Answer:
option (D
Explanation:
Torque is given by
torque = N x i x A x B x sinФ
where, N is number of turns, A is area, b is the magnetic field and Ф be the angle between the area vector and the magnetic field vector, i be the current.
So, torque depends on the current.
option (D)
Static electric fields are caused by charged particles when the atoms which compose the particle will have the same number of electrons as protons.
Each point in space has an electric field associated with it when the charge of any kind is present. The value of E, often known as the electric field strength, electric field intensity, or just the electric field, expresses the strength and direction of the electric field.
Both the electromagnetic wave produced by a radio broadcast monopole antenna and the field created in the dielectric of a parallel-plate capacitor are examples of electric fields (which create a time-varying field). Every place in space where a charge, regardless of its shape, is present is said to have an electric field, which is an electric attribute. The electric field's equation is given as E = F / Q.

The 78g box, since it has less weight, would accelerate faster. If you had a frictionless surface, and you conducted this experiment, both boxes, without any outside forces, would accelerate at the same rate forever. However, in this problem we must assume the surface is not frictionless. Friction is determined by weight; the more weight, the more friction. Since the 78g box has less weight, it has less friction, making it easier to push with less force.
Answer:
Thermal energy
Explanation:
The thermal energy associated with the random motions of the atoms or molecules.
When the temperature of the substances rise then their molecule starts to vibrate within the system and the energy associated with the vibration of the molecule is known as thermal energy.The responsible factor for the rise in temperature is thermal energy.
Therefore answer is --
Thermal energy
