Does lowering a car increase drag? Lowered vehicles are more aerodynamic. There’s less air hitting the wheels and tires (that are not streamlined shapes). This makes these cars faster. BUT, lowering a car too much will actually increase wind drag. Why is it important to reduce vehicles drag? Automotive manufacturers are placing a growing emphasis […]
Which is the strongest heart valve?
Which is the strongest heart valve? The left ventricle is the largest and strongest chamber in your heart. The left ventricle’s chamber walls are only about 1.0 to 1.3cm, but they have enough force to push blood through the aortic valve and into your body. How does the blood get around the body? Two types […]
What is the difference between dynamics and kinematics?
What is the difference between dynamics and kinematics? Traditionally, motion studies have been divided into two categories: kinematics and dynamics. Kinematics is the study of motion without regard to forces that cause it; dynamics is the study of motions that result from forces. What are kinematic properties? To describe motion, kinematics studies the trajectories of […]
Is filtered water a pure or impure substance?
Is filtered water a pure or impure substance? Water is a pure substance because it only contains one type of molecule. Pure water contains only molecules that are a combination of one oxygen atom… Is oxygen pure or impure? Air is a mixture of gasses, including nitrogen, oxygen, carbon dioxide and water vapour, as such […]
What are 5 ways to conserve energy?
What are derived units give examples?
What are derived units give examples? Answer. Definition: A derived unit is a SI unit ofmeasurement comprised of a combination of the seven base units. Examples: The SI unit of force is the derived unit newton or N. A newton is equal to 1 m. What are derived quantities give examples? Derived quantities are the […]
Why are healthy root nodules pink in Colour?
Why are healthy root nodules pink in Colour? The pink color is from leghemoglobin, a protein that carries oxygen—similar to the hemoglobin in human blood. The nitrogenase enzyme involved in N fixation is sensitive to oxygen and the leghemoglobin helps reduce oxygen concentrations in the area of the nodule where the nitrogenase enzyme is active. […]
What enzyme digests proteins?
What enzyme digests proteins? The enzyme pepsin plays an important role in the digestion of proteins by breaking down the intact protein to peptides, which are short chains of four to nine amino acids. In the duodenum, other enzymes— trypsin, elastase, and chymotrypsin—act on the peptides reducing them to smaller peptides. Where does the digestion […]
Is Jade worth money?
Is Jade worth money? As one of the most expensive gems in the world, it can sometimes be priced at millions of dollars. The second most expensive form of jade is that which exhibits a lavender hue. This color will be more expensive than other types of non-Imperial green jade, such as those with a […]
What is the relationship between osmosis and diffusion?
What is the relationship between osmosis and diffusion? Osmosis only allows solvent molecules to move freely, but diffusion allows both solvent and solute molecules to move freely. 4. Osmosis happens when molecules move from higher to lower concentrations, but diffusion happens when it is reversed. Is osmosis active or passive? Osmosis is a passive transport […]
