Answer:
the resulting angular speed after she pulls her hand inwards in (rad/s) is 27.02 rad/s
Explanation:
Given that :
the initial angular speed 
Initial rotational inertia 
Final angular speed 
Final rotational inertia 
According to conservation of momentum :
Initial momentum = final momentum
To rad/s ; we have:
Therefore the resulting angular speed after she pulls her hand inwards in (rad/s) = 27.02 rad/s
B. for growing vegetation and crops, because it says that, "The newly deposited soil nutrient rich and would be good." so it's good for the crops.
Answer:
What is the cloud model? It is the most recent model of the atom. Notice that instead of showing the paths of the orbit of the electrons it just shows a "cloud" around the nucleus. The cloud represents where any one electron could be at any time. This electron cloud model is based on quantum mechanics.
KE = 14175J
KE = 1/2*mass*velocity[squared]
Make sure to convert grams into kg
Here is your answer:
Matter moves against the pull of gravity during "evaporation and transpiration." Evaporation is the process when the sun heats water to it's boiling point then turns the water from a liquid to a gas. Transpiration is the process plants use to get their water. They use small pores in their leafs to suck their water up their roots to help them grow.
