This is an expression for the acceleration due to gravity at the depth 'd' below the surface of the earth. This expression shows acceleration due to gravity decreases as we move down into the earth. At the centre of the earth d = R, hence acceleration due to gravity at the centre of the earth is zero.

this is gravitational concept
so
i have asked about elements
ok

Since Scandium has 2 electrons in its 4s orbital and 1 electron in its 3d orbital, it bas a valency of 3. It can lose one, two or all three of its electrons during bond formation.
Hope it helps!
chemical reactions and equations
That is class 11th right?
or class 10
Then you don't need to know
Class 10th only upto 20 elements you need to study
Because you will understand more clearly after studying class 11 and 12 portions
ok
Please mark as brainliest answer
i dont know how to do
it will be there on top of the answer
