The process of osmosis, the salts and sugars pull water into your bloodstream and speed up-----.

Read the given statements and select the correct option. Statement 1 : Reforestation is the process of restoring a forest that once existed but was removed at some point of time in the past. Statement 2: Reforestation may occur naturally in a deforested area, however it can be speeded up by planting trees with due consideration to biodiversity that earlier existed in that area.

The process of eveporation is not a good technique to separate salt from sea water. Give reason.

________ are substances that speed up the process of a chemical change and it will not under go any change during the course of the reaction

Water leaks out from an open tank through a hole of area 2mm^2 in the bottom. Suppose water is filled up to a height of 80 cm and the area of cross section of the tankis 0.4 m^2 . The pressure at the open surface and the hole are equal to the atmospheric pressure. Neglect the small velocity of the water near the open surface in the tank. a. Find the initial speed of water coming out of the hole. b. Findteh speed of water coming out when half of water has leaked out. c. Find the volume of water leaked out during a time interval dt after the height remained is h. Thus find the decrease in height dh in term of h and dt. d. From the result of part c. find the time required for half of the water to leak out.

Observe the picture containing a kettle and note that it has salt water in it and answer the following questions : (a) What is name of the process that is done to the kettle?

A motor boat heads upstream a distance of 24 km in a river whose current is running at 3 km per hour. The trip up and back takes 6 hours. Assuming that the motor boat maintained a constant speed, what was its speed in still water?

Read the paragraph and answer the following question: You must be knowing about the high and low tides that occur regularly in the sea. The level of the sea water at any given location along sea shore increases and decreases twice a day at regular intervals. High and low tides occur at different times at places. The level of water in sea changes because of the gravitational force exerted by the moon. Water directly under the moon gets pulled towards the moon and the level of water there goes up causing high tide at that place. At two places on the earth at 90^(@) from the place of high tide, the level of water is minimum and low tides occur there. How does sea level changed?

A U-tube having unequal arm-lengths has water in it. A tuning fork of frequency 440 Hz can set up the air in the shorter arm in its fundamental mode of vibration and the same tuning fork can set up the air in the longer arm in its first overtone vibration. Find the length of the air columns Neglect any end effect and assume that the speed of sound in air = 330 ms^-1
