Answer: Two marbles separated by 300 kilometers
Explanation: Hope i helped have a great day and please mark brainliest i would appreciate it!
The light gathering of a telescope goes as the area of the telescope, therefore as the square of the aperture:
where D is the aperture of the telescope.
Therefore, using D1=8 m and D2=2 m, we find
So, the larger telescope will collect 16 times more light than the smaller one.
Sherry who says one factor is the length of the path of sunlight is correct.
<h3>
Factors affecting light scattering</h3>
There are two main factors which affects light scattering, and they include the following;
- the size of the particles
- wavelength of the light
length of the path of sunlight is equivalent to wavelength of the light.
Thus, we can conclude that Sherry who says one factor is the length of the path of sunlight is correct.

Density’s is mass by volume
So mass is 48 grams
Volume is 8cm^3
There is no need to convert units as they are same
So 48/8 gives you 6
So your answe should be 6g/cm^3 or 6gcm^-3
Answer:
175s
Explanation:
time it takes sunlight to reach the earth in vacuum
C=light speed=299792458m/s
X=1.5x10^8km=1.5x10^11m
c=X/t
T1=X/c
T1=1.5X10^11/299792458=500.34s
time it takes sunlight to reach the earth in water:
First we calculate the speed of light in water taking into account the refractive index
Cw=299792458m/s/1.349=222233104.5m/s
T2=1.5x10^11/222233104.5m/s=675s
additional time it would take for the light to reach the earth
ΔT=T2-T1=675-500=175s
