A rock of mass m is hanging on a rope. The rock is moving upward and speeding up. How does the magnitude F of the force exerted on the rock by the rope compare with the magnitude of mg of the gravitational force

The image shows a pendulum in simple harmonic motion the pendulum starts at a and swing to e

Will give brainliest! which statement best describes the similarities between fundamental forces? electromagnetic and strong nuclear forces influence the interaction between charged particles within an atom. gravitational and magnetic forces are both types of charges that occur in nature. nuclear and magnetic forces are both related to mass and weight. strong nuclear force is most like electrical force because they are both related to distance.

Estimate the change in the gibbs energy and molar gibbs energy of 1.0dm3 of octane when the pressure acting on it is increased from 1.0 atm to 100 atm. the mass density of octane is 0.703 g cm−3
