Physics hw should be easy but I forgot how to find frequency A spring vibrates with a frequency of 2.20 Hz when a mass of 0.500 kg is hung from it. What will its frequency be if a 1.00 kg mass is hung from it?

1.what is where an object is located 2. what is how fast an objects speed is changing 3. what is how fast an object is moving

(a) calculate the number of electrons in a small, electrically neutral silver pin that has a mass of 10.0 g. silver has 47 electrons per atom, and its molar mass is 107.87 g/mol. (b) imagine adding electrons to the pin until the negative charge has the very large value 1.00 mc. how many electrons are added for every 109 electrons already present

Select the correct answer. what does the process of natural selection involve?
