Question

6. G and g are two ways of writing the same quantity

7. The value of G on the moon is about one-sixth of its value of the earth.

8. The value of g at the centre of the earth is zero.

9. Mass and weight are measured in different units.


10. Mass decreases with height above the earth's surface.​

Answer 1

Answer:

7 is true

Explanation:

is this the answer or i have to tell something else as u have not written the clear question except 5 statements

Answer 2

Answer:

6) True

7) True

8) True

9) False

10) True

Explanation:

6) g is for acceleration due to gravity & G is for universal gravitational contact.

7) The gravitational force on the moon is 6 times lesser than the earth.

8) Acceleration due to gravity varies directly proportional to distance from center, i.e. r.

But varies 1/r² when r > R

expression is given by g= GM / r² where r > R

and g = GMr / R³ if r > R

so when r=0 then g will be zero.

9) Mass and weight are both are measured in kilograms (kg).
