A 60.0-cm long string with a mass 8.00 g has a tension 200 N. What is the fundamental frequency of this string?

What is a good example of instantaneous speed

Electric field of the earth. the earth has a net electric charge that causes a field at points near its surface equal to 150 n> c and directed in toward the center of the earth. (a) what magnitude and sign of charge would a 60-kg human have to acquire to overcome his or her weight by the force exerted by the earth’s electric field? (b) what would be the force of repulsion between two people each with the charge calculated in part (a) and separated by a distance of 100 m? is use of the earth’s electric field a feasible means of flight? why or why not?

Sort the images based on whether there's a force of attraction or repulsion between the magnets shown. attraction repulsion
