Answer;
-A vent stack
Explanation;
-A vent stack is best described by, the vertical, upper portion above the top-most fixture through which gases and odors escape the sanitary drainage system, carrying no liquids or solids.
-The vent stack usually runs parallel with the soil/waste stack and may either extend up through the roof or connect to a stack vent. While a stack vent is the uppermost portion of a soil/waste stack that continues the pipe from above the highest connected fixture out the roof.
Carbon and chlorine atoms
Answer:
I = mgd/4π²f²
Explanation:
The period of the physical pendulum T = 1/f where f = frequency,
T = 1/f = 2π√(I/mgd) where I = moment of inertia of the physical pendulum, m =mass of pendulum, g = acceleration due to gravity and d = distance of center of mass of pendulum from pivot point.
1/f = 2π√(I/mgd)
dividing both sides by 2π, we have
1/2πf = √(I/mgd)
squaring both sides, we have
(1/2πf) = [√(I/mgd)]²
1/4π²f² = I/mgd
multiplying both sides by mgd, we have
I = mgd/4π²f²
As the molecules heat and move faster, they are moving apart. So air, like most other substances, expands when heated and contracts when cooled. Because there is more space between the molecules, the air is less dense than the surrounding matter and the hot air floats upward.
To solve this problem we will apply the concept given by the law of gravitational attraction, which properly defines gravity under the function
Here,
G = Gravitational Universal Constant
M = Mass of Earth
r = Distance between the human and the center of mass of the Earth
The acceleration due to gravity when is 4 times the mass of Earth and 3 times the radius would be given as,
The weight is defined as
So the new weight would be given as
Therefore the weight under this condition is 288.8N
