Answer:
The slope of the position time graph gives the velocity.
Explanation:
The slope of the position time graph gives the value of velocity.
In first graph,
The slope is constant in both the parts but positive . So the velocity is also constant and positive for both the parts. and more than the second part, so the initial velocity is more than the final velocity.
In the second graph,
The slope is constant in both the parts but negative. So, the velocity is constant but negative for both the parts. Initial velocity is more negative than the final velocity.
Answer:
Convection
Explanation:
Convection is heat transfer due to a density differential within a fluid. As water's temperature increases in the presence of a heat source, it will become less dense and rise. As it moves up and away from the heat source, it cools and becomes more dense and sinks.
Answer:
ok thanks for giving point
Answer: The air entering on top of the wing speeds up. The air entering high pressure area on bottom slows down. That is why air on top moves faster.
Explanation:
Since the cation (A) has a charge twice in magnitude than that of the anion (X), you can say the magnitude of the charge of the cation is 2c, while the magnitude of the charge of the anion is c.
Also remember that cations are positive ions, so the charge would be +2c, and that anions are negative ions, so the charge would be -c.
A binary ionic compound of A and X would have to have a net charge of zero. If A has a +2c charge, you would need two X anions to balance out every A cation, so the formula would be:
The simplest formula would be
