Answer: To solve for the net magnetic field of two circular loops of wire, each containing a single turn
B net= √[( NUI / 2R)^2 × ( NUI / 2R)^2]
Where B net = Net magnetic field
B net = √2 × (NUI/ 2R)
B net =[ √2 × 1 × ( 4 × 3.142 × 10^-7) × (1.8)] ÷ 2 × 0.034
B net = { 1.414 × (0.00000126) × (1.8)}÷ 0.068
B net = 4.72 × 10^-5 T
Yes the Earth is bigger than the Moon.
The moon is one-quarter the size of Earth.
Answer:
Measurements refers to a process which typically involves identifying and determining the dimensions of a physical object.
Explanation:
A scientific method can be defined as a research method that typically involves the use of experimental and mathematical techniques which comprises of a series of steps such as systematic observation, measurement, and analysis to formulate, test and modify a hypothesis.
Measurements refers to a process which typically involves identifying and determining the dimensions of a physical object.
Basically, the dimensions include important parameters such as width, height, length, area, volume, circumference, breadth, etc.
