Explanation:
Answer:
a) red wave hs a longer wavelength than the green wave
b)f = 1.875 10¹¹ Hz
, f_green = 5.45 10¹⁴Hz
c) E = 1.24 10⁻²² J
, E_green = 3.6 10⁻¹⁹ J
d) The red wave is in the infrared range, heat waves
The green wave is in the visible wavelength
Explanation:
a) The green wave are on the left in the electromagnetic spectrum so the red wave has a longer wavelength than the green wave
The green wavelength is in the range of 550 10⁻⁹ m
The speed of the wave is
c = λ f
f = c /λ
b) The frequency of the red wave is
f = 3 10⁸ / 1.6 10⁻³
f = 1.875 10¹¹ Hz
For the green wave
f_green = 3 10⁸/550 10⁻⁹
f_green = 5.45 10¹⁴Hz
c) The photon energy is given by the Planck equation
E = h f
E = 6.63 10⁻³⁴ 1.875 10¹¹
E = 1.24 10⁻²² J
For the green wave
E_green = 6.63 10⁻³⁴ 5.45 10¹⁴
E_green = 3.6 10⁻¹⁹ J
d) The speed of electromagnetic waves is constant and has a value of 3 108 m / s
e)
The red wave is in the infrared range, heat waves
The green wave is in the visible wavelength
(a) At a corresponding hill on Earth and a lesser gravity on planet Epslion, the height of the hill will cause a reduction in the initial speed of the snowboarder from 4 m/s to a value greater than zero (0).
(b) If the initial speed at the bottom of the hill is 5 m/s, the final speed at the top of the hill be greater than 3 m/s.
<h3>
Conservation of mechanical energy</h3>
The effect of height and gravity on speed on the given planet Epislon is determined by applying the principle of conservation of mechanical energy as shown below;
ΔK.E = ΔP.E
¹/₂m(v²- u²) = mg(hi - hf)
¹/₂(v²- u²) = g(0 - hf)
v² - u² = -2ghf
v² = u² - 2ghf
where;
- v is the final velocity at upper level
- u is the initial velocity
- hf is final height
- g is acceleration due to gravity
when u² = 2gh, then v² = 0,
when gravity reduces, u² > 2gh, and v² > 0
Thus, at a corresponding hill on Earth and a lesser gravity on planet Epslion, the height of the hill will cause a reduction in the initial speed of the snowboarder from 4 m/s to a value greater than zero (0).
<h3>Final speed</h3>
v² = u² - 2ghf
where;
- u is the initial speed = 5 m/s
- g is acceleration due to gravity and its less than 9.8 m/s²
- v is final speed
- hf is equal height
Since g on Epislon is less than 9.8 m/s² of Earth;
5² - 2ghf > 3 m/s
Thus, if the initial speed at the bottom of the hill is 5 m/s, the final speed at the top of the hill be greater than 3 m/s.

Hello.
The gaseous state is the more compressible state, because it has the volume of its container.
The liquid state is virtually incompressible, and the solid state compression is very small.
The plasma is another state that has high compression, but in this case the matter is not bound(we don't have the proton in the core of the atom)
I don't know what the exact word is, but I do know that the bigger an objects mass is the more it will attract other objects toward it, mainly smaller objects with less mass. it might be gravity or something around those lines....is it a multiple choice question?
