m. The power given to
the turbine is
Choose the correct answer.
1 10 kW
2 6 kW
3 100 kW
4 600 kW
​

Answer 1

Answer:

Given,

Maas of planet = 6*10^24 kg

Radius of planet = 6.4*10^6 m

G = 6.7*10^-11 Nm^2/kg^2

As we know that,

g = (G*m)/r^2

or, g = {(6.7*10^-11)*(6*10^24)}/(6.4*10^6)^2

or g = 9.81 meter per second square

Answer 2

Answer:

100 kw

Explanation:

1 min = 60 sec

6000÷60=100

= 100 kw
