If a pointer on a spring scale moves 0.0254 m when a 2.224 N weight is fastened to the hook, the pointer will move how many m when a 17.79 N weight is used?
17.79/2.224=x/.0254
To find out how much the pointer will move when a 17.79 N weight is used, let's start by understanding the relationship between the weight applied to the spring scale and the movement of the pointer.
In this case, it's given that when a 2.224 N weight is fastened to the hook, the pointer moves 0.0254 m. This implies that there is a linear relationship between the weight applied and the displacement of the pointer.
To find how much the pointer will move when a 17.79 N weight is used, we can set up a proportion:
(weight 1 / displacement 1) = (weight 2 / displacement 2)
Let's substitute the values we have:
(2.224 N / 0.0254 m) = (17.79 N / displacement 2)
Now, we can solve for the unknown displacement 2:
displacement 2 = (17.79 N * 0.0254 m) / 2.224 N
Calculating this expression will give us the answer.
