Answer:
Explanation:
What you know is that the electrical energy comes from the wind turbine. Therefore the x must identify the type of energy that the wind turbine represents.
It must represent mechanical energy because blades of the wind turbine turns to produce electrical energy.
Answer:
36.63 Torr
Explanation:
You need to use two expressions, one for pressure and the other with the relation of density and height of the column.
For the pressure:
P = h * d * g (1)
h is height.
d density
g gravity
The second expression put a relation between the densities and height of the column so:
d1/d2 = h1/h2 (2)
let 1 be the phthalate, and 2 the mercury.
Let's calculate first the relation of density:
d1/d2 = 13.53 / 1.046 = 12.93
Now with the first expression, we can calculate the pressure so:
P = hdg
We have two compounds so,
h1d1g = h2d2g ---> gravity cancels out
From here, we can solve for h2:
h2 = h1*(d1/d2)
replacing:
h2 = 459 / 12.53
h2 = 36.63 mm
1 mmHg is 1 torr, therefore the pressure of the gas in Torr would be 36.63 Torr
Answer:
1 por 10 y otro por el culo
The
balanced chemical reaction is:<span>
N2 + 3H2 = 2NH3
<span>We are given the amount of the product to be
produced. This will be the starting point of our calculations.
17 mol NH3 ( 1 mol N2 / 2 mol NH3 ) = 8.5 mol N2
Therefore, the required N2 to produce the given amount of ammonia is 8.5 mol.</span></span>
The Earth spins on its axis and revolves around the Sun. The tilt of its axis with respect to the Sun causes the Earth's seasons. The Earth also follows the Sun's rotation around the center of the Milky Way galaxy, which is moving through space.
