(01.02 MC) A student made the table shown to list some contact and non-contact forces. Examples of Forces Contact Forces Non-Contact Forces The force applied by a magnet on an iron nail The force applied by an electromagnet on a wire The force applied by a student on a door to open it The force applied by the planets on each other Which statement best explains why the table is incorrect? (3 points) a Magnetic force is a force acting at a distance. b The student applies a non-contact force on the door. c The electromagnet and wire have to be in contact to apply the force. d Gravitational force acts between planets only when they are in contact.

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?
