Explanation

In two dimensions, a force can be resolved into two mutually perpendicular components whose vector sum is equal to the given force.

Explanation

= (80/100)*320

= (80*320)/100

= 25600/100

= 256

Explanation

 Velocity is a vector quantity

Because it requires both magnitude (speed) and direction to be fully defined.

In contrast, speed is a scalar quantity as it only has magnitude.

Explanation

Repeated extraction using portions of solvent is more efficient than using a single large portion of solvent. 

Efficiency in repeated extractions:

When you use small portions of solvent repeatedly, each extraction removes a portion of the solute from the original solution, maintaining a higher concentration gradient for subsequent extractions.

This leads to a more efficient transfer of the solute to the solvent.

Concentration gradient:

By repeatedly adding fresh solvent, you create a higher concentration difference between the solute in the original solution and the solvent, allowing for better transfer of the solute.

Single extraction limitation:

Using a single large volume of solvent may not be as efficient because the solute may not have enough time to fully transfer to the solvent due to a lower concentration gradient.
