1/5 of the atmosphere is NOT made of nitrogen
<u>Answer:</u>
The wavelength of the photon nathan would have to absorb if he wanted to jump from levels 2 to 4 = 296.53 nm
<u>Explanation:</u>
The energy of the absorbed photon can be found using, , where is the initial quantum level and is the final quantum level.
And we also have E =hc/λ , where h is Planck's constant, c is the speed of light and λ is the wavelength of photon absorbed.
So E is inversely proportional to λ and E is directly proportional to
So λ is inversely proportional to
We have
So the wavelength of the photon nathan would have to absorb if he wanted to jump from levels 2 to 4 = 296.53 nm
Answer:
The force that cause the centripetal acceleration is the static friction, and the briefcase begin to move if the force of centripetal acceleration exceeds the force due to the static friction
Explanation:
Given data:
r = radius = 54.5 m
v = speed of the car = 12.4 m/s
The force due to the static friction that is exerted on the curve in the road is what causes the centripetal acceleration. If the force due to centripetal acceleration is greater than the force of static friction, then the briefcase will begin to roll.
Oil must be mined from underground.
Answer:
Such a bond forms when the valence (outermost) electrons of one atom are transferred permanently to another atom. ... The atom that loses the electrons becomes a positively charged ion (cation), while the one that gains them becomes a negatively charged ion (anion). A brief treatment of ionic bonds follows.
Explanation:
