The two long straight wires are separated by a distance of d = 0.40 m. The currents are to the right in the upper wire and to th
e left in the lower wire. What is the direction of the magnetic field at point P, that is a distance d/2 below the lower wire?
1 answer:
Answer:
Out of the page
Explanation:
At point P, Using right hand rule, the direction of magnetic field due to current flowing towards left in lower wire comes out to be in outward direction.
At point P, Using right hand rule, the direction of magnetic field due to current flowing towards right in upper wire comes out to be in inward direction.
we know that magnetic field at a point by a long current carrying wire depends inversely on the distance from the wire. hence greater the distance, weaker will be the magnetic field.
Since point P is farther from upper wire and closer to lower wire, the magnetic field in Outward direction by the lower wire is stronger as compared to the magnetic field by the upper wire in inward direction.
hence magnetic field at point P comes out to be in Outward direction.

Answer:
486nm
Explanation:
in order for an electron to transit from one level to another, the wavelength emitted is given by Rydberg Equation which states that
Hence the photon must possess a wavelength of 486nm in order to send the electron to the n=4 state
Answer:
The capillary rise of the glycerin is most nearly
Explanation:
From the question we are told that
The diameter of the glass tube is
The density of glycerin is
The surface tension of the glycerin is
The capillary rise of the glycerin is mathematically represented as
substituting value
Therefore the height of the glass tube the glycerin was able to cover is
