Describe a procedure to separate a mixture of sugar, black pepper, and pebbles.

Answer : The procedure to separate the mixture of sugar, black pepper and pebbles would require physical methods.

First step is to pass the mixture through a grid that traps the pebbles in it and allows the passage of black pepper and sugar from it or alternatively, physically hand-picking up the pebbles can also be done.

Next step is to add water to the mixture to the sugar and black pepper, stir this solution until all the sugar dissolves in the water. Then pass this solution from a filter paper and collect the filtrate in a beaker.

The residue would contain the black pepper on it, it can be dried after separation.

To obtain the sugar which is dissolved in water, one can evaporate the water in it and get the sugar at the bottom of the beaker.

the tides are influenced by both the moon and the sun, it's easy to see that when the sun lines up with the moon and the earth, as during a new moon or full moon, the tidal effect is increased. these are known as spring tides, named not for the season, but for the fact that the water "springs" higher than normal. on the other hand, if the sun and the moon are 90 degrees apart in relation to an observer on earth as during the first quarter moon or third quarter moon, then high tides are not as high as they normally would be. this is because despite its greater distance, the sun's mass allows it to exert enough gravitational force on the oceans that it can negate some of the effects of the moon's pull. this phenomenon of lower high tides is called a neap tide. if you need more information on this topic visit moonconnection.com.
