Two light bulbs are 1.00 m apart. From what distance can these light bulbs be marginally resolved by a small telescope with a 3.90 cm -diameter objective lens

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.

it becomes positively charged by charging it

we need to know the time interval during which the force acts. impulse of force = momentum change
