Explanation:
During the Second World War, she oversaw the design of production plants for the strategically important materials of penicillin and synthetic rubber.Her development of deep-tank fermentation of penicillium mold enabled large-scale production of penicillin.She worked on the development of high-octane gasoline for aviation fuel.Her later work included improved distillation column design and plants for the production of ethylene glycol and glacial acetic acid.
Answer:
For small temperature difference between a body and its surrounding, the rate of cooling of the body is directly proportional to the temperature difference and the surface area exposed. qf = final temperature of object

Explanation:
See attachment for the detailed step by step solution of the given problem.
Answer:
1) A=282.6 mm
2)
3)T=0.42 sec
4)f= 2.24 Hz
Explanation:
Given that
V=3.5 m/s at x=150 mm ------------1
V=2.5 m/s at x=225 mm ------------2
Where x measured from mid position.
We know that velocity in simple harmonic given as

Where A is the amplitude and ω is the natural frequency of simple harmonic motion.
From equation 1 and 2
------3
--------4
Now by dividing equation 3 by 4


So A=0.2826 m
A=282.6 mm
Now by putting the values of A in the equation 3


ω=14.609 rad/s
Frequency
ω= 2πf
14.609= 2 x π x f
f= 2.24 Hz
Maximum acceleration



Time period T


T=0.42 sec
