Joey should say no to drugs next time he is offered to smoke weed
Answer:
Angular acceleration will be ![18.84rad/sec^2](https://tex.z-dn.net/?f=18.84rad%2Fsec%5E2)
Explanation:
We have given that mass m = 0.18 kg
Radius r = 0.32 m
Initial angular velocity ![\omega _i=0rev/sec](https://tex.z-dn.net/?f=%5Comega%20_i%3D0rev%2Fsec)
And final angular velocity ![\omega _f=24rev/sec](https://tex.z-dn.net/?f=%5Comega%20_f%3D24rev%2Fsec)
Time is given as t = 8 sec
From equation of motion
We know that ![\omega _f=\omega _i+\alpha t](https://tex.z-dn.net/?f=%5Comega%20_f%3D%5Comega%20_i%2B%5Calpha%20t)
![24=0+\alpha \times 8](https://tex.z-dn.net/?f=24%3D0%2B%5Calpha%20%5Ctimes%208)
![\alpha =3rev/sec^2=3\times 2\times \pi rad/sec^2=18.84rad/sec^2](https://tex.z-dn.net/?f=%5Calpha%20%3D3rev%2Fsec%5E2%3D3%5Ctimes%202%5Ctimes%20%5Cpi%20rad%2Fsec%5E2%3D18.84rad%2Fsec%5E2)
So angular acceleration will be ![18.84rad/sec^2](https://tex.z-dn.net/?f=18.84rad%2Fsec%5E2)
Answer:
10.32874 m
Explanation:
= Atmospheric pressure = 101325 Pa
g = Acceleration due to gravity = 9.81 m/s²
h = Height of water
= Density of water = 1000 kg/m³
If the walls of the tube do not collapse that means that maximum pressure inside will be the atmospheric pressure
Atmospheric pressure is given by
![P_a=\rho gh\\\Rightarrow h=\dfrac{P_a}{\rho g}\\\Rightarrow h=\dfrac{101325}{1000\times 9.81}\\\Rightarrow h=10.32874\ m](https://tex.z-dn.net/?f=P_a%3D%5Crho%20gh%5C%5C%5CRightarrow%20h%3D%5Cdfrac%7BP_a%7D%7B%5Crho%20g%7D%5C%5C%5CRightarrow%20h%3D%5Cdfrac%7B101325%7D%7B1000%5Ctimes%209.81%7D%5C%5C%5CRightarrow%20h%3D10.32874%5C%20m)
The maximum height to which Superman can lift the water is 10.32874 m
On the Moon there is no atmosphere so no atmospheric pressure which means when the straw is placed in water water will not rise in the tube.
The answer is 8.
Hope I helped.
Hello,
The question states: <span>The Robinson projection map is considered very useful because...
The answer is
