Define mechanical advantage in terms of input force and output force

1 answer:

5 0

Mechanical advantage is a measure of the force amplification achieved by using a tool, mechanical device or machine system. The device preserves the input power and simply trades off forces against movement to obtain a desired amplification in the output force. The model for this is the law of the lever. Hope this helps and please mark me as brainlest and like:)

What do high and low air pressure systems mean in terms of density?

Arada [10]

<span>There are two physical differences between Low pressure systems and </span>High pressure systems.

First, is the circulation surrounding them.

Secondly, is the atmospheric motion that they cause.

Low pressure systems circulate counter-clockwise. High pressure systems circulate clockwise. These "motions" are the building blocks in our atmosphere. They give us our weather.

A Low’s counter-clockwise circulation forces air upward (ultimately resulting in condensation, cloud formation and ultimately precipitation). A High’s clockwise circulation causes a sinking motion in the atmosphere, resulting in fair/clearer and often sunnier skies.

In certain mice, long tails (T) are dominant over short tails (t). If 2 hybrid mice mate, what will the outcome be?

yuradex [85]

Answer:

3 long tails : 1 short tail

Explanation:

This question involves a single gene coding for tail length in mice. The allele for long tail (T) is dominant over the allele for short tail (t). This means that an heterozygous mice will possess the long tail length.

According to this question, in a cross between two hybrid or heterozygote mice i.e. Tt × Tt, the following gametes will be produced by each parent:

Tt - T and t

Using these gametes in a punnet square (see attached image), the following will be produced: TT, Tt, Tt and tt.

Offsprings with genotype TT, Tt and Tt will have a LONG TAIL while genotype tt will have a SHORT TAIL. Hence, the phenotypic ratio will be 3 long tails : 1 short tail.
