Answer:
14 billion years
Explanation:
The Hubble – Lemaître law, previously called the Hubble law, is a law of physics that states that the redshift of a galaxy is proportional to the distance it is, which is the same as, the further one galaxy is found from another, more quickly it seems to move away from it.
The Hubble constant is the value that measures the rate at which the expansion speed of the Universe varies with distance, and is one of the fundamental parameters of the Universe and allows, in particular, to determine the age of the Universe as we will see.
To solve for distance use the formula for distance d = st, or distance equals speed times time.
distance = speed x timeSpeed
so the answer is 240 miles per hour.
Answer: Solor cycles and tings
Answer:
False: Quaternary structure is achieved when multiple polypeptide chains in protein come together.
Explanation:
There are four levels of protein structure: primary, secondary, tertiary, and Quaternary structure.
Tertiary structure is a protein structure, which is achieved when a protein folds into a compact, three-dimensional shape stabilized by interactions between side-chain R groups of amino acids.
However, Quaternary structure is achieved when multiple polypeptide chains in protein come together.
Answer: The Propellant fraction is 0.87.
The payload fraction is 0.04.
Δv = 8991.81 m/s
Explanation: To determine the fractions, first, calculate the total mass of the rocket:
The Propellant Fraction will be
0.87
The Payload Fraction is:
0.04
The value of Δv is calculated by the formula:
Δv = 
The exhaust velocity (
) is:
9.81*450
4414.5
is the total mass after the rocket consume all the propellant and 
is the total mass before the action.
Δv =
Δv = 
Δv = - 4414.5.ln(0.13)
Δv = 8991.81
Δv will be 8991.81 m/s.
