The image above shows two opposite forces acting on a rolling cart. What can we say is true about the affect of the forces on the cart?

It cannot be determined without knowing which person is stronger

It cannot be determined because one person is taller than the other

The forces are unbalanced and the net force moves the cart to the left

The forces are unbalanced and the net force moves the cart to the rigjt

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.

probably not the "magnets"in the magnet, so to speak, are thought to be electrons orbiting in shells. vurrent loops two sides to the loop
