Answer:
1.884 meters per second
Explanation:
s = d/t
d = C = 2πr = 2π(6) = 37.68 m
t = 20 s
s = (37.68 m)/(20 s)
s = 1.884 m/s
Answer:
456
Explanation:
impulse = Force x (time of contact)
this isn't really much information but hope this helps !: )
Answer:
One of Eight Planets : Earth
Spiral galaxy, One of the estimated billions of galaxies: Milky Way
Galaxy: Milky Way
Explanation:
According to the definition, appositive or apposition is a grammatical construction which represents similar noun phrases and nouns where one serves or defines the other one.
Here, the ultimate examples of apposition are mentioned in the given statement as Earth: One of Eight Planets, Milky Way: Spiral Galaxy and one of the estimated billions of galaxies: Milky Way.
With such kinds of words, it's easier to understand the noun or renames with a short definition written as a phrase.
Answer: Option (E) is the correct answer.
Explanation:
Latent heat is defined as the amount of heat required by per mole of a substance in order to change its state.
And, latent heat of freezing (fusion) is defined as the energy required for the phase change between a liquid and a solid without any change in their temperature.
Therefore, at zero degrees Celsius energy absorbed by the ice will be consumed in breaking the bond between the water molecules held together in the solid state.
Thus, we can conclude that when a block of ice at zero degrees Celsius melts, the ice absorbs energy but does not change its temperature.
Correct answer choice is :
A) From A to B is known as the wavelength and changing the pitch of the note will change its length.
Explanation:
The amount or quantity of period within two things, points, lines, etc. the state or fact of existing separate in space, as of one thing from another; remoteness. a linear amount of space: Seven miles is a distance too great to walk in an hour. Distance is a scalar quantity describing the interval in two points. It is just the measure of the interval.
