Answer:
Explanation:
<em>Assuming the triangle is a right triangle,</em>
the magnitude of R can be found using the Pythagorean theorem,
R = sqrt(9.7^2+6^2) = 11.41 m
The angle can be found by arctangent, which is
angle = atan(9.7/6) = 58.26 degrees.
Answer:
Explanation:
The formula for hydrogen atomic spectrum is as follows
energy of photon due to transition from higher orbit n₂ to n₁

For layman series n₁ = 1 and n₂ = 2 , 3 , 4 , ... etc
energy of first line

10.2 eV
wavelength of photon = 12375 / 10.2 = 1213.2 A
energy of 2 nd line

= 12.08 eV
wavelength of photon = 12375 / 12.08 = 1024.4 A
energy of third line

12.75 e V
wavelength of photon = 12375 / 12.75 = 970.6 A
energy of fourth line

= 13.056 eV
wavelength of photon = 12375 / 13.05 = 948.3 A
energy of fifth line

13.22 eV
wavelength of photon = 12375 / 13.22 = 936.1 A
Well first of all, a planet doesn't have a semimajor axis, although it's orbit does.
In an orbit with a smaller semimajor axis, the planet moves faster, and its orbital period is shorter.
That's why the International Space Station circles the Earth in less time than the Moon does.
