Answer:
The answer is the Earth is tilted as the Earth makes its journey for the year around the Sun.
In general the earth is tilted at angle of 23.5 degrees from vertical axis. So that the Earth always pointing to one side as it revolves around the Sun. This causes varying amounts of Sun light around the Earth during the years gives us seasons.
So here we conclude that the axis of the Earth is most important thing, why the seasons occur.
Tilt:
Whenever the Earth lean towards the Sun, summer season occurs and lean away from the Sun winter season occurs. In between these two spring and Autumn occurs.
Answer: Creative thinking
Explanation:
It should be noted that, Creative Thinking is the method by which a problem is solved with the help of thinking skills.
The thought that is present in mind is tries in the practical life so that the problem can be solved.
Going by the question asked, Mandleev was trying to arrange elements in a logical way. He thought of arranging the elements based on the atomic weight.
This gives a good oexample of creative thinking in which the thinking is applied and a logical result is product of the thinking.
Answer:
change in entropy is - 5.7627 J/K
Explanation:
Given data
temperature = 22.0°C = 22 + 273 = 295 K
work is done = 1700 J
to find out
change in entropy
solution
we know that change in entropy = Q /T ......1
from 1st law of thermodynamic we know
Q =W for change in internal energy = 0
Q = -1700 J
so from equation 1
change in entropy = - 1700 / 295
change in entropy = - 5.7627
so change in entropy is - 5.7627 J/K
The resultant of the vectors is .
<h3>What is a resultant vector?</h3>
A resultant vector is the vector sum of two or more vectors.
The given vectors;
- Height of vector A = HA
- Height of vector B = HB
- Height of vector C = HC
The height of vector B is the resultant of the three given vectors.
When the vectors are drawn from head to tail, the vector B forms the resultant of the two other vectors (A and C).
Thus, the resultant of the vectors is .
