Amplitude: the height of the wave
wavelenght: the distance betweeen adjacent crests
period: the time it takes for one complete wave to pass a given point
The average speed is the distance per time ratio (a scalar quantity) Speed is ignorant of direction. Velocity is a vector quantity. It is aware of direction.
C. Forces cannot be quantified
Forces always act in pairs and are subject to change
The force pushing back to you would be 5 newtons as Newtons 3rd law says that every action force has an opposite but equal reaction force acting upon it (if i remember correctly )
<span>By Newton's second law of motion, we know that the resultant force acting on a body is directly proportional to the mass of the body and directly proportional to its acceleration. In system international (SI) units, the value of the constant of proportionality constant is 1. Therefore, the equation for Newton's second law of motion becomes: F = ma, where F is the resultant force, m is the mass and a is the acceleration of the object. Substituting the values of m and a into this formula, we get the result: F = 12 x 4 = 48. The SI unit for force is the Newton; therefore, <u>the answer is 48 Newtons.</u></span>
