Answer:
A
Explanation:
An antifreeze is a substance which when added to a liquid reduces the freezing point of the liquid. Hence the solution can only freeze at a lower temperature compared to the solvent. Examples of antifreeze includes salt and propylene glycol. Antifreeze are used in low temperature environments to prevent water from freezing quicky. Hence the answer is A.

Answer:
Option E
Explanation:
Red Dwarfs are abundant throughout the universe. They are stable and considered to be candidates for exoplanets capable of sustaining life.
White Dwarfs are stars in the last phase of their evolution. A red giant of under 10 solar masses that has used its critical elements will shed its outer layers, stats to collapse under its own gravity and shrink to a white dwarf. They longer experience nuclear fusion.
The two bodies we are most interested in are Giants and Supergiants but it is important to look at others.
Neutron Stars are collapsed giants that had an original mass many times that of the Sun and explode as a supernova leaving a neutron star. These stars are compressed so much that they are composed entirely of neutrons, parts of the atom without electrical charge. This is the equivalent of the size of the Sun in the same area as a city or the human population on Earth fitting inside an area the size of a sugar cube.
Wave speed = frequency * wavelength
We need to rearrange this equation because we are finding the wavelength :
Wavelength = wave speed / frequency
To rearrange it, I just divided it by frequency so that wavelength was the subject.
Now, input these numbers into this equation :
Wavelength = wave speed / frequency
Wavelength = 25 / 5
Wavelength = 5m
I think it would be a hill as you would gather momentum going down it, therefore causing acceleration.
Vector quantites: it is a quantity which has both direction and magnitude.
for example. force which has direction and magnitude both.
scalar quantities: it is a quantity which has magnitude only.
for example. age it has only magnitude.
