0.75 km = (0.75×100000) cm = 75000 cm
The scientific notation to find this is ---
Kilo-Hecto-Deca-Meter-Deci-Centi-Milli
Answer:
The outward current must be 5.0 A
Explanation:
-A junction is a point where at least three circuit paths meet.
-According to Kirchhoff's Junction Rule & the Law of Charge Conservation:
-The outward current must always equal the inward current because charge is conserved and current measures the rate at which charges are flowing.
Ek = 1/2mv^2
Ek = 1/2 * 30kg * 20^2 m/s
Ek = 6000J
Hope this Helps!
Answer:
phase difference = π / 2
constructive interference
Explanation:
Given data
wavelength = 420 nm
1st beam = 105 nm
path difference = 105 nm
to find out
phase difference and interference pattern of the two beams
solution
we use here equation of phase difference that is
phase difference = 2π / wavelength × Δx
put here value
phase difference = 2π / 420 × 105
phase difference = π / 2
and
we know that here path difference Δx is the integral multiple of the wavelength so it will be constructive interference
Δx is wavelength / 4
