According to newton�s first law of motion, if there is no net force (unbalanced forces) acting on an object that is moving at a constant 30 mph, the object will:
question 2 options:

continue to move at 30 mph

eventually come to a stop

change its inertia

accelerate

Continue to move at 30mph

Explanation:

Newton's first law states that a body continues to remain at rest or in uniform motion unless an external force acts on the object .

Here given that The object is moving at 30 mph is acted with a net force = 0

Since net force = 0  there will be no external force

By the first law it continues to remain in its state of uniform motion

Here the car performing a uniform motion with uniform speed of 30mph

Hence it continues to do so

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.

not too sure thinking all accelerations are pointed down
