Hello. This question is incomplete. The full question is:

"A wire is wrapped multiple times around a galvanized or aluminum nail and then each end of the wire connected to a battery for some period of time. What happens when the nail is then positioned next to a paper clip and why

A)the paper clip is repelled away from the nail because an electromagnetic field magnetized the nail . B)the paper clip is attracted toward the nail because an electromagnetic field magnetized the nail . C)no effect at all on the paper clip from the wire or the nail . D)the paper clip straightens out because of Ohm's Law."

A)the paper clip is repelled away from the nail because an electromagnetic field magnetized the nail .

Explanation:

An electromagnetic field is a system formed by electric charges where a magnet manifests its action by repelling, or attracting bodies. This system is formed through the passage of an electric current, through conductors, as wires and using an electrical energy source, such as a battery, for example.

As mentioned earlier, this system can establish the attraction or the removal of two bodies. An example of this can be seen in the question above, where a wire is wound several times around a galvanized or aluminum nail and then each end of the wire is connected to a battery for a period of time. If a nail approaches these systems, a magnetized electromagnetic field is created around that nail. The result of this will be that the paper clip will be repelled, as it does not contain attraction poles with the nail.

Answer from: Quest

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.

Answer from: Quest

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.

Aprojectile is launched from ground level with an initial velocity of v 0 feet per second. neglecting air resistance, its height in feet t seconds after launch is given by s equals negative 16 t squared plus v 0 t. find the time(s) that the projectile will (a) reach a height of 192 ft and (b) return to the ground when v 0equals112 feet per second. (a) find the time(s) that the projectile will reach a height of 192 ft when v 0equals112 feet per second. select the correct choice below and, if necessary, fill in the answer box to complete your choice.
