ANS:A - an ordinary chain

The chain is used for measuring and layout of survey lines. Cloth and the metallic tape are used for measuring short offset distance while former for more accuracy. The steel tape is used for checking chain length and invar tape is used for very accurate measurements such as the base line. Invarted tape is used for measuring short offset distance while former for more accuracy. Chain is also used for the measurement of base line. Because Invar tape have low thermal expansion.

ANS:A - temperature rises.

The relative humidity of air decreases despite an increase in the absolute humidity when the temperature rises. This phenomenon occurs because warm air can hold more water vapor than cold air. When the temperature rises, the air's capacity to hold water vapor increases. If the amount of water vapor in the air remains constant (or increases at a slower rate than the air's capacity), the relative humidity decreases because the air is now capable of holding more water vapor relative to its total capacity. Therefore, when the temperature rises, the relative humidity of air decreases despite an increase in the absolute humidity.

ANS:B - 5π/2

To calculate the force exerted by the water on the right angle bend in the pipe, we need to consider the change in momentum of the water as it flows through the bend. Given:

• Flow velocity (VVV) = 1 m/s
• Internal diameter of the pipe (DDD) = 10 cm = 0.1 m
