Nonmetals in the periodic table have a negative oxidation number. Which statement best explains why?
Tema [17]
They have a negative oxidation number because nonmetals gain electrons, thus making them negatively charged ions (anions). Metals become cations and have a positive charge because they lose electrons.

A stationary 12.5 kg object is located on a table near the surface of the earth. The coefficient of static friction between the
Sophie [7]

When the object is at rest, there is a zero net force due the cancellation of the object's weight <em>w</em> with the normal force <em>n</em> of the table pushing up on the object, so that by Newton's second law,

∑ <em>F</em> = <em>n</em> - <em>w</em> = 0   →   <em>n</em> = <em>w</em> = <em>mg</em> = 112.5 N ≈ 113 N

where <em>m</em> = 12.5 kg and <em>g</em> = 9.80 m/s².

The minimum force <em>F</em> needed to overcome <u>maximum</u> static friction <em>f</em> and get the object moving is

<em>F</em> > <em>f</em> = 0.50 <em>n</em> = 61.25 N ≈ 61.3 N

which means a push of <em>F</em> = 15 N is not enough the get object moving and so it stays at rest in equilibrium. While the push is being done, the net force on the object is still zero, but now the horizontal push and static friction cancel each other.

So:

(a) Your free body diagram should show the object with 4 forces acting on it as described above. You have to draw it to scale, so whatever length you use for the normal force and weight vectors, the length of the push and static friction vectors should be about 61.3/112.5 ≈ 0.545 ≈ 54.5% as long.

(b) Friction has a magnitude of 15 N because it balances the pushing force.

(c) The object is in equilibrium and not moving, so the acceleration is zero.

If a car travels around a gentle curve on a highway at 60 km/h, does the velocity change
Oksi-84 [34.3K]
Yes the velocity changes. Because velocity changes with direction. The object is moving around a gentle curve. The curve is not linear it is curve the direction changes a bit so obviously the velocity also changes but not much. Juts a minor change. Depends on how much curve the highway is.
