A particle of mass m = 4.0 kg is acted upon by four forces of magnitudes. F1 = 10.0 N, F2 = 40.0 N, F3 = 5.0 N, and F4 = 2.0 N , What is the acceleration of the particle?

Debbie places two shopping carts in a cart corral she pushes the first cart which then pushes a second cart what force is being exerted

A10nc charge sits at a point in space where the magnitude of the electric field is 1500 n/c. what will the magnitude of the field be if the 10 nc charge is replaced by a 20 nc charge? assume the system is big enough to consider the charges as small test charges.

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?
