An applied force stretches the combination by d = 1.8 mm. How far does the point where the two wires meet move?
A mass m moves in one dimension x subject to a restoring force -kx and a damping force -γ[(x)dot]. What are the conditions for underdamped oscillations, overdamped oscillations, and critical damping?
A force does +140 J of work when it acts on a moving object and its direction is in the same direction as the object's displacement. How much work does this force do when the angle between it and the object's displacement is 56°?
An uncharged nonconductive hollow sphere of radius 18.0 cm surrounds a 18.0 µC charge located at the origin of a cartesian coordinate system. A drill with a radius of 1.00 mm is aligned along the z axis, and a hole is drilled in the sphere.
A satellite is orbiting the moon just above its surface. The centripetal force making the satellite follow a circular trajectory is just its weight, so its centripetal acceleration is about 1.622 m/s2
(a) What is the distance of a sample of blood from the rotation axis of a centrifuge rotating at 3500 rpm, if it has an acceleration of 2000g? (b) If the blood at the center of the tubes revolves around the rotation axis at the radius calculated i
For a damped oscillator with a mass of 210 g, a spring constant 61 N/m and a damping coefficient of 59 g/s, what is the ratio of the amplitude of the damped oscillations to the initial amplitude at the end of 22 cycles?
Two point charges 2.40 and 6.50are 0.100 apart. Point is midway between them; point is 8.00×10-2 from and 6.00×10-2 from . Take the electric potential to be zero at infinity. Find the work done by the electric field on a charge of 2.50
