Answer:
n = 1,732 the amplitude must be increased by a factor of 1,732
Explanation:
The power delivered by a wave is given by
P = E / t
P = ½ μ w² v A²
let's apply this expression to our case the power tripled
3P₀ = ½ μ w² v A’²
let's write the amplitude function of a initial amplitude
A ’= n A₀
where n is a number
3 P₀ = (½ μy w² v A₀²) n²
3P₀ = P₀ n²
n = √ 3
n = 1,732
therefore the amplitude must be increased by a factor of 1,732
Let north and east be posetive
Y=20sin20

X=20cos20
18.79385243 west
Net horizontal components=60+(-18.79)
=41.20614758m
Net vertical=-6.84040267
X^2=41.20614758^2+(-6.684040267)^2
√x^2 =√1744.73771m
x=41.77m
Answer:

Explanation:
it needs excess heat except mercury and lithium.
Answer:
0.459 Tesla
Explanation:
Faraday's law:

Φ= NAB
V = N Δ (BA) /Δt
the change in BA
was: BA = 0 because initially B was zero.
V=IR
IR = N B A /Δt
q / Δt ×R = N B A / Δt
Or: B = q R / NA = 8.87 x 10^-3 × 45.0 / 1850×4.7 x 10^-4 =
= 0.459 Tesla
