Answer:
1. Who gathered the data that showed planets traveling in elliptical paths around the sun?
2. Who discovered elliptical orbits?
3. Who explained them?
Explanation:
1. Tycho Brahe was the one that gathered data.
2. Johannes Kepler discovered it using Tycho Brace’s Data.
3. I believe it was Johannes Kepler because he created 3 laws of it.
I apologize if it is incorrect-
I hope it helps! Have a great day!

Answer: As a red photon has a twice of the wavelegth to the violet photon then the red photon has half energy of the violet photon.
Explanation: In order to explain the above statement we have to consider the Plack postulate where the energy of photons depend directely of the frequency . As the wavelength and frequency are related by :
c= λ*υ c is the speed of light, λ is the wavelength and υ the frequency of the photon
so the energy of photons are inversely proportional to the wavelength.
As a consequence twice wavelengtht means half energy for the photon.
Answer:
light scattering by particles in a colloid or in a very fine suspension
Explanation:
It is given that,
Speed of the ball, v = 10 m/s
Initial position of ball above ground, h = 20 m
(a) Let H is the maximum height reached by the ball. It can be calculated using the conservation of energy as :
h' = 5.1 m
The maximum height above ground,
H = 5.1 + 20
H = 25.1 meters
So, the maximum height reached by the ball is 25.1 meters.
(b) The ball's speed as it passes the window on its way down is same as the initial speed i.e. 10 m/s.
Hence, this is the required solution.
