Answer:
Option A, World War II
Explanation:
During the period of industrial revolution around 1915-25, the chemical engineering has taken a new shape. During this period (i.e around the world war I), there was rise in demand for liquid fuels, synthetic fertilizer, and other chemical products. This lead to development of chemistry centre in Germany . There was rise in use of synthetics fibres and polymers. World war II saw the growth of catalytic cracking, fluidized beds, synthetic rubber, pharmaceuticals production, oil & oil products, etc. and because of rising chemical demand, chemical engineering took a new shape during this period
Hence, option A is the right answer

Question 4 (1 point) Sophia is working in her garden. She made two trips with her wagon along the same path to haul supplies. The first held 3 bags of soil, while the second load had 5 bags. Assuming they accelerated the same, which required more force to move. The one with 5 bags. The one with 3 bags. An equal amount of force is required for both. Neither will take any force because the wheels reduce friction.

Find the size of the resistor which would limit the current to a value of 2 mA when connected to an 8 V supply
Answer:
R = 4000 ohms
Explanation:
Given that,
Current, I = 2 mA
The voltage of the supply, V = 8 V
We need to find the resistance of the resistor. We know that, Ohm's law is as follows :
V = IR
Where
R is resistance
So,
[tex]R=\dfrac{V}{I}\\\\R=\dfrac{8}{2\times 10^{-3}}\\\\\\R=4000\ \Omega[/tex]
So, the resistance of the resistor is 4000 ohms.
