Roberto and laura are studying across from each other at a wide table. laura slides a 2.2 kg book
toward roberto. if the net force acting on the book is 1.6 n to the right, what is the book's acceleration?

Explanation:

Force = Mass × Acceleration

1.6 = 2.2 × a

a = 1.6/2.2

= 0.73 m/s^2

Note that the acceleration will be negative.

the reason is because the moon has some form of gravity, and that gravity pulls the ocean tides.

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.
