Answer:
Amount of fuel used per year is supposed to be 34150 KJ/kg
Your minimum selling price must be HIGHER THAN your variable costs
Answer:
222.5 Gpa
Explanation:
From definition of engineering stress, 
where F is applied force and A is original area
Also, engineering strain,
where l is original area and
is elongation
We also know that Hooke's law states that 
Since A=20 mm* 20 mm= 0.02 m*0.02 m
F= 89000 N
l= 100 mm= 0.1 m

By substitution we obtain

Answer:
16-bit wide
Explanation:
In order to find the width of the address bus, we need first to know how many memory cells it is needed to address.
If the size memory is 64 KB, this means that the memory size, in bytes, is equal to the following quantity:
64 KB = 2⁶ * 2¹⁰ bytes = 2¹⁶ bytes.
In order to address this quantity of cell positions, the address bus must be able to address 2¹⁶ bytes, so it must have 16-bit wide.
