Why do minerals cleave only in specific directions?

Why do minerals cleave only in specific directions?
by

1 Answer

Answer :

Cleavage depends on the arrangement and bonding of molecules. Minerals tend to split among the planes of weak bonds between their atoms. In specifying the cleavage properties of a mineral, scientists count the number of nonparallel planes of cleavage, and the angle between those cleavage planes.

Why do some directions for medicine read, “Only apply to infected area”?

Description : Why do some directions for medicine read, “Only apply to infected area”?

Last Answer : Because some idiot probably ate it or stuck it in an orifice it wasn’t designed for and got sick so they ended up suing the company that made the medicine. To protect themselves, they put this disclaimer on their packages.

Will existing iphone 3G users get turn by turn directions/compass features with 3.0 softare, or are those features only for iphone 3g S?

Description : Will existing iphone 3G users get turn by turn directions/compass features with 3.0 softare, or are those features only for iphone 3g S?

Last Answer : The old 3G Doesn’t have the magnetometer that the new 3GS does. You definitely won’t get the compass feature, but I’m not sure about the turn-by-turn directions. It seems unlikely to me, since having your exact bearings is pretty vital to knowing which way to turn.

Not far outside the town of Pottsville, a railroad track runs through a tunnel in a hillside. There’s only one track, and the tunnel is wide enough for only one train. But one day, two trains went into the tunnel from opposite directions. Each train entered the tunnel exactly at eight o’clock. Three minutes later, each train came out at the opposite ends of the tunnel. Yet, there was no collision! How was this possible? -Riddles

A traveler, on his way to Miami, reaches a road junction, where he can turn left or right. He knows that only one of the two roads leads to Miami, but unfortunately, he does not know which one. Fortunately, he sees two twin-brothers standing at the road junction, and he decides to ask them for directions. The traveler knows that one of the two brothers always tells the truth and the other one always lies. Unfortunately, he does not know which one always tells the truth and which one always lies. How can the traveler find out the way to Miami by asking just one question to one of the two brothers? -Riddles

Two vectors are said to be equal if – (1) only their magnitudes are same (2) only their directions are same (3) both magnitude and direction are same (4) magnitudes are same but directions are opposite

Description : Two vectors are said to be equal if – (1) only their magnitudes are same (2) only their directions are same (3) both magnitude and direction are same (4) magnitudes are same but directions are opposite

Last Answer : (3) both magnitude and direction are same Explanation: If the magnitude as well as direction of two vectors are equal, then they are known as equal vectors. In other words, two vectors are ... headed towards the same direction. For two equal vectors, their directed line segments must be parallel.
