Idrk tbh but aye add me on sc: alexboxing505 hehehehehe
a) Summer in the northern hemisphere is when days are longest. Actually, the first day of summer is the longest day, so the longest days are the ones in late spring and early summer.
b) Days and nights are equal length at the spring and fall equinoxes.
The kinetic energy is proportional to the temperature.
<h3>
What is the relation between temperature and kinetic energy?</h3>
So first, we know that the kinetic energy of an object is given by:
K = (1/2)*m*v^2
Where v is the velocity and m is the mass.
We know that substances are made of molecules, and these molecules are tiny objects that move. As the temperature increases, you should see that the speed of motion of these particles increases (this is why dilation happens). So, if the velocity increases, then also increases the kinetic energy of the molecules in the substance.
The thermal velocity is approximated by:
Where (k/m) is a constant, now, if you replace that in the kinetic energy equation, you can see that the kinetic energy is proportional to the temperature.

When the above situation occurs, we can say that the income elasticity of demand for automobiles is<u> 1.2.</u>
<u />
<h3>What is the income elasticity of the automobiles?</h3>
This can be found by the formula:
= Change in quantity demanded of automobiles / Change in income
Solving gives:
= 30% / 25%
= 1.2
In conclusion, the income elasticity here would be 1.2.
