A 4.5 kg block is pulled across a table by a horizontal force of 42 N. The frictional force opposing the motion is 7.5 N. Calculate the acceleration of the object.

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.
