Explain how a wedge changes an input force

Chemistry
1 answer:
Fynjy0 [20]3 years ago
5 0
It is the ratio of the output force to the input force. A wedge applies more force to the object than the user applies to the wedge, so the mechanical advantage of a wedge is greater than 1. A longer, thinner wedge has a greater mechanical advantage than shorter, wider wedge.

Draw the alcohol that is the product of the reduction of 3-methylpentanal.
natali 33 [55]

Answer: The product from the reduction reaction is

CH3-CH2-CH(CH3)-CH2-CH2OH

IUPAC name; 3- Methylpentan-1-ol

Explanation:

Since oxidation is simply the addition of oxygen to a compound and reduction is likewise the addition of hydrogen to a compound.

Therefore, hydrogen is added onto the carbon atom adjacent to oxygen in 3- methyl pentanal

CH3 CH2 CHCH3 CH2 CHO thereby -CHO( aldehyde functional group) are reduced to CH2OH ( Primary alcohol) which gives;

3-methylpenta-1-ol .

The structure of the product is:

CH3-CH2-CH(CH3)-CH2-CH2OH

N a football game, two players tackle each other so hard that they both fly in opposite directions after they hit each other. �W
evablogger [386]

Answer:

Newton's Third Law

Explanation:

Newton's Third Law stipulates that for every action there is an equal and opposite reaction.

So when the two players are tackling they exert a force on each other.

If player 1 tackles (exerts a force) player 2,  player 2 will exert an equal and opposite reaction on player 1 as stated in Newton's Third Law.

Therefore when they tackle each other so hard they both experience reaction forces so powerful that they fly in opposite directions.

Thus this is an example of the Newton's Third Law.
