Answer:
D. The number of winter coats sold and the temperature outside.
Explanation:
A negative correlation can be described as a relationship existing between two variables such that as one of these variables goes up, the other variable would go down and vice versa.
With this explanation in mind, as the temperature outside increases, less winter coats would be sold because an increase in temperature would mean more heat and hotness. People would be uncomfortable wearing thick clothing.
<span>The four main stages of the sun's predicted evolution in order from beginning to end are as follows:
main sequence (when a star's core is fusing hydrogen);
red giant (larger star, where no hydrogen remains in the core);
planetary nebula (surrounds an aging star; ring shaped nebula made of gas); and
white dwarf (smaller star that tends to be as large as an actual planet; after nebula state).</span>
Explanation:
It is given that,
Radius of bowl, r = 3 m
A small block is released from rest from the edge of a large hemispherical friction less bowl. Let v is the speed of the mass when it passes through the bottom of the bowl and u is the initial speed of the mass, u = 0. Using conservation of energy as :
h = r = 3 m
v = 7.66 m/s
or
v = 7.7 m/s
So, the speed of the mass at the bottom of the bowl is 7.7 m/s. Hence, this is the required solution.
Answer:
You could try finding a familiar peer to join the activity with your child. Or ask your child who their friends are at school, or what they look for in a friend at school.
The statement that describes how work and power are similar is D. you must know time and energy to calculate both.
I am not completely sure though, so I hope this helps. :)
