Answer:
Explanation:
We have here values from SI and English Units. I will convert the units to English Units.
We hace for the power P,


we have other values such
and
(specific weight of the water), and 0.85 for \eta
We need to figure the flow rate of the water (V) out, that is,

Where
is the turbine efficiency, at which is,

Replacing,


With this value (the target of this question) we can also calculate the mass flow rate of the waters,
through the density and the flow rate,

converting the slugs to lbm, 1slug = 32.174lbm, we have that the mass flow rate of the water is,

Like they said the leopard seal will overpopulate and kill out all of the other animals. Because it would be at the top of the chain then without the killer whale. Therefore, since it is at the top of the chain it will overpopulate because it has nothing to eat/kill it so then they would eat the animals lower than them<span />
Answer:
1 day
Explanation:
The spinning movement of Earth around its axis is known as Earth's rotation.
The Earth rotates around the Sun in 1 day that is 24 hours but once in every 23 hours, 56 minutes, and 4 seconds with respect to other stars.
According to the Indian astronomer Aryabhata, Earth rotates about its axis daily.

Answer:
The amount that is "vented" out by "the fans" is <u>$0.50</u> for 10 hours.
Option: a
<u>Explanation</u>:
"Energy discharged by air in every hour" can be determined by,

Q = heat energy (Joules, J)
m = mass of a substance (kg)
c = specific heat (units J/kg∙K)




∆T = 10 hours

Q = 576 × 1.00 × 10
Q = 5760 kJ/hours
W = 1.6 kwh
We know that, “Coefficient of performance” (COP)


Given that, COP = 3.2

W = 0.5 kwh
The unit cost of electricity is $0.10/kWh
The unit cost of electricity is $0.10/kWh
Unit electricity cost for 10 hours = 0.5 × 10 × 0.1$
Unit electricity cost for 10 hours = $0.5
The amount that is "vented out" by "the fans" is $0.50 for 10 hours.
