Air mass creates the temperature of the sky by the clouds,
To determine whether an object is in motion or not, you first
need to specify a reference point, because there's no such
thing as "real" motion, only motion relative to something.
Once you've named the reference point, you have to look at
the object at two different times. Each time you look at it, you
measure its distance and direction from the reference point.
If there's any difference in these measurements from one time
to the next, then the object has had average motion during the
period between the two observations.
That's the best you can do ... find average motion during some
period of time. You can never definitely tell whether or not the
object ever stopped during that time. But you can sneak up on
it by making the time period between the two observations shorter
and shorter.
Answer:
True
Explanation:
Generally, science has several calculations which directly require Mathematical knowledge. Concepts such as balancing forces, magnification, calculation of moles which are in sciences require proper understanding of Mathematics. It's not only students born and raised in the US who perceive Mathematics as a useful and necessary science but also other parts of the globe. Therefore, the statement is true.
Absolutely ! If you have two vectors with equal magnitudes and opposite
directions, then one of them is the negative of the other. Their correct
vector sum is zero, and that's exactly the magnitude of the resultant vector.
(Think of fifty football players pulling on each end of the rope in a tug-of-war.
Their forces are equal in magnitude but opposite in sign, and the flag that
hangs from the middle of the rope goes nowhere, because the resultant
force on it is zero.)
This gross, messy explanation is completely applicable when you're totaling up
the x-components or the y-components.
