Electric power is to be generated by installing a hydraulic turbine-generator at a site 120 m below the free surface of a large

iogann1982 [59]

Answer:

P = 2234400 Watt

Explanation:

Power generation is given as rate of work done

Here the turbine generator is located at 120 m below the free surface

So here rate of work done is given as rate of potential energy

$Power = \frac{dw}{dt}$

$Power = \frac{mgh}{t}$

so we have

$Power = (\frac{dm}{dt})gh$

now we have

$Power = 1900(9.8)(120) = 2234400 Watt$

so the power generation potential will be 2234400 Watt

An astronaut in a satellite 1600km above the Earth experience a gravitational force magnitude 700N on earth.The Earth's radius i

Brilliant_brown [7]

Answer:

The magnitude of the gravitational force which the astronaut experience in satellite $= 448$ Newton

Explanation:

As we know

Gravitational force F = $\frac{GMm}{r^2}$

Where G is the gravitational constant $6.67 * 10^{-11}$

M is the mass of earth $= 6* 10^{24}$

m is not given

r is the radius of earth $6 400*10^3$

Substituting the given values, we get -

$F = \frac{6.67*10^{−11}*6*10^{24}* m}{(6400*10^3)^2}$

$m = 71.6$ Kg

Gravitational force in the satellite

$F = \frac{6.67*10^{−11}*6*10^{24}* m}{(6400*10^3 + 1600 *10^3)^2}\\F = 448$ N

All Houston Methodist buildings system wide have an emergency power generator that turns on to supply emergency power after norm

lesya692 [45]

Answer:

D. 10 seconds

Explanation:

All Houston Methodist Hospital buildings employs the use of EPSS(Emergency Power Supply System). This system employs the use of an emergency power generator that turns on to supply emergency power after normal power shuts down within 10 seconds during power outage.

Due to it being used in a hospital the importance of this emergency power system cannot be overemphasized as it is used to provide power supply to hospital equipment such as life support machines etc.
