Расстояние между двумя точечными зарядами q1=4×10⁶ Кл, q2=18×10⁶ Кл, равно 60см. Вычислите силу их кулоновского взаимодействия.

You've already seen the value of 9.8 in this lesson. what's this value called? what quantity does it represent?

A4.0-cm tall light bulb is placed a distance of 32.0 cm from a concave mirror having a focal length of 16.0 cm. determine the image distance

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?
