When comparing two circuits, you note that circuit one has twice the voltage and half the resistance of circuit two. this means that
answers:

1. both circuits will have the same current.

2. both circuits will have alternating current.

3. circuit two will have more current.

4. circuit one will have more current.

Astone is thrown with a speed v0 and returns to earth, as the drawing shows. ignore friction and air resistance, and consider the initial and final locations of the stone. which one of the following correctly describes the change δpe in the gravitational potential energy and the change δke in the kinetic energy of the stone as it moves from its initial to its final location? options a.δpe = 0 j and δke = 0 j b.δpe is positive and δke is negative c.δpe = 0 j and δke is positive d.δpe is negative and δke is positive e.δpe = 0 j and δke is negative
