A0.160 kg ball attached to a light cord is swung in a vertical circle of radius 70.0 cm. at the top of the swing, the speed of the ball is 3.26 m/s. the centre of the circle is 1.50 m above the floor.
calculate the speed of the ball when the cord is 30.0̊ below the horizontal.

Amajor difference radio waves, visible light, and gamma rays is the of the photons, which results in different photon frequencies and wavelengths

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?
