Explanation: they are so many ocean water in the world
Answer:
![4.7\cdot 10^6 Pa](https://tex.z-dn.net/?f=4.7%5Ccdot%2010%5E6%20Pa)
Explanation:
The total force exerted by the man on the chair is equal to his weight:
![F=W=mg](https://tex.z-dn.net/?f=F%3DW%3Dmg)
where m=95.0 kg is the man's mass and g=9.8 m/s^2. Substituting,
![F=(95.0 kg)(9.8 m/s^2)=931 N](https://tex.z-dn.net/?f=F%3D%2895.0%20kg%29%289.8%20m%2Fs%5E2%29%3D931%20N)
Since there are 4 legs, we can assume that the force is equally distributed over the 4 legs; so the force supported by each leg is
![F=\frac{931 N}{4}=232.8 N](https://tex.z-dn.net/?f=F%3D%5Cfrac%7B931%20N%7D%7B4%7D%3D232.8%20N)
The radius of each leg is
, so the area of each leg is
![A=\pi r^2 = \pi (0.004 m)^2=5\cdot 10^{-5} m^2](https://tex.z-dn.net/?f=A%3D%5Cpi%20r%5E2%20%3D%20%5Cpi%20%280.004%20m%29%5E2%3D5%5Ccdot%2010%5E%7B-5%7D%20m%5E2)
And the pressure exerted on each leg is equal to the ratio between the force supported by each leg and the area:
![p=\frac{F}{A}=\frac{232.8 N}{5\cdot 10^{-5} m^2}=4.7\cdot 10^6 Pa](https://tex.z-dn.net/?f=p%3D%5Cfrac%7BF%7D%7BA%7D%3D%5Cfrac%7B232.8%20N%7D%7B5%5Ccdot%2010%5E%7B-5%7D%20m%5E2%7D%3D4.7%5Ccdot%2010%5E6%20Pa)
Answer:
the helis speed increased its speed by 35 m/s. Unless you are asking me what was the speed per second. if you were asking me for the speed per second then that would be a different answer
Explanation:
Answer:
Hydrogen peroxides are known to be an active ingredient in hair dyes. Hydrogen peroxide is a damaging chemical although it has been added in diluted amounts in hair dyes. Some hair dye companies have already started looking for alternatives for hydrogen peroxide to use in their products, concerning the damaging effects of the chemical.
Hydrogen peroxide can cause hair loss, dermatitis and scalp burns.
Concerning the harmful chemicals in dyes, many people consider it is best to use henna if you really want a colour change for your hair.
