What type of movement is exhibited at the knee joint? The knee joint is a hinge type synovial joint, which mainly allows for flexion and extension (and a small degree of medial and lateral rotation). It is formed by articulations between the patella, femur and tibia. What are the 7 principles of biomechanics? Seven Principles […]
Are GMOs safe?
Are GMOs safe? The U.S. Food and Drug Administration (FDA), U.S. Environmental Protection Agency (EPA), and U.S. Department of Agriculture (USDA) ensure that GMOs are safe for human, plant, and animal health. Is GMO free the same as organic? The use of genetic engineering, or genetically modified organisms (GMOs), is prohibited in organic products. This […]
Where can we see reflections?
Is minutes a metric unit?
Will a lighter or heavier object reach terminal velocity faster?
Will a lighter or heavier object reach terminal velocity faster? heavy objects will have a higher terminal velocity than light objects. It takes a larger air resistance force to equal the weight of a heavier object. A larger air resistance force requires more speed.) Therefore, heavy objects will fall faster in air than light objects. […]
How do we affect the atmosphere?
How do we affect the atmosphere? There is substantial evidence that human activities, especially burning fossil fuels, are leading to increased levels of carbon dioxide and other greenhouse gases in the atmosphere, which in turn amplify the natural greenhouse effect, causing the temperature of the Earth’s atmosphere, ocean and land surface to increase … How […]
What happens if the ray passes through principal axis?
What happens if the ray passes through principal axis? Rule 1: When a ray of light which is parallel to the principal axis gets reflected, it passes through its focus. Rule 2: When a ray of light passes through the centre of curvature, it gets reflected back along the same path. How do you identify […]
How do rocks play an important role in formation of soil?
How do rocks play an important role in formation of soil? They help in the formation of soil through a process called weathering. The type of soil under your feet is dependent on the bedrock deep below the surface. As the bedrock breaks down, smaller pieces move to the surface and mix with the existing […]
What happens to kinetic energy when mass is constant and speed is tripled?
What happens to kinetic energy when mass is constant and speed is tripled? 1 Expert Answer a)So if the mass triples then the KE triples too. The relationship between Kinetic Energy and velocity is also directly proportional but with the square of the velocity. Hence, KE is 9 times greater. What will be the kinetic […]
