A frictionless, vertical wire has two metal beads on it. The beads are held 30 cm apart by horizontal magnets. If the top magnet is removed, the first bead falls under the force of gravity and strikes the second. The first bead bounces back up to a height of 10cm and the second is knocked free of the magnet and falls downward. If the two beads each have a mass of 49.7 g, what is the kinetic energy of the second immediately after impact?
What would be the potential difference VC - VB across the thin resistor if the battery emf is 4.00 volts? Suppose that the electric field in the thick wires is very small (so that the potential differences along the thick wires are negligible)
The internal energy of the coin
Visualize the one cubic centimeter as formed by stacking up identical cubes, with one copper atom at the center of each. Determine the volume of each cube.
A ball rolls off a table with a horizontal velocity of 5 m/s If it takes 0.6 secs for it to reach the floor A. What is the verticle componet of the balls velocity just before it hits the floor? (use g= 10 m/s^2) B. What is the horizontal componet ..
For instance, the flute can be described as an open-open pipe because a flutist covers the mouthpiece of flute only partially. Meanwhile, a clarinet can be described as an open-closed pipe as the mouthpiece of the clarinet is almost completely closed..
Find the resulting angular speed of the disk (in rad/s) and describe the direction of rotation.
A 15g rifle bullet traveling 220 m/s buries itself in a 3.5 kg pendulum hanging on a 2.7 m long string, which makes the pendulum swing upward in an arc. Determine the horizontal component of the pendulum's displacement.
How numerous atoms does each hand contain
The velocity component of the particle at x = 8.0 m is 2.8 m/s. Illustrate what is the acceleration component during this time interval?
A piece of Nichrome wire has a radius of 5.0 x10-4 m. It is used in a laboratory to make a heater that dissipates 2.00 x10^2 W of power when connected to a voltage source of 120 V. Ignoring the effect of temperature on resistance, estimate the req..
A speedboat starts from rest and accelerates at +2.32 m/s2 for 6.78 s. At the end of this time, the boat continues for the additional 5.34 s with an acceleration of +0.677 m/s2. Following this, the boat accelerates at -0.686 m/s2 for 8.68 s.
Create a graph of x-position, x-velocity, and x-acceleration versus time and a graph of y-position, y-velocity, and y-acceleration versus time.
