I believe the sun is the primary source of energy for Earth's weather system. The sun is the primary energy source for Earth's climate system which is the first set of essential principles of climate sciences. Additionally, it is the primary source that drives all weather events, including precipitation, hurricane and tornadoes. The sun drives the hydrologic cycle, and makes life on Earth possible. 
        
             
        
        
        
Answer:
Earth's orbit is elliptical 
Explanation:
The earth's orbit is not a straight circle and the sun is not in the very center of it. The orbit is more of a wonky oval with the sun closer to one side of it than the other causing the earth's distance from the sun to vary throughout the year.
 
        
                    
             
        
        
        
Answer:
The brakes don't grip the tires as securely as the water prevents a stable grip. The car will skid straight along the road as the tires don't have traction along a wet surface

A) The position of the particle along the straight-line path is given by

where t is the time.
If we substitute t=11 s inside the equation, we find the total distance covered during this time, in feet:

which converted into meters is s=182 m.
b) The average velocity of the particle at t=11 s is equal to the total distance travelled, s=597 ft, divided by the time taken, t=11 s:

We can also calculate it in meters/second:
