A coin is located 22.0 cm to the left of a converging lens (f = 16.0 cm). A second, identical lens is placed to the right of the first lens, such that the image formed by the combination has the same size and orientation as the original coin. Find the separation between the lenses.
A 2.30 kg object attached to a spring moves without friction and is driven by an external force given by F = (3.00 N) sin(2pt). If the force constant of the spring is 25.0 N/m, determine the period
If the gravitational potential energy of a 30.7-kg rock is 643 J relative to a value of zero on the ground, how high is the rock above the ground
Consider Iron asteroid (density 7900 kg/m^3) shaped like a cylinder 5.0 km long and 3.0 km in diameter, How much fuel is required to spin up the asteroid
An electric motor rotating a workshop grinding wheel at 1.06 102 rev/min is switched off. How long does it take the grinding wheel to stop
A rigid steel frame above the street intersection supports standard traffic lights, each of that is hinged to hang immediately below frame. A gust of wind sets light swinging in a vertical plane. Find out order of magnitude of its period. Situatio..
A car starts from rest and travels for 6.0 s with a uniform acceleration of +2.9 m/s2. How far has it gone
At what speed (m/s) would a 1140-kg car have the same momentum as a 12,600-kg truck traveling at17.8km/hr,What is the car's change in momentum
when it is very far from the asteroid it will be traveling with speed 187 m/s. We have a large and powerful spring whose stiffness is 3.0 105 N/m. Explain how much must we compress the spring?
An express subway train passes through an underground station. It enters at t = 0 with an initial velocity of 18.5 m/s and decelerates at a rate of 0.150 m/s2 as it goes through. How fast is it going when the nose leaves the station
q1. a woman rides a carnival ferris wheel at radius 13 m completing 4.0 turns about its horizontal axis every minute.
If a disco disk is rotating with a person on it on the outer side, then if he moves inside (towards the center), the angular velocity will change-How will the energy be conserved.
A spring with a mass on the end of it hangs in equilibrium a distance of 0.4200 m above the floor. How high above the floor is the mass at the highest point in its oscillation
