a) A rectangular block of pure silver measures 6 x 6 x 40 (cm). Determine the resistance between the opposite sides that are farthest apart:
b) Determine the dimentions (in cm) of a rectangular aluminum block (also 40 cm long) that would have the same resistance between the farthest opposing sides as the silver block (part a):
Jack and Jill are standing on a crate at rest on the frictionless, horizontal surface of a frozen pond. Jack has a mass of 75.8kg, What is the final speed of the crate if both Jack and Jill jump simultaneously and in the same direction
A solid sphere of mass 6.0 kg is mounted on a vertical axis and can rotate freely without friction, What is the speed of the block after it has fallen 80 cm
Compute the required time by the current to reach an initial value in an inductive discharge circuit.
The spring is then released. If the mass is attached to the spring, explain how far up the slope will the mass move before coming to rest? Express your answer using two significant figures.
The coefficient of kinetic friction for wood sliding on wood is 0.20. Illustrate what is the speed of the bullet?
The last piece has 4 times as much mass as each of the other pieces. Illustrate what is the magnitude of the velocity of the last piece?
The inner surface is negative relative to the outer surface. Explain how much work is required to eject a positive sodium ion (Na+) from the interior of the cell?
Assume the masses described in the preceding problem are 1kg and 100kg in that order. Compare the accelerations while they are interchanged.
Imagine that we connect a 10-mH coil to a battery through a resistor, and it settles down to conducting 1.0A. How much energy is now stored in its magnetic field
Initially stationary (the train starts at rest), a train has a constant acceleration of 0.6 m/s2, What is its speed after 21 s
What is the electric potential energy of the system? (Take as zero the potential energy of the three charges when they are infinitely far apart.)" Use = 8.85 10 12 for the permittivity of free space.
You drive your 1,345-kg car at a constant speed of 23 mph a distance of 71 m down a ramp that has a grade of 14 %. Define positive direction in the forward direction
