B) 20 cm
The height and distance will be the same. Only the image will be laterally inverted.
Answer:
= 625 nm
Explanation:
We now that for
for maximum intensity(bright fringe) d sinθ=nλ n=0,1,2,....
d= distance between the slits, λ= wavelength of incident ray
for small θ, sinθ≈tanθ= y/D where y is the distance on screen and D is the distance b/w screen and slits.
Given
d=1.19 mm, y=4.97 cm, and, n=10, D=9.47 m
applying formula
λ= (d*y)/(D*n)
putting values we get
on solving we get
= 625 nm
Answer:
The maximum height is 10.0m
Because <span>two organisms with exactly the same </span>niche can't survive in the samehabitat<span> (because they compete for exactly the same resources, so one </span>will<span> drive the other to extinction). However, species whose </span>niches<span> only partly overlap may be able to coexist.</span>
Answer:
a) Vf = 4.95 m/s
b) t = 0.51s
Explanation:
take downwards as positive.
let Vf be the final velocity as the cucumber reach the bottom of the bin and Vi be the initial velocity of the cucumber when they dropped.
a ) from equations of motion:
(Vf)^2 = (vi)^2 +2g×(x - x0) ,
<em>since x0 = 0 m and Vi = 0 m/s.</em>
Vf = \sqrt{2g×(x)} = \sqrt{2(9.8)×(1.25)} = 4.95 m/s, downwards
therefore, the cucumber will reach the bottom of the bin with a speed of 4.95 m/s.
b) from equations of motion:
Vf = Vi + g×t
Vi = 0 then:
t = Vf/g = 4.95/9.8 = 0.51 s
therefore, the cucumber will take 0.51 seconds to reach the bottom of the bin.
