Calculate the unknown mass of the cylinder m and calculate the force of tension A cylinder of unknown mass m is attached to a cord that is wrapped around a 3 kg pulley shaped as a hoop. The pulley-cylinder system is initially at rest. Once the cylinder is released, the linear acceleration of the pulley is 2m/s^2. Assume the axle of the pulley to be frictionless. The moment of inertia for a hoop is mr^2.

The metric unit of electrical power is the watt volt ampere ohm

Two pans of a balance are 24.1 cm apart. the fulcrum of the balance has been shifted 1.33 cm away from the center by a dishonest shopkeeper. by what percentage is the true weight of the goods being marked up by the shopkeeper? assume the balance has negligible mass. answer in units of %.

Calculate the minimum energy required to remove one proton from the nucleus 126c. this is called the proton-removal energy. (hint: find the difference between the mass of a 126c nucleus and the mass of a proton plus the mass of the nucleus formed when a proton is removed from 126c.) express your answer with the appropriate units. emin e m i n = nothing nothing request answer part b how does the proton-removal energy for 126c compare to the binding energy per nucleon for 126c, calculated using eb=(zmh+nmn−azm)c2?
