Are kinematic equations valid when acceleration is zero? The equations can be utilized for any motion that can be described as being either a constant velocity motion (an acceleration of 0 m/s/s) or a constant acceleration motion. They can never be used over any time period during which the acceleration is changing. Each of the […]

How do you find the horizontal asymptote of a graph?
How do you find the horizontal asymptote of a graph? The horizontal asymptote of a rational function can be determined by looking at the degrees of the numerator and denominator. Degree of numerator is less than degree of denominator: horizontal asymptote at y = 0. Degree of numerator is greater than degree of denominator by […]

What are the two processes of erosion?
What are the two processes of erosion? Erosional processes along coastlines include: (1) the direct effects of hydraulic action, wedging, and cavitation by waves; (2) abrasion (corrasion), using sand, gravel, and larger rock fragments as tools; (3) attrition of the rock particles themselves during this abrasive action; (4) salt weathering or fretting; (5) … What […]
What is the first organ to receive oxygenated blood?
What is the first organ to receive oxygenated blood? Blood enters the right atrium and passes through the right ventricle. The right ventricle pumps the blood to the lungs where it becomes oxygenated. The oxygenated blood is brought back to the heart by the pulmonary veins which enter the left atrium. From the left atrium […]

Which metal expands the most when heated?
Which metal expands the most when heated? potassium metal Does heat shrink or expand metal? What does heat do to metal? The expansion (or contraction) of any material is due to the kinetic energy of its atoms. When a material is heated, the increase in energy causes the atoms and molecules to move more and […]
Which country time zone is first?
Which country time zone is first? IDL is another imaginary line that passes through the middle of the Pacific Ocean and determines where you cross from one day to the next.
