My guess would be B and D.
Answer:
-3874₁₀ = 1111 1111 1111 1111 1111 1111 1101 1110₂
Explanation:
2's complement is a way for us to represent negative numbers in binary.
To get 2's complement:
1. Invert all the bits
2. Add 1 to the inverted bits
Summary: 2's complement = -N = ~N + 1
1. Inverting the number
3874₁₀ = 1111 0010 0010₂
~3874₁₀ = 0000 1101 1101₂
2. Add 1 to your inverted bits
~3874₁₀ + 1 = 0000 1101 1101₂ + 1
= 0000 1101 1110₂
You can pad the most signigicant bits with 1's if you're planning on using more bits.
so,
12 bits 16 bits
0000 1101 1110₂ = 1111 0000 1101 1110₂
They asked for double word-length (a fancy term for 32-bits), so pad the left-most side with 1s' until you get a total of 32 bits.
32 bits
= 1111 1111 1111 1111 1111 1111 1101 1110
The environmental and energy problem Kenya faces as far computer installations are concerned can be avoided by
- Knowing and finding out the key aspect of ICT strength.
- Create an holistic judgements in the assessment of ICT capability. Promote the use of solar power.
<h3>How can we overcome ICT challenges?</h3>
There are a lot of Energy Challenges in terms of ICT in Kenyan and it is good the government and the people work towards energy in terms of sustainable ICT.
Therefore, The environmental and energy problem Kenya faces as far computer installations are concerned can be avoided by
- Knowing and finding out the key aspect of ICT strength.
- Create an holistic judgements in the assessment of ICT capability. Promote the use of solar power.

Is it a multiple choice answer? if so would like to see the answers as there are TONS of effective ways and if i list one it may not be in that list you have if its multiple choice.
Answer:
200 nm
Explanation:
We need a constructive interference to see the bright reflection
we know that 
where m=1 and 
is the wavelength of the gasoline
so 
putting the value of m and in thickness equation
so the thickness of the film will be 200 nm
