A steel wire of length 1.6 m and diameter 0.80 mm is joined to an aluminum wire of identical dimensions to make a composite wire of length 3.2 m. Find the resulting change in length of this composite wire if an object with a mass of 5.00 kg is hung vertically from one of its ends. (Neglect any effect the masses of two wires have on the changes in their lengths.) mm

Two wires made of copper and aluminum have the same length and diameter. The wires are fused together end-to-end to form a single wire. A potential difference is applied to the ends of the wire by a battery so that current flows along the wire. What is the ratio of the electron drift velocity between the two metals, reported as ?

You have two equal masses m1 and m2 and a
spring with a spring constant k. The mass m1 is
connected to the spring and placed on a frictionless horizontal
surface at the relaxed position of the spring. You then hang mass
m2, connected to mass m1 by a
massless cord, over a pulley at the edge of the horizontal surface.
When the entire system comes to rest in the equilibrium position,
the spring is stretched an amount d1 as shown...

Two square wires are composed differently, see the figure of their cross-sections. Wire 1 is a square wire of material A but with a circular center of material C. The diameter of the circular inside is equal to the length of side of the square. The second square wire has the same cross-sectional area as the first but is entirely comprised of material A. Both wires are the same length and setup to have the same temperature difference maintained between...

Two objects with masses represented by m1 and m2 approach each other on a horizontal frictionless table with the same constant speed, v0, as measured by a laboratory observer. The objects undergo a perfectly elastic collision, and it is observed that after the collision, m2 moves off in a direction opposite its original motion with some constant speed v, and m1 is stationary. Determine the following. (a) the ratio of the two masses, m1/m2 (b) the ratio of their speeds,...

Two blocks of masses m1 and m2 are connected by a light cord that passes over a pulley of mass M, as shown. Block m2 slides on a frictionless horizontal surface. The blocks and pulley are initially at rest. When m1 is released, the blocks accelerate and the pulley rotates. The total angular momentum of the system of the two blocks and the pulley relative to the axis of rotation of the pulley isthe same at all times.proportional to I1,...
