Where in your body do mechanical and chemical digestion occur? Digestion is a process that converts nutrients in ingested food into forms that can be absorbed by the gastrointestinal tract. Proper digestion requires both mechanical and chemical digestion and occurs in the oral cavity, stomach, and small intestine. What mechanical and chemical digestion occurs in […]

What happen when you perform a cardiovascular activity?
What happen when you perform a cardiovascular activity? Cardiovascular exercise is any vigorous activity that increases heart rate and respiration and raises oxygen and blood flow throughout the body while using large muscle groups of the body repetitively and rhythmically. What is the relationship between physical activity and cardiovascular fitness? What is the connection between […]
Why force is directly proportional to pressure?
Why force is directly proportional to pressure? From equation (1) it is evident that as force increases, pressure also increases and as force decreases pressure also decreases since force is in the numerator. Or pressure is directly proportional to the applied force. Whereas as the area increases, the pressure decreases. i.e. it increases with the […]

What is its effect to the environment?
What is its effect to the environment? Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water. Can humans improve their environment if so how? Avoid Taking Cars or Carpool When Possible. Cars are harmful […]
Are superconductors 100% efficient?
Are superconductors 100% efficient? A superconducting material has absolutely zero electrical resistance, not just some small amount. If conductor resistance could be eliminated entirely, there would be no power losses or inefficiencies in electric power systems due to stray resistances. Electric motors could be made almost perfectly (100%) efficient. Which metal is superconductor? But at […]

What electromagnetic waves are blocked by the atmosphere?
What electromagnetic waves are blocked by the atmosphere? In contrast, our atmosphere blocks most ultraviolet light (UV) and all X-rays and gamma-rays from reaching the surface of Earth. Because of this, astronomers can only study these kinds of light using detectors mounted on weather balloons, in rockets, or in Earth-orbiting satellites. What is an artificial […]
