Answer: Part 1: Propellant Fraction (MR) = 8.76
Part 2: Propellant Fraction (MR) = 1.63
Explanation: The Ideal Rocket Equation is given by:
Δv = 
Where:
is relationship between exhaust velocity and specific impulse
is the porpellant fraction, also written as MR.
The relationship
is: 
To determine the fraction:
Δv = 

Knowing that change in velocity is Δv = 9.6km/s and
= 9.81m/s²
<u>Note:</u> Velocity and gravity have different measures, so to cancel them out, transform km in m by multiplying velocity by 10³.

<u>Part 1</u>: Isp = 450s

ln(MR) = 
ln (MR) = 2.17
MR = 
MR = 8.76
<u>Part 2:</u> Isp = 2000s

ln (MR) = 
ln (MR) = 0.49
MR = 
MR = 1.63
Answer:
Frequency (f) can be defined as the number of waves or crests or number of troughs that pass a point per unit second. It can be measured in Hertz (Hz) or 1/s.
Answer:
Explanation:
alleles are the different form of certain gene, and for each gene, you have two alleles, one from each parent. For example, you have two alleles for your eye color, let's say a brown allele and a blue allele (genotype Bb) but your physical appearance would be brown eyes (phentotype)
It allows people to see around the corner and anticipate what speed changes they will need to make
