Siven an element's atomic number and mass number, how can you tell the number of protons and neutrons in its nucleus?
jumber of protons = atomic number; number of neutrons = mass number - atomic number
number of protons = atomic number; number of neutrons = mass number + atomic number
number of protons = mass number; number of neutrons = atomic number - mass number

As part of your daily workout, you lie on your back and push with your feet against a platform attached to two stiff springs arranged side by side so that they are parallel to each other. when you push the platform, you compress the springs. you do an amount of work of 79.0 j when you compress the springs a distance of 0.230 m from their uncompressed length. (a) what magnitude of force must you apply to hold the platform in this position? (b)how much additional work must you do to move the platform a distance 0.230 m farther? (c) what maximum force must you apply to move the platform a distance 0.230 m farther?
