- The rods and cones in our eyes adjust to the disappearance of the lilac dots after a few seconds and become tired. In the absence of the lilac dot, our eyes engage cones which process colors at the opposite end of the spectrum; in this case, green.
- The conducting rod shown in the figure has length L and is being pulled along horizontal, frictionless, conducting rails at a constant velocity. The rails are connected at one end with a metal strip. A uniform magnetic field, directed out of the page, fills the region in which the rod moves.
The object moving up an inclined plane needs to move the entire length of the slope of the plane to move the distance of the height. For example, if you have a ramp with a slope length 20 meters that rises 5 meters high, then your trade-off is moving the 20 meters distance versus lifting straight up 5 meters, and your mechanical advantage is 4.
- There are two commonly used units of measurement for angles. The more familiar unit of The reason that this definition works is that the length of the subtended arc is proportional to the radius of the circle. If the gauge is 5 feet, find the difference in length of the two rails to the nearest half-inch.
Let the copper rod be oriented along y-axis and current flows along +y-axis and that it moves along The coefficient of static friction between rod and rails is #mu_s#.

- Ans: 2.Two point masses of 0.3kg and 0.7kg are fixed at the ends of a rod which is of length 1.4m and of negligible mass. Ans: 4.A smooth sphere A is moving on a frictionless horizontal plane with angular speed co and centre of mass velocity v. It collides elastically and head on with an identical...
A straight horizontal conducting rod of length 0.45 m and mass 60 g is suspended by two vertical wires at its ends. A horizontal magnetic field of 0.26 T normal to the length of the conductor should be set up in order to get zero tension in the wire.
- Physics Physics for Scientists and Engineers, Technology Update (No access codes included) A conducting rod of length ℓ moves on two horizontal, frictionless rails as shown in Figure P31.26. If a constant force of 1.00 N moves the bar at 2.00 m/s through a magnetic field B that is directed into the page (a) what is the current through the 8.00-Ω resistor R ?
A 2.0-kg rod that has a length of 1.0 m and a resistance of 4.0 slides with constant speed down a pair of frictionless vertical conducting rails that are joined at the bottom. Other than the rod, the rest of the circuit is resistanceless. A uniform magnetic field of magnitude 3.0 T is perpendicular to the plane formed by the rod

A magnetic field of magnitude B = 0.350 T points out of the page. (a) If the rails are separated by L = 25.0 cm and the speed of the rod is 55.0 cm/s, what emf is generated? (b) If the rod has a ...
5. A conducting rod with a length of 0.45 m makes a contact with two conducting and parallel rails. The rails are connected to a 2.5 Ω resistor; ignore the resistance of the rod and rails. A constant force F moves the rod at a constant speed 4.2 m/s to the right with no friction between the rod and rails. The apparatus is placed in a uniform magnetic field 1.8 T that is perpendicular to the rails and the rod.
