Answer:
(a) B = 5.6 micro Tesla
Explanation:
Current in the wire, i = 140 A
distance, r = 5 m
The formula for the magnetic field at a distance r due to the current carrying wire
B = 5.6 x 10^-6 Tesla
B = 5.6 micro Tesla
(b) As the magnetic field of earth at this site is 20 micro tesla so the magnetic field due to current carrying wire interfere the magnetic compass.
Answer:
6.97 E 16
Explanation:
Frequency is a function of velocity of light to it's wavelength.
Mathematically written as
F = Velocity / wavelength
Velocity of light = 3 x 10^8
Wavelength =430 nm =430 x 10^-9 m
converting wavelength from nanaometer to meter we divide by 10^9
Frequency = (3 x 10^8)/(430 x10^-9) =6.97 E 16
It's the first one. Believe me I always missed this question in class, never is ask a question first. Hypothesis is first.
Answer:
Radiation is characterized as the Emission and propogation of Energy(atomic and subatomic particles) in the form of Electromegnetic (Electric and Magnetic lines) waves through space or any medium.
Explanation:
These radiation can be in the form of heat rays , light rays, Xrays or UV rays.
Radition is bascically flow or movement of atomic particles or particularly energy in different forms. It is usually transmitted from a source to the destination for transferring Energy.
