(a) The gas of interstellar medium can be detected from the radiations of photons of wavelength 21 cm.
(b) The gas of interstellar medium can be detected from the absorption lines present in the light from distant stars, which must be caused by a medium of density and temperature other than that of the stars emitting the lights.
<h3>
What is interstellar medium?</h3>
Interstellar medium is the matter and radiation that exist in the space between the star systems in a galaxy.
<h3>Evidence that interstellar medium contains both gas and dust</h3>
- The gas of interstellar medium can be detected from the radiations of photons of wavelength 21 cm.
- The gas of interstellar medium can be detected from the absorption lines present in the light from distant stars, which must be caused by a medium of density and temperature other than that of the stars emitting the lights.

The photosystem channels the excitation energy gathered by absorption of light by any one of the pigment molecules to a specific "reaction center chlorophyll," which in turn passes the energy to
-photosystem I.
-photosystem II.
-the primary electron acceptor.
-the secondary electron center.
-cytochrome.
Answer: -the primary electron acceptor.
Explanation:
The photosystem II has a reaction center, in the reaction center the energy from sunlight is converted into high energy electrons. At the center of the reaction center, chlorophyll molecule is present which absorbs the light and one of its electron is promoted to the higher energy.
The high energy electron is hop downward and it is transferred to the plastoquinone A, which is a primary electron acceptor. Then the electron is transferred to the plastoquinone B. The plastoquinone B will receives enough electrons it delivers its electron to the electron transfer chain.
Answer:
Well AM/Fm is digitally using soundwaves for cars through signal, which we cant hear without one (radio). Concerts are in real life and use wavelegnths that we hear because it bounces off overytihing.
Explanation:
Answer:
I dont really know much but i know that it swallow anything it comes across in space.
The first time we read this, we think that we'll have to go look up a bunch of stuff about the gravitational constant, centripetal force, orbital mechanics, the Moon's period of revolution, and who knows whut owl !
But you know whut ? The only thing we need is Newton's 2nd law:
F = m A
Divide each side by m :
Acceleration = Force / mass
Acceleration = (2.03 x 10²⁰ Newtons) / (7.35 x 10²² kg)
Acceleration = (2.03 x 10²⁰ / 7.35 x 10²² kg) (m/s²)
<em>Acceleration = 0.00276 m/s²</em>
