Known :
v1 = 0 m/s
vt = 10 m/s
t = 4 s
Asked :
a = ...?
Answer :
a = (vt - v1)/t
= (10 - 0)/4
= 10/4
= 5/2
= <u>2 ½</u><u> </u><u>m/</u><u>s</u><u>²</u>
= <u>2</u><u>.</u><u>5</u><u> </u><u>m/</u><u>s</u><u>²</u>

Answer:
D
Explanation:
Refraction is The bending of light from its straight line path when it travels from one medium to another. It is also a change in the direction of travel of light, sound, or other waves crossing a boundary.
Well, your muscles are made of of the two (most important) filaments. When one of them moves over the other <span>filaments, the muscles is contracted. If there is an answer choice, I may be able to provide you with a more accurate answer, if this did not already help. ;)</span>

Explanation: not sure if this is what ur asking for but those are the symbols
Answer:
0.1923 λ
Explanation:
t = thickness of the coating material applied over the lens
n = index of refraction of the coating material = 1.3
m = minimum order = 0
λ = wavelength of the incident light
For destructive interference , the condition is given as
2 n t = (m + (0.5)) λ
Inserting the values
2 (1.3) t = (0 + 0.5) λ
t = 0.1923 λ
