Answer:
Magnetic field at the center will be 
Explanation:
We have given that diameter of the loop d = 14 cm = 0.14 m
So radius 
Current in the loop i = 2.40
We know that magnetic field at center of circular loop is given by
So 
Magnetic field at the center will be
Answer:
There are a number of models as explained below.
Explanation:
- Depending on the position of the earth in the orbit, stars will be in different positions relative to the distant stars.
This model can be explained by the parallax effect. An object is viewed differently by the left and the right eye.
Reference can be made to the geocentric and heliocentric arguments. The first view argues that heavens are composed of 55 concentric spheres.
On the other hand, the heliocentric system, proposed by Copernicus, suggested that the Sun, not the earth, was the center of the solar system.
Coastal erosion has depleted a large portion of South Louisiana's wetlands along the coastline in swamps and marshes mainly due to storm surges. But other factors also contributed to this erosion. Canals and waterways dug through the marshes and swamps for the oil industry is one factor. Man-made levees erected to provide protection to residents living adjacent to the river is another major cause. Large scale logging especially in the early 1900's also damaged the wetlands.
Sometimes, you can play sport for a longer time than you should. You should always stop and take a little break and always drink water. Also, if something starts to hurt, stop, let someone responsible know and take a break.
Answer:
Option A. 11
Explanation:
The atomic number of an element does not change.
Recall:
Atomic number = proton number
If the atom is neutral, then,
Proton number = electron number
Since the element is sodium, then, the atomic number of sodium–25 is 11.
Also, we were told to obtain the electrons of a neutral atom of sodium–25
Therefore,
Atomic number = proton number = 11
Since the atom is neutral,
Proton number = electron number = 11
