Answer:
option A
Explanation:
When white light is incident on prism it bends and dispersed into different colors.
According to Cauchy equation, refractive index is inversely proportional to the wavelength of the light.
wavelength of the light in decreasing order
orange > yellow > green > blue
wavelength of the orange light is the highest.
Hence, the refractive index of orange will be lowest.
The correct answer is option A
Final angular speed
ω = v / r = 2.20m/s / ½*35.0m = 0.126 rad/s
and so prior to reaching that final speed
the angular acceleration
α = Δω / Δt = 0.126rad/s / 15.0s = 0.00838 rad/s² ◄
and the tangential acceleration
a = Δv / Δt = 2.20m/s / 15.0s = 0.147 m/s² ◄
OR
a = αr = 0.00838rad/s² * ½*35.0m = 0.147 m/s² ◄
Answer:
The refraction of light at the surface of water makes ponds and swimming pools appear shallower than they really are. A 1m deep pond would only appear to be 0.75 m deep when viewed from directly above. When light emerges from glass or water into air it speeds up again.
Explanation:
<span>
they're both properties of water. both involve the "sticking" property of H2O .</span><span>
cohesion is "sticking" together (water sticking to water) and adhesios is water</span><span>
</span>
"sticking" to something else. They are both important to life processes.
<span>In chemistry, adhesion refers
to the tendency of unlike molecules to bond with one another, while
cohesion refers to the attractive force between molecules of the same
type. Surface tension, which is an essential property of water, illustrates the relationship between adhesion and cohesion.</span>
