Study the scenario.
an object is at rest. at five seconds, someone comes over and pushes the object forward with a force of 10 n.
which of the following choices describes the force needed to keep the object in static equilibrium?
1. a force of 10 n must be exerted in a backward direction on the box at any time after five seconds so that the forces are balanced and the object moves at a constant velocity.
2. a force greater than 10 n must be exerted in a forward direction on the object at exactly five seconds to prevent the object from moving.
3. a backward force of 10 n must be exerted on the box at exactly 10 seconds so that the forces are balanced and the object remains at rest.
4. there is no way to keep the object in static equilibrium once a force has been exerted on it.

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?

An electric power distributor charges residential customers $0.10 per kilowatt-hour (kwh). the company advertises that "green power" is available in 150 kwh blocks for an additional $4 per month. (green power is generated from solar, wind power, and methane sources.) if a certain customer uses an average of 391 kwh per month and commits to one monthly 150 kwh block of green power, what is her annual power bill
