Answer: El trabajo realizado al desplazar el bloque es: 75 N.m
Datos:
Fuerza= F= 25 N
Distancia= d= 3 m
Explicación:
El trabajo es el producto de la fuerza ejercida sobre un cuerpo con el desplazamiento producido por la fuerza. Para que exista trabajo, la dirección de la fuerza debe ser igual a la dirección del desplazamiento.
Trabajo= Fuerza x Desplazamiento
Reemplazando los datos:
T= 25 N * 3 m
T= 75 N.m
The answer would be in space because there is no matter and if there isn't matter the sound of a ringing cell phone could not be transmitted.
Answer:
Explanation:
First, we have to calculate the maximum height reached by the object. We use the equations of uniformly accelerated motion:
In order to calculate this, we have to know the time taken by the object to reach the maximum height:
Now, we can calculate y:
Now, we calculate the time taken by the object in free fall:
Finally, adding and , we get the total time until the object impacts the ground:
I believe the answer would be A. because a magnet has both a south and a north pole, and electrical charges are formed by positive and negative forces. Hope I helped!
Answer:
The value is
Explanation:
From the question we are told that
The mass of the block is
The force exerted is
The frequency is
Generally the spring constant of the spring is mathematically represented as
=>
=>
Generally the spring constant is also mathematically represented as
=>
