Formula for calculating [Average Atomic Mass] of Pb (Lead):AAM of [element] = (Mass of isotope) * (Relative abundance) and you can repeat the "(Mass of isotope) * (Relative abundance)" part for each isotope! Therefore...AAM of Pb=(203.97302)(0.014)+(205.97444)(0.241)+(206.97587)(0.221)+(207.97663)(0.524)AAM of Pb = 207.21688371 amu [OR] 207.2 amu on most periodic tables.
Well, they have the same speed when they're in the
same medium, and they both have the same physical
nature, since they're all electromagnetic radiation.
Fascinating factoid:
Many point-to-point radio systems use AM and FM at the same time
on the same signal, in order to carry more information on the signal.
Answer:
5.76 μC
Explanation:
The induce emf, ε = -ΔΦ/Δt where ΔΦ = change in magnetic flux = NAΔB where N = number of turns of coil = 1000, A = cross-sectional area of coil = πd²/4 where d = diameter of coil = 2 cm = 2 × 10⁻² m and ΔB = change in magnetic field strength = B' - B where B' = final magnetic field = 0 T and B = initial magnetic field strength = 0.011 T. So, ΔB = 0 T - 0.011 T = -0.011 T
So, ε = -ΔΦ/Δt
ε = -NAΔB/Δt
ε = -NAΔB/Δt
Also ε = iR where i = current and R = combined resistance of circular coil and galvanometer = 200 Ω + 400 Ω = 600 Ω (since they are in series)
So, iR = -NAΔB/Δt
iΔt = -NAΔB/R
Δq = -NAΔB/R where Δq = charge = iΔt
substituting the values of the variables into the equation, we have
Δq = -1000 × π(2 × 10⁻² m)²/4 × -0.011 T/600 Ω
Δq = -1000 × 4π × 10⁻⁴ m²/4 × -0.011 T/600 Ω
Δq = 0.011π × 10⁻¹ m²T/600 Ω
Δq = 0.03456 × 10⁻¹ m²T/600 Ω
Δq = 5.76 × 10⁻⁶ C
Δq = 5.76 μC
Answer:
Reverse Flash
Explanation:
the Reverse Flash is obviously faster than the Flash. He is more experienced and much stronger . And unlike Berry he is not affected by time travel
Answer:
A)
Explanation:
The lowest latitudes get the most energy from the sun. The highest latitudes get the least.
