Apiece of steel is held firmly in the jaws of a vise. a force larger than 3350 n will cause the piece of steel to start to move out of the vise. if the coefficient of friction between the steel and each of the jaws of the vise is 0.825 and each jaw applies an equal force, what is the magnitude of the normal force exerted on the steel by each jaw?

N=2030.30 N

Explanation:

Given that

F= 3350 N

Coefficient of friction ,μ =0.825

Lets take N is the normal force

We know that friction force fr

fr= μ N

The total force in left side = 2 fr

Total force in right side =F

So by equating the above two forces

F= 2 fr

3350 = 2 x 0.825 x N

N=2030.30 N

Neptune is the eighth planet from the sun. it was the first planet to get its existence predicted by  mathematical calculations  before it was actually seen through a telescope on sept. 23, 1846. irregularities in the orbit of  uranus  led french astronomer alexis bouvard to suggest that the gravitational pull from another celestial body might be responsible. german astronomer johann galle then relied on subsequent calculations to   spot neptune via telescope. previously, astronomer galileo galilei sketched the planet, but he mistook it for a star due to its slow motion. in accordance with all the other planets seen in the sky, this new world was given a name from greek and roman mythology — neptune, the roman god of the sea.
