Answer:
<u> a = V final 2___v initial2</u>
28
Explanation:
By definition for contant acceleration <u>a = V final ___v initial</u>
t
Furthermore the average speed is <u>V abg = v initial +v final</u>
2
Combine these relationships to eliminate t. 8 = Vabg t.
<span>The "scientific method" consists of forming a hypothesis (a statement about what the researchers think is true), collecting data that might confirm or refute the hypothesis, and then examining the data to see how well or poorly they support the original hypothesis.</span>
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
Answer:
The correct answer is violet, blue, green, and red emission lines.
Explanation:
When samples of pure elements are heated they emit a continuous spectrum of electromagnetic radiation. When elements are heated at very high temperatures, the electrons get excited and they jump to consequent orbits and this results in transmission of electromagnetic radiation. The four lines visible in the emission spectrum of hydrogen are violet, blue, green, and red, the most intense of which is at 656 nanometre.
