Explanation:
thats all i know so thank me when yoiu get them right:)
Wind farms, solar collectors, and nuclear power plants generate no pollution.
But wind farms make noise, wind and solar are both hazardous to birds, and there's no known means of disposing of nuclear plant waste that's completely safe.
<span>Let F be the force of gravity, G be the gravitational constant, M be the mass of the earth, m your mass and r the radius of the earth, then:
F = G(Mm / (4(pi)*r^2))
The above expression gives the force that you feel on the earth's surface, as it is today!
Let us now double the mass of the earth and decrease its diameter to half its original size.
This is the same as replacing M with 2M and r with r/2.
Now the gravitational force (F' ) on the new earth's surface is given by:
F' = G(2Mm / (4(pi)(r/2)^2)) = 2G(Mm / ((1/4)*4(pi)*r^2)) = 8G(Mm / (4(pi)*r^2)) = 8F
So:
F' = 8F
This implies that the force that you would feel pulling you down (your weight) would increase by 800%!
You would be 8 times heavier on this "new" earth!</span>
Answer:
magnitude of the gravitational force is 9.04 × N
Explanation:
given data
altitude = A = 612 km = 612000 m
mass M = 11,100 kg
mass of the Earth m = 5.97 × kg
Earth average radius = 6.38 × m
to find out
magnitude of the gravitational force
solution
first we get here distance from space to centre of earth that is
distance = altitude + earth radius
distance = 612000 + 6.38 × m
distance = 6.99 × m
so now we get here magnitude of the gravitational force that is express as
magnitude of the gravitational force F = ...........1
here G is gravitational constant that is 6.67 × Nm² /kg and M is mass of space and m is mass of earth
put here all value we get
F =
F =
F = 9.04 × N
so magnitude of the gravitational force is 9.04 × N
