Answer:
Option (B)
Explanation:
A lift chart usually refers to a graphical representation that is mainly used in order to improve the drawbacks of a mining model by making a comparison with any random guess, and also helps in determining the changes that occur in terms of lift scores.
It describes the binary classification of the problems associated with the mining activity. This type of chart is commonly used to differentiate the lift scores for a variety of models, and picking the best one out of all.
Thus, the correct answer is option (B).
Explanation:
Formula which holds true for a leans with radii
and
and index refraction n is given as follows.
Since, the lens is immersed in liquid with index of refraction
. Therefore, focal length obeys the following.
and,
or,
= 32.4 cm
Using thin lens equation, we will find the focal length as follows.
![\frac{1}{f} = \frac{1}{s_{o}} + \frac{1}{s_{i}}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7Bf%7D%20%3D%20%5Cfrac%7B1%7D%7Bs_%7Bo%7D%7D%20%2B%20%5Cfrac%7B1%7D%7Bs_%7Bi%7D%7D)
Hence, image distance can be calculated as follows.
![s_{i} = \frac{fs_{o}}{s_{o} - f}](https://tex.z-dn.net/?f=s_%7Bi%7D%20%3D%20%5Cfrac%7Bfs_%7Bo%7D%7D%7Bs_%7Bo%7D%20-%20f%7D)
![s_{i} = \frac{32.4 \times 100}{100 - 32.4}](https://tex.z-dn.net/?f=s_%7Bi%7D%20%3D%20%5Cfrac%7B32.4%20%5Ctimes%20100%7D%7B100%20-%2032.4%7D)
= 47.9 cm
Therefore, we can conclude that the focal length of the lens in water is 47.9 cm.
<span>The velocity would be 54.2 m/s
We would use the equation 1/2mv^2top+mghtop = 1/2mv^2bottom+mghbottom where m is the mass of the bobsled(which can be ignored), vtop/bottom is the velocity of the bobsled at the top or bottom, g is gravity, and htop/bottom is the height of the bobsled at the top or bottom of the hill. Since the velocity of the bobsled at the top of the hill and height at the bottom of the hill are zero, 1/2mv^2top and mghbottom will equal zero. The equation will be mghtop=1/2mv^2bottom. Thus we would solve for v.</span>
Answer:
The moon is 400x smaller but it's also 400x closer so it looks the same size even though it's not
