Answer:
All forms of energy are either kinetic or potential. The energy associated with motion is called kinetic energy . The energy associated with position is called potential energy . Potential energy is not "stored energy".
Explanation:
Answer is suspension.
Lets define all options.
<h3>Suspension:</h3>
In suspension the solute does not dissolve in liquid. When placed on table for some time, it will settle down at the bottom of the beaker. We can separate particles of solute easily from solvent through filtration.
<h3>Colloid:</h3>
In colloid particles of solute does not dissolve in liquid neither it is settle down. It floats through the solvent. It cannot be separated by filtration.
<h3>Solution:</h3>
In solution the particles of solute dissolve in to the solvent. We cannot identify them as separate. We cannot separate them by filtration. Salt and water solution is an example of it. Evaporation is the technique that is required to separate them.
<h3>Compound:</h3>
In compound, the two elements combine to form a new thing. Resultant/ compound have new or different properties other than its ingredients.
Now, the question was which of the following allow to settle out when sit on a table, so the answer is suspension. Suspension allows the particles to settle out when sit on a tables for some time.
Answer:
A. 3.3 m
Explanation:
Here, we have to use conservation of energy principle.
When the ball is at maximum height, the instantaneous velocity at that point is 0 m/s. So, the kinetic energy of the ball is also 0 at the maximum height. Thus, at maximum height, the energy possessed by the ball is gravitational potential energy only.
Now, when the ball reaches the ground, all the gravitational potential energy changes into kinetic energy because of the conservation of energy.
Therefore, the energy transformation can be given as:
Decrease in potential energy = Increase in Kinetic energy
Decrease in potential energy is given as:
Increase in kinetic energy is given as:
Therefore,
Now, plug in 8 for , 9.8 for and solve for height . This gives,
Therefore, the maximum height reached by the ball is 3.3 m.
