A 2.8-kg disk is constrained horizontally but is free to move
vertically. The disk is struck from below by a vertical jet of
water. The speed and diameter of the water jet are 12 m/s and 25 mm
at the nozzle exit. (a) Obtain a general expression for the speed
of the water jet as a function of height, h. (b) Find the height to
which the disk will rise and remain stationary.

(c) Find the magnitude and
direction of the minimum magnetic field required to move the wire
at constant speed.
(d) What happens if the magnetic field exceeds this minimum
value?
Consider the system pictured in the figure below. A 15.9-cm horizontal wire of mass 14.3 g is placed between two thin, vertical conductors, and a uniform magnetic field acts perpendicular to the page. The wire is free to move vertically without friction on the two vertical conductors. When a 4.75-A...

Problem 3 Consider a bead, which is free to move around the frictionless wire hoop, which is spinning at a fixed rate about its vertical axis. Derive equations of motion of the bead working in a frame rotating with the bead and compare it with Lagrangian equations for the generalized coordinate 0 derived in an inertial reference frame (the last part of this problem is an example from the textbook) 20 points

A long straight wire carrying a current of 2.03 A moves with a constant speed v to the right. A 120 turn circular coil of diameter 1.50 cm, and resistance of 3.25 u 2, lies stationary in the same plane as the straight wire. At some initial time the wire is to the left of the coil at a distance d = 13.0 cm from its center. 5.00 s later, the wire has moved to the right of the coil...

Problem 1: A car of mass 1000 kg moves at a constant speed of 20 m/s along a horizontal road where a frictional force is 200N. Calculate the power developed by the engine. If the car now moves up an incline at the same constant speed, calculate the new power developed by the engine. Assume that the frictional force is still 200 N and that sin(theta)=1/20 where theta is the angle of the incline to the horizontal. Problem 2: An...

1) [7 marks] A long straight wire hangs vertically through the middle of a metal basketball hoop of radius R = 23.0 cm. The hoop is horizontal. The wire carries a current of I = 1.56 A, moving vertically upward from the ground toward the sky. a) Sketch the magnetic field inside the hoop, as viewed from above it. b) What is the magnitude of the magnetic field at the hoop's location? c) Is there a net magnetic flux through...

Objective To determine the force generated by a jet of water striking on a surface Description of apparatus The supply is led to a vertical pipe terminating in a tapered nozzle. This produces a jet of water which impinges on the vane in the form of a Flat Plate, Hemispherical Cup, Conical Plate or 30° Angled Plate. The nozzle and vane are contained within a transparent cylinder; at the base of the cylinder there is an outlet by which the...
