The time taken by the entire water to drip from upper vessel to lower vessel was used for measuring time intervals.

In the morning, the Sun appears low in the sky; objects cast long shadows. As Earth rotates, the Sun appears higher in the sky, and the shadows get shorter. At noon, with the Sun overhead, objects cast short shadows or no shadow at all.
Stand outside in a clear spot so your shadow projects on the ground rather than a wall. Have a helper measure the length of your shadow. Your shadow will be longer in the beginning and end of the day, and shorter toward the middle. Look up your shadow's length on the Personal Sundial chart to determine the time.

No,we cannot use the same fuse in a geyser and a television set as the electricity rate required by both is different. A geyser needs more electricity than a television set as it uses electricity to heat water while a television set needs electricity to put pixels on the screen. Hence we need a fuse of a higher melting point for a geyser and a fuse of a lower melting point for a television set.

Blood is responsible for the following body functions:
Fluid Connective Tissue: Blood is a fluid connective tissue composed of 55% plasma and 45% formed elements including WBCs, RBCs, and platelets. Since these living cells are suspended in plasma, blood is known as a fluid connective tissue and not just fluid.
Provides oxygen to the cells: Blood absorbs oxygen from the lungs and transports it to different cells of the body. The waste carbon dioxide moves from the lungs to the blood and is exhaled.
Transports Hormone and Nutrients: The digested nutrients such as glucose, vitamins, minerals, and proteins are absorbed into the blood through the capillaries in the villi lining the small intestine.
The hormones secreted by the endocrine glands are also transported by the blood to different organs and tissues.
Homeostasis: Blood helps to maintain the internal body temperature by absorbing or releasing heat. When the blood vessels react to outside organisms and changes in internal temperature, they expand and contract. This moves the blood and heat closer to or away from the skin surface.
Blood Clotting at Site of Injury : The platelets help in the clotting of blood at the site of injury. The platelets form a clump at the damaged area. Fibrins are formed to complete the clot.
Transport of waste to the Kidney and Liver: Blood enters the kidney where it is filtered to remove nitrogenous waste out of the blood plasma. The toxins from the blood are also removed by the liver.
Protection of body against pathogens: The White Blood Cells fight against infections. They multiply during the infections.
