Answer:
Absorption Spectrum
Explanation:
The hot, dense source emits high energy photons of all wavelengths. Some of these photons are absorbed by electrons of cloud to excite them to a higher energy level which appear as dark lines in the spectra and we get Absorption Spectrum.
Answer:
511.545 Newtons
Explanation:
So 1 pound=4.44822 Newton’s so 115 times 4.44822 is 511.5453, then round it to get 511.545 Newtons.
Answer:9.82 m
Explanation:
As we know from equation of motion
S=v*t +0.5 a t^2
Know s=H/2
a =9.82
t=1
V=0
Plugging the values
H*0.5=0+0.5*9.82*1^2
H=9.82 m
<em>≈ 0.47 m/s²</em>
<em>Hi there !</em>
<em>Acceleration formula</em>
<em>a = (v₂ - v₁)/t</em>
<em />
<em>a = (26.8m/s - 24.8m/s)/4.3s</em>
<em>= (2m/s)/4.3s</em>
<em>≈ 0.47 m/s²</em>
<em>Good luck !</em>
