If a = 2.0 cm, b = 5.0 cm, and i = 20 a, 6.0 μt is the magnitude of the magnetic field at the point p, So the correct option is (a).
The magnetic influence on moving electric charges, electric currents, and magnetic materials is described by a magnetic field, which is a vector field. A force perpendicular to the charge's own velocity and the magnetic field acts on it when the charge is travelling through a magnetic field.
= μ
i 
/ 
= μ i / 
As, is moving down and is moving up so,
- = (μ i / ) - [μ i / ]
- = μ i 24 / 
- = 
- = 5.98×
T ≈ 6μT
Therefore, 6.0 μt is the magnitude of the magnetic field .

The conservation of the mass of fluid through two sections (be they A1 and A2) of a conduit (pipe) or current tube establishes that the mass that enters is equal to the mass that exits. Mathematically the input flow must be the same as the output flow,
The definition of flow is given by
Where
V = Velocity
A = Area
The units of the flow of flow are cubic meters per second, that is to say that if there is a continuity, the volume of input must be the same as that of output, what changes if the sections are modified are the proportions of speed.
In this way
Answer:
Explanation:
The sealed bottle serves as an open system for the water molecules, thus heat energy can be exchanged with its surroundings. When the bottle is placed in a warm environment, there would be a gradual increase in the thermal energy of the molecules of water due to a change in the temperature of its surroundings.
Thus, the molecules of water closer to the boundary of the bottle absorbs heat, becomes lighter and changes position. This gradual process continues until all molecules attains an average temperature which equals that of the surroundings of the bottle.
Therefore, both the thermal energy and temperature of the water increases.
Answer:
Correct answer is gaseous state
Explanation:
in gaseous state , the bonding between the molecules of matter is less compared to that in other state.
