For Pascal's law, the pressure is transmitted with equal intensity to every part of the fluid:
![p_1 = p_2](https://tex.z-dn.net/?f=p_1%20%3D%20p_2)
which becomes
![\frac{F_1}{A_1}= \frac{F_2}{A_2}](https://tex.z-dn.net/?f=%20%5Cfrac%7BF_1%7D%7BA_1%7D%3D%20%5Cfrac%7BF_2%7D%7BA_2%7D%20%20)
where
![F_1=3600 N](https://tex.z-dn.net/?f=F_1%3D3600%20N)
is the force on the first piston
![A_1=0.030 m^2](https://tex.z-dn.net/?f=A_1%3D0.030%20m%5E2)
is the area of the first piston
![F_2](https://tex.z-dn.net/?f=F_2)
is the force on the second piston
![A_2=0.015 m^2](https://tex.z-dn.net/?f=A_2%3D0.015%20m%5E2)
is the area of the second piston
If we rearrange the equation and we use these data, we can find the intensity of the force on the second piston:
Gravity pulls to the centre of the earth. A ship floats in water because the water pushing it up (upthrust) is equal to the force<span> of gravity (weight) pulling it </span>down<span>. Friction also occurs when objects move through air. This is </span>called<span>air resistance.</span>
Answer:
Explanation:
It is given that two identical masses is attached to the either end of the spring
with spring constant k
angular frequency of the system is given by
![\omega _n=\sqrt{\frac{k}{m_{equivalent}}}](https://tex.z-dn.net/?f=%5Comega%20_n%3D%5Csqrt%7B%5Cfrac%7Bk%7D%7Bm_%7Bequivalent%7D%7D%7D)
![m_{equivalent}=\frac{m_1m_2}{m_1+m_2}](https://tex.z-dn.net/?f=m_%7Bequivalent%7D%3D%5Cfrac%7Bm_1m_2%7D%7Bm_1%2Bm_2%7D)
here ![m_1=m_2=m](https://tex.z-dn.net/?f=m_1%3Dm_2%3Dm)
![m_{eq}=\frac{m\times m}{m+m}](https://tex.z-dn.net/?f=m_%7Beq%7D%3D%5Cfrac%7Bm%5Ctimes%20m%7D%7Bm%2Bm%7D)
![m_{eq}=\frac{m^2}{2m}](https://tex.z-dn.net/?f=m_%7Beq%7D%3D%5Cfrac%7Bm%5E2%7D%7B2m%7D)
![m_{eq}=\frac{m}{2}](https://tex.z-dn.net/?f=m_%7Beq%7D%3D%5Cfrac%7Bm%7D%7B2%7D)
Thus ![\omega _n=\sqrt{\frac{k}{\frac{m}{2}}}](https://tex.z-dn.net/?f=%5Comega%20_n%3D%5Csqrt%7B%5Cfrac%7Bk%7D%7B%5Cfrac%7Bm%7D%7B2%7D%7D%7D)
![\omega _n=\sqrt{\frac{2k}{m}}](https://tex.z-dn.net/?f=%5Comega%20_n%3D%5Csqrt%7B%5Cfrac%7B2k%7D%7Bm%7D%7D)
It doesn't matter which man you ask. The answer you get will tell you
where the million $ is, although you still won't know whether the man
you asked was the liar or the truther. (But who cares about that. Right ?)
Pick either 'guard',and ask him:
"<em> IF</em> I were to ask you 'Is the money behind your door ?', would you say 'Yes' ? "

a proton and neutron weigh about the same, while an electron is about 1/2000 of the weight of either a proton or neutron
