Answer: lambda 
, nu 
, and 100E
Explanation:
The energy 
of a photon is given by:
(1)
Where:
is the Planck constant
is the frequency
On the other hand, we have an expression that relates the frequency of the photn with its wavelength :
(2) where 
is the speed of light
Substituting (2) in (1):
(3) This is the energy for a single photon
For 100 photons, the energy is:
(3)
Where the wavelength and the frequency of the light remains constant.
Therefore, the answer is:
, , and 100E
Magma is a molten and semi-molten rock mixture found under the surface of the earth. and i think silica is the most abundant. hope it helps.sorry if it's uncorrect. :)
Answer:
Only a decreasing gravitational force that acts downward
Explanation:
The gravitational force is the gravitational pull which attract a mass of smaller size by the mass of a bigger size. It is the force which attract two masses close to each other.
In the context, when a ball is tossed up from the surface of an asteroid that have no atmosphere, the ball rises up and then falls back to the surface of the asteroid. The ball falls back because the gravitational pull of the asteroid pulls back the ball to its surface. Thus a decreasing gravitational force acts on the ball in the downward direction while the ball is in its way up.
Weak base i think since it’s a lower ph
