Answer:
Magnetic field experienced = 4.5 × 10⁻⁴ T
Explanation:
The magnetic field around an infinite straight current-carrying wire at a distance r from the wire is given by
B = (μ₀I)/(2πr)
B = ?
I = 20 KA = 20000 A
r = 8.9 m
μ₀ = magnetic permeability = 1.257 × 10⁻⁶ T.m/A
B = (1.257 × 10⁻⁶ × 20000)/(2π×8.9) = 4.5 × 10⁻⁴ T
My Answer: They contain a high diversity of organisms.
Hope I helped! :D
Answer:
Friction always acts to oppose any relative motion between surfaces. ... If we push on the book with a force of less than 5 N, the book won't move, because the frictional force will exactly balance the force we apply. If we push with a 1 N force, a 1 N frictional force opposes us.
Explanation:
none
1) The similarity is that in both the cases the light is deviated from its original path i.e. their angles change (even for a short while in a refraction) and the difference is in reflection the angle of incidence is equal to the angle of reflection whereas in refraction the angle of incidence is not equal to the angle of reflection.
2) A white t-shirt would feel cooler on a sunny day.
A black surface attracts heat and wearing a black t-shirt would attract the heat from the sun making us feel hotter.
3) There are three measurable properties
of wave motion: amplitude, wavelength,
and frequency. A definitive experiment was
Young's double slit experiment, which
demonstrated that light shined at two slits
in a screen show an interference pattern
characteristic of waves of light, rather than
particles.
