Answer:
Explanation:
according to snell's law
refractive index of water n_w is 1.33
refractive index of glass n_g is 1.5
now applying snell's law between air and glass, so we have
![\beta = sin^{-1} [\frac{n_g}{n_a}*sin\alpha]](https://tex.z-dn.net/?f=%5Cbeta%20%3D%20sin%5E%7B-1%7D%20%5B%5Cfrac%7Bn_g%7D%7Bn_a%7D%2Asin%5Calpha%5D)
we know that
1. One
2. Oohm
Hope this helps
Answer:
2nd answer 3.2m/s is a scalar l, all others are vectors.
Explanation:
In order to be considered as a vector a certain quantity must have both a magnitude and a direction.
The most common example is velocity. It has both magnitude and direction, like the 1st and the last answers.
The 3rd answer is an acceleration. It is also given with its direction. So we have to consider it also as a vector.
But 2nd answer has no direction mentioned, so it is considered as a scalar.
The snake and rat both share the same ancestor population that had a quadrate bone, which was inherited from an ancestor population.
<h3>What is a homo-logous structure?</h3>
A homo-logous structure is a trait that may or not have the same function but has a common evolutionary origin.
A homo-logous structure can be used to trace the evolutionary relationships between species.
Conversely, an analogous structure has the same function but it does not reflect an evolutionary origin.
