Why is it possible to use physical properties to separate a mixture? The substances in a mixture are separated by the differences in their physical properties, such as their particle size. The more different the properties are, the easier it is to separate the substances. What are three physical properties used to separate mixtures? Physical […]
What is the angle between the two vectors?
What is the angle between the two vectors? “Angle between two vectors is the shortest angle at which any of the two vectors is rotated about the other vector such that both of the vectors have the same direction.” Furthermore, this discussion focuses on finding the angle between two standard vectors, which means their origin […]
How can you classify mixture?
How can you classify mixture? Mixtures can be classified on the basis of particle size into three different types: solutions, suspensions, and colloids. The components of a mixture retain their own physical properties. These properties can be used to separate the components by filtering, boiling, or other physical processes. Can you still recognize salt from […]
What are the effects of gravity on the movement of objects?
What are the effects of gravity on the movement of objects? Earth’s gravity affects the motion of all the objects we see in daily life by accelerating them toward the center of the earth. Therefore, to efficiently process object motion the human visual system needs to consider gravity. How is gravity related to mass? Since […]
Why the adsorption is always exothermic?
Why the adsorption is always exothermic? The particles are attached to the surface of another medium for the reaction to take place. During this process the residual forces on the surface of adsorbent decreases which in turn decreases the surface energy. This energy appears in the form of heat, hence adsorption is exothermic in nature. […]
What is the best example of biological contamination food handlers?
What is the best example of biological contamination food handlers? a.a wedding ring that falls off of a food worker’s finger and into the salad dish. b.a can of pesticide is sprayed over the food prep area currently in-use. How do you kill pathogenic bacteria in food? Instead, rapidly reheat to 74°C (165°F) (and hold […]
How long can you live with ischemic heart disease?
How long can you live with ischemic heart disease? On average, women live longer than men with heart disease. At age 50 women can expect to live 7.9 years and men 6.7 years with heart disease. The average woman experiences heart disease onset three years older and heart attacks 4.4 years older than men. Can […]
What is an example of a cultural control of pests?
What is an example of a cultural control of pests? 4 Cultural Control. Cultural pest control refers to the manipulation of the crop production system or cultural practices to reduce or eliminate pest populations. Practices such as adjusted planting dates and crop rotations have long been recognized at the local or farm level to avoid […]
How do you cover a fruit tree with netting?
Which type of environmental scientist is most likely to study the effects of air pollution on asthma?
Which type of environmental scientist is most likely to study the effects of air pollution on asthma? the answer is an environmental physician . Which activity produces the smallest amount of greenhouse gases? Riding a bicycle produces the smallest amount of greenhouse gases. Is the concentration of atmospheric carbon dioxide is currently decreasing due to […]
