light rigid bar of length l = 20 in. and move with negligible friction in the slots, both of which lie in a horizontal plane. For the position where xA = 16 in., the velocity of A is vA = 3 ft/sec to the right.
