Aloop of wire carries a current. the resulting magnetic field . points toward the loop at all pointsb. points away from the loop at all pointsc. is similar to that of a bar magnet in the plane of the loopd. is similar to that of a bar magnet perpendicular to the plane of the loop

d-similar to that of a bar magnet perpendicular to the plane of the loop

Explanation:

Current is rate of flow of charge. Magnetic field due to a current carrying wire depends on the current in the wire and the distance of the point from the wire. The direction of the magnetic field is perpendicular to the wire. This is demonstrated in Flemming's Right hand rule

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
