Without any confirmation it will be utterly wrong to conclude that high power voltage is the reason for the elevated cancer cases
Therefore
Option B
b)
The High Concentration of cells volume in a part of the Body is what causes Cancer
Therefore
Option B
So the first thing you need to do is convert the wavelength from centimeters to meters. This is quite easy, all you do is divide by 100.
Then I'm assuming the equation they're talking about is c = f λ.
c = the speed of the wave
f = the frequency of the wave
<span>λ = the wavelength
</span>
So all you need to do is multiply the frequency they gave you by the wavelength you calculated.
TOP ROW
f = 10 hz
<span>λ = .1 m
</span>c = 10×.1
c = 1 m/s
2ND ROW
<span>f = 2.5 hz
</span><span>λ = 10</span>÷100
λ = .1 m
c = 2.5×.1
c = .25 m/s
3RD ROW
f = 30 hz
λ = 2÷100
<span>λ = .02
</span>c = 30×.02
c = .6 m/s
BOTTOM ROW
f = 50 hz
<span>λ = 1</span>÷100<span>
</span><span>λ = .01
</span>c = 50×.01
c = .5 m/s
y = 0m
y0 = 166m
v0y = 0 m/s
g = 9.8 m/s^2
t = ?
Solve for t:
y = y0 + v0y*t - (0.5)gt^2
0 = 166 - (0.5)(9.8)t^2
t = 5.82 s
Now, using time, we can solve for the range using the equation:
x = vx(t)
x = (40)(5.82)
x = 232.8 m
The impact horizontal component of velocity will be 40 m/s as velocity in terms of x is always constant. To find the impact vertical component of velocity, we use the equation:
v = v0y - gt
v = 0 - (9.8)(5.82)
v = -57.04 m/s
In a closed system, energy in form of heat (work) can be exchanged but not matter.
The answer to your question is C.
Hope it helped!
That would be c. :) :) :)
