Two long parallel wires carry currents of 3.05 A 3.05 A and 6.69 A 6.69 A . The magnitude of the force per unit length acting on each wire is 7.33 × 10 − 5 N / m 7.33×10−5 N/m . Find the separation distance d d of the wires expressed in millimeters.

How does the amount of energy required to hold each proton and neutron in the nucleus compare to the energy released when they are removed?

A0.580-kg rock is tied to the end of a string and is swung in a circle with a radius of 0.500 meters. the velocity of the rock is 4.50 m/s. what is the centripetal force acting on the rock? 15.5 n 5.22 n 69.8 n 23.5 n

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?
