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.

- A pendulum has a 0.4-m-long cord and is given a tangential velocity of 0.2 m/s toward the vertical from a position 0 = 0.3 rad. Part A Determine the equation which describes the angular motion. Express your answer in terms of the variable t. Express coefficients in radians to three significant figures.

(Figure 1) If it then falls freely (T = 0) from an essentially balanced at-rest position, determine the speed at which the corner A strikes the pad at B. The stone does not slip at its corner C as it falls. Suppose that height of the stone is L = 1.2 ft.

The battery has emf ε = 69 volts and negligible internal resistance. The inductance is L = 0.4 H and the resistances are R 1 = 12 Ω and R 2 = 9.0 Ω. Initially the switch S is open and no currents flow. Then the switch is closed. After leaving the switch closed for a very long time, it is opened again. Just after it is opened, what is the current in R 1?arrow_forward
- A capacitor with a capacitance of C = 5.95×10−5 F is charged by connecting it to a 12.5 −V battery. The capacitor is then disconnected from the battery and connected across an inductor with an inductance of L = 1.55 H . At the time 2.35×10−2 s after the connection to the inductor is made, what is the current in the inductor? At that time, how much electrical energy is stored in the inductor?arrow_forwardCan someone help me with this question. Thanks.arrow_forwardCan someone help me with this question.
