The observation location A is located at < 0.112, 0.247, 0 > m. The conventional current running through the wire is 7.5 amperes. In this exercise you will calculate the magnetic field at the observation location due only to segment 4 of the wire.

What is the direction of conventional current in this wire?

Positive direction

Explanation:

We know that the direction of flow of current is always opposite the direction of the flow of electrons. Assuming that the electrons move in negative direction then the current will flow in the positive direction.

kepler used the data from tycho blahe (his mentor) to construct the laws of planetary motion.

you'd use the equation that establishes a relationship between  energy  and  wavelength, which looks like this

e=h⋅cλ, where

λ  - the wavelength of the photon; c  - the speed of light, usually given as  3⋅108m/s; h  -  planck's constant, equal to  6.626⋅10−34j s

plug the value you were given for the energy of the photon in the above equation to get the wavelength

e=h⋅cλ⇒λ=h⋅ce

λ=6.626⋅10−34js⋅3⋅108ms−1.257⋅10−24j=1.581⋅10−1m
