Explain a wedge and give 3 examples.

A wedge is basically an incline plane. Often portable used for many purposes

Explanation: A wedge is a double inclined plane such that the two sloping surfaces taper to form either a sharp edge or a pointed edge. For example, a knife, an axe etc.

In a few cases, the number of inclined planes used can be more than two as well. In such cases, the sloping surfaces generally taper to form either a very sharp or a pointed edge to split or pierce materials. For example, pins, nails etc.

The front end of a boat is shaped like a wedge so that it can easily cut across the flowing water.

The wedge works on the principle of an inclined plane.

The Door Stop Is an example of one,

A Knife is a very thin wedge because it slices through objects

Chisels are used to dig into stone and chip away at it to create sculptures.

hey, i believe your answer would be d. sugar ribose and the base uracil. i believe this is the answer, because rna consists of sugar ribose, adenine, guanine, cytosine, and uracil.

your first option is incorrect, because that's dna. where it consists of sugar deoxyribose, adenine, guanine, cytosine and thymine.

your second option is also incorrect, this is because sugar deoxyribose is in dna, and uracil is in rna. these two do not make sense together.

your third option being incorrect, because sugar ribose is in rna, but not the base of thymine. rna consists of uracil, not thymine.

lastly your fourth option being correct! this answer is correct, because both sugar ribose, and the base uracil are in rna! ~

answer is d. sugar ribose and the base uracil.
