Answer:
Sugar
Explanation:
Nisha's list: Amol's list
Jute Vinegar
Wood Lemon juice
Rubber Cooking soda
Nisha's list is made up of things that can be derived from plants. From the list given, oil, sugar and cotton can also be obtained from plants.
Most plant materials are organic matter.
Amol's list is made up of things that can dissolve in water. Sugar and table salt can also be dissolved in water.
Water is able to dissolve these materials because they are polar compounds. One rule of solubility is that like dissolves like.
New list:
Nisha's list: Amol's list
Jute Vinegar
Wood Lemon juice
Rubber Cooking soda
Sugar Sugar
Only sugar from the list can be added to both lists. It can be obtained from plant and can also dissolve in water.
The value of mass m = 0.506kg
Initial frequency = 0.78Hz
additional mass = 730 g = 0.73kg
New frequency = 0.65 Hz
F = 1/2π 
0.78 = 1/2π 
additional mass,
0.65 = 1/2π 
1.44 = k/m / k/m+0.73
1.44 = m+0.73 / m
1.44m -m = 0.73
1.44m = 0.73
mass m = 0.506kg
a measurement used in physics to express the inertia, a quality that all matter has in common. Effectively, it is the resistance a body of matter offers to a change in its speed or position as a result of the application of a force. The change caused by an applied force is proportional to the mass of the body. The kilograms is the measure of mass in the International System of Units (SI). Its definition is based on the Planck constant, which is set at 6.62607015 1034 joule second. The unit of energy known as a joule is one kilogramme times one square metre per second. The kilogramme is determined by precise measurements of Planck's constant, while the second and metre are already defined in terms of other physical constants.

Answer:
(C)Direct kick
Explanation:
In a game of soccer (foot-ball) there are lots of rules involved in the game and there is penalty for each of the rules violated. Some of the rules include penalty kick, free kick, throw in, goal kick etc.
Free kick is of two types; direct kick and indirect kick.
Direct kick is awarded when a player outside 18 yards box violently or dangerously charges a opponent.
Indirect kick can be awarded when a goalkeeper inside 18 yards box commits certain offenses.
Therefore, the correction option is (C)Direct kick
