Newton's first law is the law of inertia stating that an object in motion stays in motion at the same speed unless acted on by an equal and opposite force and an object at rest stays at rest unless acted upon by an external force.
If a hockey puck is hit on ice (without friction), it will continue to move until friction or another force stops it. If a hockey puck is sitting in one place, the puck will not move until some external force moves it.
The motion of the hockey puck is a result of the sum of external forces on the hockey puck being unequal.
Answer:
They are younger than rocks fat from mid ocean ridges
Sin and cosine of the acute angle are complementary trigonometric functions. This means that between these trigonometric functions, the rule of complementary acute angles applies: sin64° = cos(90°-64°) = cos26°
So, if we have given cos64° = cosx and we want to determine the value of the acute angle x, given the complementarity of the angles to 90 degrees, the required value of the angle x is 26°.
The answer is: x = 26°
