Which of the following is the equation for gravitational potential energy? a. pe = mgh b. pe = mv c. pe = 1/2(mv) d. pe = fd

B is momentum.  It's a quantity of motion, or "how much stuff is moving"

C is *almost* kinetic energy but it's missing an exponent of 2 on the velocity, v.

D is an amound of work done in moving something a distance d while applying a constant force F.

That leaves A.  This is the potential energy of an object of mass m, in a gravitational acceleration g, at a height h above the reference point (usually the ground)

Answer is A- mgh.

The equation for gravitational potential energy is mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m/s ∧2 on Earth), and h is the height above the ground in meters.

Gravitational potential energy is defined as the  energy an object possesses due to its position in a gravitational field.

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.

explanation:

considering the bohr theory, the type of connection that requires the transfer the answer conuldn't be right
