Answer:
0.304 m/s2
Explanation:
If the first child is pushing with a force of 69N to the right and the 2nd child is pushing with a force of 91N to the left. Then the net pushing force is 91 - 69 = 22 N to the left. Subtracted by 15N friction force then the system of interest is subjected to F = 7 N net force tot he left.
We can use Newton's 2nd law to calculate the net acceleration of the system
The letter refers to the shape of the orbital. The letters go in the order s, p, d, f, g, h, i, j, etc. The letters s, p, d, and f were assigned for historical reasons that need not concern us. All we have to do is remember the shapes that correspond to each letter.
hope this helps!
Droughts are a real concern because although water is constant, water is not evenly distributed amongst every location on Earth. Many places experience a monsoon season or other extremely wet period, but many other places feature a more desert terrain and climate. In there locations, there is little to no water accessible.
Also, if a normally wet location is experiencing a drought, plants and agriculture that rely on an abundance of water could die, limiting food sources.
