Answer:
Contact glasses.
Explanation:
-Anytime you put on a pair of glasses, or see light bend through a glass of water or a prism, this rule is in action.
-In short, Snell's law governs the angle by which electromagnetic radiation such as light refracts, or changes direction, as it passes from one material to another and slows down.
This can be explain through Newton’s first law of motion where an
object at rest remain in rest unless acted upon by an unbalanced force. Hence,
the dust particles having inertia and trapped within the pores of the carpet
has the tendency to remain at the state of rest, it does not move and resist
motion but when the carpet is beaten with a stick, dust comes out because the
force from a stick acted upon it.
Answer:
A . pE=mgh 450kg*50m*10m/s^2=225000Joule
Explanation:
potential energy equals (mass) (gravity) (height)
Answer:
Equilibrium or coordination
Explanation:
The body's equilibrium is it's way to maintain balance, and perfect distribution of weight. When no force is acting to make a body move in a line, the body is in translational equilibrium; when no force is acting to make the body turn, the body is in rotational equilibrium.
