To Describe: The cohesive force shown in the figure.

Explanation of Solution
Introduction:
Cohesive force is nothing but the property of molecules that sticks together. They are a mutually attractive force in nature.
Cohesive forces in a liquid pull together the molecules in the liquid drop to the spherical shape by force. If the cohesive forces in the liquid are stronger, then the liquid drop’s shape will be closer to being spherical.
The drop of mercury is most spherical, and the drop of acetone is least spherical in size. The spherical shape also decreases from water to ethanol. So mercury's cohesive force is strongest followed by those in water and ethanol. And in acetone, the unified forces are less powerful.

- Required information Two speakers vibrate in phase with each other at 523 Hz. At certain points in the room, the sound waves from the two speakers interfere destructively. One such point is 1.45 m from speaker #1 and is between 2.00 m and 4.00 m from speaker #2. The speed of sound in air is 343 m/s. How far is this point from speaker #2? marrow_forwarda) Consider the following function, where A is a constant. y(x,t) = A(x — vt). Can this represent a wave that travels along? Explain. b) Which of the following are possible traveling waves, provide your reasoning and give the velocity of the wave if it can be a traveling wave. e-(a²x²+b²²-2abtx b.1) y(x,t) b.2) y(x,t) = = A sin(ax² - bt²). 2 b.3) y(x,t) = A sin 2π (+) b.4) y(x,t) = A cos² 2π(t-x). b.5) y(x,t) = A cos wt sin(kx - wt)arrow_forwardThe capacitor in (Figure 1) is initially uncharged.
