Answer:
B. The force of motion is different when a strong or a weak force is applied to the ball.
Explanation:
If you kick the ball the with stronger force, the ball will travel further than it would if weaker force were to be applied to the ball. In other words, if you softly kicked a ball, it wouldn't go as far as it would if you kicked the ball hard/with more force.
Answer:
T = 10 s
Explanation:
First, we need to find the frequency of the object as follows:
where,
Speed = Angular Speed = 6 rpm
Therefore,
Now, for time period (T):
<u>T = 10 s</u>
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:
When the bar magnet is withdrawn from inside the coil, again an induced current is setup in the coil due to change of magnetic field through it. As a result galvanometer gives a deflection in the reverse direction
When the motion of an object changes, the forces are unbalanced. Balanced forces are equal in size and opposite in direction. ... When the forces on an object are equal and in opposite directions, the forces are balanced, and there is no change in motion.
