Answer:
1 - amplification
3- actinide
5 - radioactive decay ( im not really sure on this one )
7- alternating current
Explanation:
Iron rich minerals in rock pointed in one direction the switch to the exact opposite direction. I'd say that what supports this idea is that Earth's magnetic field goes through pole reversals.<span>

Answer:
ΔE = 1.031 eV
Explanation:
For this exercise let's calculate the energy of the photons using Planck's equation
E = h f
wavelength and frequency are related
c = λ f
f = c /λ
let's substitute
E = h c /λ
let's calculate
E = 6.63 10⁻³⁴ 3 10⁸/1064 10⁻⁹
E = 1.869 10⁻¹⁹ J
let's reduce to eV
E = 1.869 10⁻¹⁹ J (1 eV / 1.6 10⁻¹⁹ J)
E = 1.168 eV
therefore the electron affinity is
ΔE = E - 0.137
ΔE = 1.168 - 0.137
ΔE = 1.031 eV
Water at the top of Horseshoe Falls (part of Niagara Falls) is moving horizontally at 9.2 m/s, the angle with respect to the vertical is mathematically given as
<h3>What angle with respect to the
vertical is the falling water moving as it enters the pool?</h3>
Generally, the equation for velocity is mathematically given as
V^2=u^2+2as
Therefore
V^{2}=0+2(9.81)(53)
V=32.2m/s
In conclusion, The angle
