A long straight wire carries a 40.0 A current in the +x direction. At a particular instant, an electron moving at 1.0  107 m/s

in the +y direction is 0.10 m from the wire. The charge on the electron is –1.6  10–19 C. What is the force on the electron at this instant?

Answer:

F=-1.28\times 10^{-16}\ N

Explanation:

Given that,

Current flowing in the wire, I = 40 A (+x direction)

Speed of the electron, v=10^7\ m/s (+y direction)

Distance from the wire, r = 0.1 m

Let F is the electric force on the electron. It is given by :

F=qvB\ sin\theta

Here, \theta=90

F=qvB

Here, B=\dfrac{\mu_oI}{2\pi r}

F=qv\dfrac{\mu_oI}{2\pi r}

F=-1.6\times 10^{-19}\times 10^7\times \dfrac{4\pi\times 10^{-7}\times 40}{2\pi \times 0.1}

F=-1.28\times 10^{-16}\ N

So, the force on the electron at this instant is -1.28\times 10^{-16}\ N. Hence, this is the required solution.

Answer:

1) C. The precise location of weather-related phenomena

2) C. It shows that the galaxies are moving farther away.

Explanation:

1) The global positioning system can be used in many ways, like in navigation, mapping and surveying the land. It is also used to observe the small changes taking place in the movement of objects on earth. They are usually used to study earthquakes.

2) When light from the galaxies is shifted towards the longer wavelengths, it is called red shift. When light shifts towards the shorter wavelengths, it is called blue shift. Big bang theory states how the primordial universe started expanding from a hot and dense singularity, in the process of evolution of the universe.

The  universe is expanding always. Galaxies that are a part of the universe keep expanding and move farther away from each other. The galaxies that are very far off appear to  move much faster than the nearby galaxies.

The correct answer is:
<span>C: in the protons and neutrons of an atom

In fact, the nuclear energy refers to the binding energy of the nucleons (protons and neutrons) of an atom. The protons and the neutrons are held together by the strong nuclear interaction, one of the four fundamental forces of nature, and the energy associated to this interaction is called nuclear energy.

D) Kirchhoff’s junction rule states that at any junction, the sum of the altimeter attained moving into and out of that junction are equal.

While

Kirchhoff’s loop rule states that the algebraic sum of the number of lifts used in any closed loop is equal to zero

Explanation:

Given that the lifts are analogous to batteries, and the runs are analogous to resistors. 

So from all the figures. The resistors represent the runs while the lift represents the battery.

Kirchhoff’s junction rule states that at any junction, the sum of the altimeter attained moving into and out of that junction are equal.

While

Kirchhoff’s loop rule states that the algebraic sum of the number of lifts used in any closed loop is equal to zero
