Answer:
Explanation:
Pressure is equal to the force divided by the area on which it acts. Since the smaller piston has less area so from less force also we can get more efficiency in work. And according to the Pascal's principle, in a hydraulic system, pressure exerted on a piston produces an equal increase in pressure on another piston in the system. Thus by applying little force in the smaller piston, we can get same force from larger piston too. A hydraulic machine magnifies force.
Via the half-life equation:
![A_{final}=A_{initial}(\frac{1}{2})^{\frac{t}{h}}](https://tex.z-dn.net/?f=A_%7Bfinal%7D%3DA_%7Binitial%7D%28%5Cfrac%7B1%7D%7B2%7D%29%5E%7B%5Cfrac%7Bt%7D%7Bh%7D%7D)
Where the time elapse is 11,460 year and the half-life is 5,730 years.
![A_{final}=A_{initial}(\frac{1}{2})^\frac{11460}{5730} \\\\A_{final}=A_{initial}\frac{1}{4} \\\\A_{final}=\frac{1}{4}A_{initial}](https://tex.z-dn.net/?f=A_%7Bfinal%7D%3DA_%7Binitial%7D%28%5Cfrac%7B1%7D%7B2%7D%29%5E%5Cfrac%7B11460%7D%7B5730%7D%20%5C%5C%5C%5CA_%7Bfinal%7D%3DA_%7Binitial%7D%5Cfrac%7B1%7D%7B4%7D%20%5C%5C%5C%5CA_%7Bfinal%7D%3D%5Cfrac%7B1%7D%7B4%7DA_%7Binitial%7D)
Therefore after 11,460 years the amount of carbon-14 is one fourth (1/4) of the original amount.
Answer:
Acidity
Explanation:
pH measures how acidic or basic a substance is.
If it is completely elastic, you can calculate the velocity of the second ball from the kinetic energy
<span>v1 = velocity of #1 </span>
<span>v1' = velocity of #1 after collision </span>
<span>v2' = velocity of #2 after collision. </span>
<span>kinetic energy: v1^2 = v1' ^2 + v2' ^2 (1/2 and m cancel out) </span>
<span>5^2 = 4.35^2 + v2' ^2 </span>
<span>v2 = 2.46 m/s <--- ANSWER</span>
The hull type that is best for use on ponds, small lakes and calm rivers is Flat Bottom Hull.
A flat bottomed boat is a boat with a flat bottomed, two-chined hull, which allows it to be used in shallow bodies of water, such as rivers, because it is less likely to ground. The flat hull also makes the boat more stable in calm water.
