The electric currents and magnetic materials have an
effect called magnetic field. This magnetic field is specified with its
direction and magnitude. The magnitude is the strength of the field.
the magnetic field at a distance r from a
long straight wire carrying current I can be calculated with the
equation:
B = μ I / 2 pi R
where <span>μ is a constant, I is the current and R is the radius. </span>
Answer:
Length = 10
Width = 13
Step-by-step explanation:
If the width of a rectangle is 3 units less than the length and if the area is 130 square units, the length is 10 units and the width is 13 units.
Formula: A=wl
Therefore, you have to find what two numbers multiply together in order to recieve 130 units.
A=wl=13·10=130

<span>The aspect of geography that examines physical characteristics of the Earth is known as physical geography. The correct option among all the options that are given in the question is the third option or option "C".
Number of people in the year 2010 = 308.7 million
Number of people in the year 2000 = 281.4 million
Number of people by which the population grew = (308.7 - 281.4) million
= 27.3 million
Percentage of change in the population = (27.3/308.7) * 100
= 8.84 percent.
</span>
C
the correct answer would be c
