Answer:
Explanation:
one leg is 6 inches, other leg is 6√3 inches.
By the diagram
the third side = 
let the angle is α
α = 35.3°
Answer:
V = 8.34m/s
Explanation:
Given that
1/2ke^2 = 1/2mv^2 ......1
Where e = 3.75cm = (3.75/100)m
e = 0.0375m
K = 500 N/m
m = 10g = 10/1000
= 0.01kg
Substitute the values into equation 1
0.5×500×(0.0375)^2 = 0.5×0.01×v^2
250×0.001395 = 0.005v^2
0.348 = 0.005v^2
v^2 = 0.348/0.005
v^2 = 69.6
V = √69.6
V = 8.34m/s
The ball launches at the speed of V = 8.34m/s
Answer:
Because they are moving to fast for Earth's gravity to pull it down.
<span>So we want to know what does the wavelength of vidible light corresponds to. So the wavelength of visible light is around 400 - 700 nm or 400*10^-9 m to 700*10^-9 m. Virus size is around 20 - 400 nm. Large moleculer are around 100 nm to 200 nm. Atoms are around 10^-10 m and all the other options are too large. So the correct answer is B. </span>

I think the limitation is that the electrons in the Bohr model are only in certain energy levels and that they orbit the nucleus.
It's been a while since I was in a physical science class so I'm not sure about the rest but I wish you luck! I hope this helps a little bit!
