Can a stationary charge experiences a magnetic force?
Can a stationary charge experiences a magnetic force? There is no magnetic force on static charges. However, there is a magnetic force on moving charges. When charges are stationary, their electric fields do not affect magnets. But, when charges move, they produce magnetic fields that exert forces on other magnets. Why is a stationary charge […]
How do you add a function?
How do you add a function? Operations on Functions: Adding and Subtracting Functions Addition. We can add two functions as: (f + g)(x) = f(x) + g(x) Example: Subtraction. We can subtract two functions as: (f – g)(x) = f(x) – g(x) Example: Multiplication. (f•g)(x) = f(x)•g(x) Example: f(x) = 3x – 5 and g(x) […]
