Answer:
The minimum thickness is 
Explanation:
generally the equation for thin film interference is mathematically represented as
Where t the thickness
m is any integer
n is the refractive index of the film
is the wavelength of light
Since we are looking for the thickness we make t the subject of the formula
m= 0 cause the thickness is minimum at m=0
Substituting values
When someone lifts a book from the ground, the work you use is positive. By lifting the book, you change it's energy and it's original place The book gains, kinectic energy.
Hope I helped.
Answer:20,000 m/s
Explanation: the formula is f=v/lambda so you would do 10,000=v/2 and you multiple the 2 to 10,000 since you were originally dividing and you get 20,000 and your unit is m/s
