Answer:
|Fr| = 50*√2 [N]
Explanation: (See Annex )
En el diagrama de cuerpo libre ( mostrado en el anexo) se ve que, al ser las dos fuerzas iguales (50 N) el paralelogramo formado para encontrar la resultante de las fuerzas (Fr) es un cuadrado, y la diagonal de ese cuadrado ( que es al mismo tiempo la hipotenusa del triangulo recto OPA ) es igual a:
Hipotenusa = |Fr| = √ (50)² + (50)²
|Fr| = √2* (50)²
|Fr| = 50*√2 [N]
Parallel to the velocity city is zero
Rating of perceived exertion
Answer : Option B) Shape and Position.
Explanation : Potential energy is defined as the stored energy in an object due of its position or its configuration; whereas the kinetic energy is defined as energy which a body can possesses because of its motion.
With the definitions, it is clear that potential energy has a distinguishing property of shape and position from kinetic energy.
