If the moon were twice as massive but twice as far from earth, high tides on earth would be – (think of it’s force)

a. higher
b. lower
c. no different

The answer would be B. Lower.

Explanation:

This is because Force between two bodies is directly proportional to the mass of an object, but inversely proportional to the square of the distance between them.

So if the mass of the moon becomes twice, the force would also be twice as strong. (2 F ) , but if the distance is doubled, this force (2 F ) would be quartered ( 2F/4 = F/2 ) which would be half of the original force F.

Hence if the force is halved, the tides would be lower.

i think it because equal matrices have equal dimensions, only square matrices can be symmetric. for all indices and . every square diagonal matrix is symmetric, since all off-diagonal elements are zero. in linear algebra, a real symmetric matrix represents a self-adjoint operator over a real inner product space.
