Basically, they just allow us to see farther into space, therefore letting us see in closer detail what objects in space are made of, such as flaming balls of gas (stars).
(1) a beta particle is your answer. Na-24 decays through beta decay, turning a neutron into a proton, electron (beta particle), and an neutrino.
Answer: 54 atm
Explanation:
I did 67/82.5 then got 0.8121212121. I them divided 44 by 0.81212121 and got 54.1791044776
Answer is: <span>1.0×10</span>¹⁶.<span>
</span>P (power of laser) = 3,2 mW = 0,0032 W.
λ (wavelength) = 633 nm = 633 · 10⁻⁹m = 6,33·10⁻⁷m.
P = n·h·c÷λ ⇒ n = n=P·<span>λ/h</span>·<span>c.
</span>c -<span> speed of light </span><span>3⋅10</span>⁸ <span>m/s.
h - </span><span>Planck's constant - </span><span>6.63⋅10</span>⁻³⁴J·<span>s.
n - number of photons emited.
n = 0,0032W </span>· 6,33·10⁻⁷m / 6.63⋅10⁻³⁴J·s · 3⋅10⁸ m/s
n = 1·10¹⁶ 1/s.<span>
