The main cause of the seasons is earths orbit since each time were in a new season the planet is facing the earth a different way which causes winter etc..
To find velocity on a distance vs time graph, find the slope (of line segment C in this case)
Calculate slope by finding rise (change in x) over run (change in x).
10-30/160-80
-20/80
-1/4
Final answer: B
Hello! Sorry this is a little late!
The answer to your question would best be option C, y<span>es, because electric charges have electric fields surrounding them that allow them to exert forces on other objects without touching them.
I just took this test, and can 100% confirm this is the correct answer!
Hope this helps, and have a great day! :)</span>
Answer:
Final speed of the ball = Vf= 12.52 m/s when it hits the ground
Explanation:
Height = S= 8.0 m
Initial Velocity= Vi = 0 m/s
Final Velocity= Vf =?
Acceleration due to gravity= a=9.8m/s²
Using Newtons third equation of motion
2as= Vf²- Vi²
2(9.8) 8= Vf²- 0
156.8= Vf²
Vf=√156.8= 12.52m/s
Final Speed of the ball is 12.52 m/s
