A vertical bar and two parallel horizontal rails lie in the plane of the page. The parallel rails run from left to right, with one a distance ℓ above the other. The left ends of the rails are connected by a vertical wire containing a resistor R. The vertical bar lies across the rails to the right of the wire. Force vector Fapp points from the bar toward the right.In the figure below, a metal bar sitting on two parallel...
Three objects are connected by massless wires over a massless frictionless pulley as own in the figure. The tension in the wire connecting the 10.0-kg and 15.0-kg objects is 6) measured to be 133 N. What is the tension in wire A? (5 POINTS) 15.00 kg 133 N 10.00 kg

A 14.3 kg k g load is pulled straight up by a massless rope from the ground to the roof of a building, at a constant acceleration of 0.90 m/s2 m / s 2 . During the upward motion, the tension in the rope is 150 N 130 N 140 N 13 N
A horizontal wire is hung frem the celing of a room by two massless strings. The wire has a length of 0.11 m and a mass of 0.009 kp. A unifom magnetic field of magnitude 0.065 T is directed from the ceiling to the floor. When a current of - 23 A exists in the wire, the wire swings upward and, at equi ibrium, makes an angle with respest to the vertical, as the drawing shows. Find (a) the angle...
Two boxes (connected by a massless wire) are hanging from a crane, as shown in the figure below. The boxes are being lifted up by the crane while their speed is decreasing (in other words, the boxes are slowing down). The mass of box B is double the mass of box A (mB = 2m/). T denotes tension in the wire connecting box A to the crane. FAonB and FBonA denote forces exerted by the boxes on each other through...
1. A horizontal wire is hung from the ceiling of a room by two massless strings. The wire has a length of 0.11 m and a mass of 0.005 kg. A uniform magnetic field of magnitude 0.055 T is directed from the ceiling to the floor. When a current of I = 34 A exists in the wire, the wire swings upward and, at equilibrium, makes an angle φ with respect to the vertical, as the drawing shows. Find (a)...
A mass m = 5 kg is connected to an ideal massless spring of spring constant k = 100 N/m. At initial time t = 0 s, the mass passes the equilibrium position moving to the left (defined as the negative x direction) with a velocity vx0 = -5 m/s. Part (a): What is the first time after the initial time that the mass will be at the rightmost displacement? What is the quickest approach to this problem?
Two blocks, of weights 2.5 N and 6.6 N, are connected by a massless string and slide down a 37° inclined plane. The coefficient of kinetic friction between the lighter block and the plane is 0.14; that between the heavier block and the plane is 0.20. Assuming that the lighter block leads, find (a) the magnitude of the acceleration of the blocks and (b) the tension in the string.
Two blocks, of weights 2.9 N and 6.5 N, are connected by a massless string and slide down a 45° inclined plane. The coefficient of kinetic friction between the lighter block and the plane is 0.062; that between the heavier block and the plane is 0.18. Assuming that the lighter block leads, find (a) the magnitude of the acceleration of the blocks and (b) the tension in the string.
