Experiment to determine the refractive index of a glass prism FOCAL LENGTH = 9.5cm i° e° d° 30 43 69 40 41 61 45 39 56 50 37 48
yarga [219]
We are given the data for the angle of incidence and angle of refraction.
The first part of the problem is to plot the deviation and the angle of incidence. The minimum deviation is 37 with 65 degrees as the corresponding angle of incidence. The maximum deviation is 69 with a corresponding angle of incidence of 30 degrees. It is not advisable to use small values for the angle of incidence since it would result to a higher deviation from Snell's Law.

A candy-filled piñata is hung from a tree for Matthew's birthday. During an unsuccessful attempt to break the 4.4-kg piñata, Hay
Margaret [11]

Answer:

The speed of the piñata immediately after being cracked by the stick is v_{fp}=0.59\: m/s.

Explanation:

Using the conservation of linear momentum:

m_{s}v_{is}=m_{p}v_{fp} (1)

Here:

m(s) is the mass of the stick

m(p) is the mass of the piñata

v(is) is the initial velocity of the stick

v(fp) is the final velocity of the piñata        

So, we just need to solve the equation (1) to v(fp).

v_{fp}=\frac{m_{s}v_{is}}{m_{p}}

v_{fp}=\frac{0.54*4.8}{4.4}

v_{fp}=0.59\: m/s

I hope it helps you!

A change in the gene pool of a population due to chance is _____.
Mrac [35]
<span>The correct answer should be a genetic drift. Mutations usually occur over a relatively short period of time and usually start with a single unit that transfers the mutation when they procreate. Genetic drifts separate entire populations and in time create new species that cannot procreate with the original species from whence they came.</span>
