A20n stone rests on a table. what is the force the table exerts on the stone? in what direction?

The force exerted by table on the stone will be 20 N in upward direction.

Explanation:

Balanced forces are defined as the forces which gets cancelled out when equal forces are acting in the opposite direction. The net force on the system comes out to be 0.

Unbalanced forces are defined as the forces which does not get cancelled out because unequal forces act on the system in opposite direction. The motion of the object is in the direction of net force.

According to the question:

The force exerted by the stone on the table in downward direction = 20 N

Net force acting on the stone = 0 N (because it is at rest)

So, the force exerted by the table on the stone will be same, which is equal to 20 N but in upward direction.

Hence, the force exerted by the table on the stone is 20 N in upward direction.

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
