Answer:
there are .1 cm in a mm so you would do 88 times .1 to get 8.8
Answer:
D.Tetrahedral
Explanation:
The central atom has 0 lone pair and 4 bond pairs. Hybridization is sp³. The geometry is tetrahedral which has an angle of 109.5°.
According to VSEPR theory, each molecule arranges itself such that it faces minimum repulsion and the given molecule is of type .
Therefore the answer will be D.
D.Tetrahedral
Answer:
Actually, 4.5cm could be marked at the darker line between 4&5 in the ruler,
Or you can count 5 lines from 4 towards 5(towards your right) and the fifth line you count will be 4.5 and you can mark that as the asnwer
The answer is B 1,500 meters since 1 kilometer to meters is 1,000 and u add the 500
Answer:
<em>A) it transforms a small force acting over a large distance into a large force acting over a small distance.</em>
Explanation:
The hydraulic lever works based on Pascal's law of transmission of pressure through a fluid. In the hydraulic lever, the pressure transmitted is the same.
Pressure transmitted P = F/A
where F is the force applied
and A is the area over which the force is applied.
This pressure can be manipulated on the input end as a small force applied over a small area, and then be transmitted to the output end as a large force over a large area.
F/A = f/a
where the left side of the equation is for the output, and the right side is for the input.
The volume of the displaced fluid will be the same on both ends of the hydraulic lever. Since we know that
volume V = (area A) x (distance d)
this means that the the piston on the input smaller area of the hydraulic lever will travel a greater distance, while the piston on the larger output area of the lever will travel a small distance.
From all these, we can see that the advantage of a hydraulic lever is that it transforms a small force acting over a large distance into a large force acting over a small distance.
