The phase of the Moon must be new, and the nodes of the Moon's orbit must be nearly aligned with Earth and the Sun.
Definitely the first: the water molecule is polar. :)
3.0 A i got it off Quizlet and there usually always right lol can't submit tho my answers to short.... Dot dot dot
The runner runs 8 meters per second or 28.8 kilometers per hour
Using the graph, which describes how Henry ran the 100m race;
a) It takes Henry 20seconds to run 100m
b) Henry's average speed over the race is; 5m/s.
According to the linear graph which describes the distance ran by Henry during the 100m race as a function of time.
a) Since the distance from start ran by Henry is plotted on the vertical axis, and the time is plotted on the horizontal axis;
To determine how long it took Henry to run 100m; The point corresponding to 100m is traced downward from the line of the graph and we find out that;
It takes Henry 20seconds to run 100m
b) Henry's average speed over the race is simply;
The slope of the distance-time graph.
Therefore,
- Average speed = (100-0)/(20-0)
Therefore, Henry's average speed over the race is; 5m/s.
