Answer:
D (density) = Mass / Volume
V (ice) = Mass / Density = 50000 g / .92 kg / L
V = 50 kg / .92 kg / L
1 Liter of water weighs 1 kilogram = 50 L weighs 50000 g
V = 54.3 L the mass does not change upon the change of phase (freezing)
Gregor Mendel is considered the "Father of Genetics" because of his work with pea plants.
The answer would be E7. Galaxies categorized as E0 look to
be nearly perfect, while those registered as E7 seem much extended than they
are widespread. It is worth noting, though, that a galaxy's look is connected
to how it lies on the sky when viewed from Earth. An E7 galaxy is very long and
thin or the flattest of them all.
Answer:

Explanation:
Since the field lines are parallel and the electric field is uniform between two parallel plates, a test charge would experience the same force of attraction or repulsion no matter where it is located in the field,
I attached an image that could help to understand the representation of the field. The formula used to calculate it is given by,
(1)
If we want to consider the change in Voltage with respect to the position then it would be,

According to the information provided, the potential is
and there is a distance d, therefore
(2)
Taking equation (1) we can clear V, to what we have,


Integrating,

Substituting (2)


Where x is the height from the grounded plate.
The sound absorption for wood is greater than the sound absorption coeffiecient for concrete at most frequencies, hence based on the coefficient of absorption for each material, wood is the best choice.
