Potassium and Chlorine is a mixture.
The water cycle is the process when water circulates from the oceans on the Earth, the atmosphere, land, this also involves rainfall and snow, sewers in rivers and streams, and then it returns to the atmosphere by evaporation and transpiration. Humans impact the water cycle by irrigation, urbanization, deforestation, and storing water in reservoirs.
Answer:
2.79 m
Explanation:
Use the static equilibrium condition, net torque actin on the system is zero.


solve for the distance of the person from the wall x

now putting the values we get

= 2.79 m
Answer:
0.336 rad/s
Explanation:
= Angular speed of the turntable = -0.2 rad/s
R = Radius of turntable = 2.9 m
I = Moment of inertia of turntable = 
M = Mass of turn table = 53 kg
= Magnitude of the runner's velocity relative to the earth = 3.6 m/s
As the momentum in the system is conserved we have

The angular velocity of the system if the runner comes to rest relative to the turntable which is the required answer is 0.336 rad/s
