Explanation:
Gravity
Gravity is one major force that creates tides. In 1687, Sir Isaac Newton explained that ocean tides result from the gravitational attraction of the sun and moon on the oceans of the earth (Sumich, J.L., 1996).
Answer:
There would be a pressure drop in the direction of the higher opening. This will force air to move in from the lower opening and force it to leave through the higher opening. This will create a convectional movement of air, cooling and ventilating the tunnel.
Explanation:
This is in accordance with bernoulli's law of fluid flow which states that the pressure exerted by a moving fluid is lesser than it would exert if it were at rest.
Answer:
D. It has a low resistance and allows charges to move freely.
Explanation:
The high conductivity of copper allow charges to move freely without the need of too much force. The conductivity decreases with increase in resistance. Low resistance also means less heating of the conductors. This property of copper makes it ideal for use in the manufacture of electric cables and conductors for various gadgets.
well, you divide 4 by 5, so .8
.8 of a mile is 4224 feet.
i really hope this helps :)
Do not forget that mass = <span>volume x density
</span>Mass of 1 cm^3 = Density[/tex]

Then eventually we can find <span>mass of 5 cm^3 : =
</span>

So the answer is D
<span>And that's it. I'm sure it will help.</span>
