Answer:
3 meters per second
Explanation:
72 divided by 3= 24 meters in 8 seconds
24/8= 3, so 3 meters per second
Answer:
Same direction to produce maximum magnitude and opposite direction to produce minimum magnitude
Explanation:
Let a be the angle between vectors A and B. Generally when we add A to B, we can split A into 2 sub vectors, 1 parallel to B and the other perpendicular to B.
Also let A and B be the magnitude of vector A and B, respectively.
We have the parallel component after addition be
Acos(a) + B
And the perpendicular component after addition be
Asin(a)
The magnitude of the resulting vector would be




As A and B are fixed, the equation above is maximum when cos(a) = 1, meaning a = 0 degree and vector A and B are in the same direction, and minimum with cos(a) = -1, meaning a = 180 degree and vector A and B are in opposite direction.
If both the atomic number and mass number each increased by one, then ...
-- the atom would have one more proton in its nucleus,
and
-- whenever it was in a neutral state, it would also have one more electron in its cloud.
