The Air Force has been flying 31 GPS satellites in Mid Earth orbits at an altitude of 20,200 km. Use the same steps, and show the same complete calculations with units, to find the tangential velocity, centripetal
acceleration, and centripetal force if one satellite's mass is 1660 kg and has a period of 12 hours.
Remember to add the radius of the Earth to the altitude above the Earth.

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.

explanation:

v=uf/(u-f)

= 5.-10/(5+10) convex lens has negative focal length

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
