<em>its wave length </em>
<em>its wave lenght because how its measure</em>
Answer:
I font now but I think its 2.0 + 78 w -60
Answer:
4.2 m/s
Explanation:
The velocity-time graph is piecewise linear. The acceleration in each of the three segments of the graph is uniform. The instant lies between and t = 6.0s 100 s, so the acceleration must be calculated using the slope of the middle segment.
a =
(9.6 -2.4)m/s
------------------
(10.0 -6.0)s
= 1.8 m/s2
The instantaneous velocity is to be found after the object accelerates over an interval T = (7.0 - 6.0) s = 1.0 s, starting from a velocity of 2.4 m/s,
So the velocity at t = 7.0 s is
v = u + aT = 2.4 m/s + (1.8 m/s2)(1.0 s) = 4.2 m/s
Answer:
T= 563/4= 140.75 nm
Explanation:
Soap bubbles can display impressive colors.
In a bubble there are two surfaces the first surface has a phase shift of 180° and second surface has 0° phase shift.
so total 
wavelength λ= 2π
hence wavelength λ/2
Also λ= 
= 562.9921≅563 nm
also wall thickness T
T= λ/4
⇒T= 563/4= 140.75 nm
The answer should be iron
