Create a simple balance using a ruler as the balance beam and a pencil as the fulcrum. Put 2 nickels stacked together on one side of the ruler and a single nickel on the other side so that the ruler is balanced. Does the distance from the fulcrum to the 2 nickels = 1/2 the distance to the single nickel? How would you account for any discrepancy?

Proper Length

The theory of special relativity explains the connection between space and time to objects that move in a straight line at a constant speed. The objects move at the speed of light. When an object approaches light speed, its mass is endless and cannot move faster than light. The most crucial postulate of Einstein's special relativity is that the laws of nature do not change in each frame of reference.

Question

Create a simple balance using a ruler as the
balance beam and a pencil as the fulcrum.
Put 2 nickels stacked together on one side of
the ruler and a single nickel on the other side
so that the ruler is balanced. Does the
distance from the fulcrum to the 2 nickels =
1/2 the distance to the single nickel? How
would you account for any discrepancy?

Review. After removing one string while restringing his acoustic guitar, a student is distracted by a video game. His experimentalist roommate notices his inattention and attaches one end of the string, of linear density = 3.00 103 kg/m, to a rigid support. The other end passes over a pulley, a distance, = 64.0 cm from the fixed end, and an object of mass m = 27.2 kg is attached to the hanging end of the string. The roommate places a magnet across the string as shown in Figure P23.19. The magnet does not touch the string, but produces a uniform field of 4.50 mT over a 2.00-cm length of the string and negligible field elsewhere. Strumming the string sets it vibrating vertically at its fundamental (lowest) frequency. The section of the string in the magnetic field moves perpendicular to the field with a uniform amplitude of 1.50 cm. Find (a) the frequency and (b) the amplitude of the emf induced between the ends of the string.
