Explanation:
The density of the magnetic flux is given by the following formula:
The normal vector A and the vector of the magnitude of the magnetic field are perpendicular, then, the angle is zero:
The magnitude of the magnetic field is calculated by using the formula for B at a distance of x to a point in the plane of the loop:
For x = 0 you have:
R is the radius of the circular loop and its values is:
Then, you replace in the equation for B with mu_o = 4\pi*10^-7 T/A:
and the density of the magnetic flux is
Answer:
Surface waves are the kind of waves that occur on the surface of the ocean. The reason behind their occurrence is the geological effects, usually in the form of winds in near geographical regions or in that region.
These waves reach the land when the geological winds give a push to the waves and they travel miles and finally hit the land. These waves range in sizes, for small sizes to the the size of tsunami.
<span>The Solar electricity source of
energy comes from the sun’s rays. It is more often in the form of a panel known
as the solar panel. It has a photovoltaic system that generates and supplies
energy in commercial and residential areas. Even though numerous countries are
using this type of electricity to save electric-induced power, it is not used
for a number of reasons. One is that 1 panel with a size of 6 by 10 solar cells
is expensive. There are countries who cannot afford to buy them. Two, it
requires a larger area to place the panel. Three, the efficiency is low. The smaller
the panel is, the lower its efficiency and therefore produces lesser power to
generate a specific area. </span>
Answer:
p = 0.16 kgm/s
Explanation:
the initial momentum combined of the two cars and the final momentum of the paired cares are the same, so we just need to find the initial momentum
p = m1v1 + m2v2
p = 0.04*4 + 0.04*0
p = 0.04*4
p = 0.16 kgm/s
