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
<h2>
Answer:</h2>
F = 13
<h2>
Explanation:</h2>
Given:
x = false
y = 5
z = 1
F = (4%2)+2*Y +6/2 +(z&&x)
We solve this arithmetic using the order of precedence:
<em>i. Solve the brackets first</em>
=> (4 % 2)
This means 4 modulus 2. This is the result of the remainder when 4 is divided by 2. Since there is no remainder when 4 is divided by 2, then
4 % 2 = 0
=> (z && x)
This means (1 && false). This is the result of using the AND operator. Remember that && means AND operator. This will return false (or 0) if one or both operands are false. It will return true (or 1) if both operands are true.
In this case since the right operand is a false, the result will be 0. i.e
(z && x) = (1 && false) = 0
<em>ii. Solve either the multiplication or division next whichever one comes first.</em>
=> 2 * y
This means the product of 2 and y ( = 5). This will give;
2 * y = 2 * 5 = 10
=> 6 / 2
This means the quotient of 6 and 2. This will give;
6 / 2 = 3
<em>iii. Now solve the addition by first substituting the values calculated earlier back into F.</em>
F = (4%2)+2*Y +6/2 +(z&&x)
F = 0 + 10 + 3 + 0
F = 13
Therefore, the value of F is 13

Answer:
C
Explanation:
All the calculation by computer is performed in base 2. Base 2 is also named as binary computation and it is used in all the computer and digital data processing processors.
Some differences between base 2 and base 10 are:
- Base 2 number system contains 0 and 1 whereas base 10 is from 0 to 9.
- Digital systems works on 0 and 1 logic i.e on and off logic. So we use digital system easily in binary domain whereas, decimal system has 0-9 levels and they are hard to be catered in digital domain.
- Base 10 is used in normal calculations for daily use and binary is only confined to digital domain.
