Answer:
A town interested in installing wind turbines to generate electricity measures the speed of the wind in the town over the course of a year. They find that most of the time, the wind speed is pretty slow, while only rarely does the wind blow very fast during a storm. What would be the best measure of the central wind speed they should report to the mayor?
The median is the best measure of the central wind speed they should report to the mayor because the distribution is not symmetric. The distribution of wind speeds is skewed.
Explanation:
Based on the scenario described in the question, the median is the best measure of the central wind speed they should report to the mayor because the distribution is not symmetric. The distribution of wind speeds is skewed.
The initial compression of the spring is determined as 0.54 m.
<h3>What is the compression of the spring?</h3>
The compression of the spring is determined by applying the principle of conservation of linear momentum as follows;
E = U
mgh = ¹/₂kx²
2mgh = kx²
x² = 2mgh/k
x = √(2mgh/k)
where;
- m is the mass of the projetcile
- h is the height
- k is the spring constant = 0.07 N/cm = 7 N/m
- x is the compression of the spring
x = √(2 x 0.021 x 9.8 x 5)/7)
x = 0.54 m

So the mass of water remains the same when it freezes. The mass of any substance is the same when it changes phase from liquid to gas, or solid. This is the principle of mass conservation.
