Answer:
Explanation:
Fractional distillation is the separation of a mixture into its component parts, or fractions. Chemical compounds are separated by heating them to a temperature at which one or more fractions of the mixture will vaporize. It uses distillation to fractionate
it is the separation of a liquid mixture into fractions differing in boiling point (and hence chemical composition) by means of distillation, typically using a fractionating column.
cracking allows large hydrocarbon molecules to be broken down into smaller, more useful hydrocarbon molecules. Fractions containing large hydrocarbon molecules are heated to vaporise them. They are then either: heated to 600-700°C.

Answer:
The original length of the specimen is found to be 76.093 mm.
Explanation:
From the conservation of mass principal, we know that the volume of the specimen must remain constant. Therefore, comparing the volumes of both initial and final state as state 1 and state 2:
Initial Volume = Final Volume
πd1²L1/4 = πd2²L2/4
d1²L1 = d2²L2
L1 = d2²L2/d1²
where,
d1 = initial diameter = 19.636 mm
d2 = final diameter = 19.661 mm
L1 = Initial Length = Original Length = ?
L2 = Final Length = 75.9 mm
Therefore, using values:
L1 = (19.661 mm)²(75.9 mm)/(19.636 mm)²
<u>L1 = 76.093 mm</u>
Technician a. Components should always look the same so they are known universally
Answer:
a) s = 42 m
b) V = 26 m/s
c) a = 11 m/s²
Explanation:
The velocity(V) = 2 - 4t + 5t^3/2 where t is in seconds and V is in m/s
a) To get the position, we have to integrate the velocity with respect to time.
We get the position(s) from the equation:
Integrating both sides,
Integrating, we get
But at t=0, s(0) = 2 m
Therefore,
c = 2
Therefore
When t = 4,
s = 42 m
At t= 4s, the position s = 42m
b) The velocity equation is given by:
At t = 4,
V = 2 - 16 + 40 = 26 m/s
The velocity(V)at t = 4 s is 26 m/s
c) The acceleration(a) is given by:
Differentiating with respect to t,
At t = 4 s,
a = 11 m/s²
