What is constant acceleration equal to? If the velocity of the particle changes at a constant rate, then this rate is called the constant acceleration. For example, if the velocity of a particle moving in a straight line changes uniformly (at a constant rate of change) from 2 m/s to 5 m/s over one second, […]

Is blood in your body blue until it touches oxygen? Hemoglobin bound to oxygen absorbs blue-green light, which means that it reflects red-orange light into our eyes, appearing red. That’s why blood turns bright cherry red when oxygen binds to its iron. But this is wrong; human blood is never blue. The bluish color of […]

Can you contract the coronavirus disease by touching a surface? Like the common cold, coronavirus infection usually occurs through close contact with a person with novel coronavirus via cough and sneezes or hand contact. A person can also catch the virus by touching contaminated surfaces if they do not wash their hands. Are tobacco users […]

What is complete sentence and examples? So, you might say, “Claire walks her dog.” In this complete sentence, “Claire” is the subject, “walks” is the verb, and “dog” is the object. (“Her” is simply a required pronoun in this example.) Beyond these basic elements, a complete sentence must also express a complete thought. What are […]

Why does the coil spin in a simple motor? The coil of wire is mounted in the gap between the two magnets. The split rings make electrical contact with the coil and reverse the current every half turn. When an electric current flows through the coil, a force is exerted on the coil, causing it […]

Will I gain weight if I overeat for a week? What you eat — or overeat — does not instantly turn into weight gain. How much you eat over the course of a few days or week, however, can result in weight gain. How much fat can you gain in one day? If you’re typically […]

What is the formula of potential difference between two points? The potential difference between two points ΔV is often called the voltage and is given by ΔV=VB−VA=ΔPEq Δ V = V B − V A = Δ PE q . The equation for the electric potential due to a point charge is V=kQr V = […]

What are the four measures of a wavelength? The wavelength λ is the distance between two adjacent crests (or troughs) and is given in meters….1.2 The measures of a wave: velocity, amplitude, wavelength and frequency. c = λ = λ f T What are 2 ways to measure wavelength? Terms in this set (5) What […]

How do you tell if a compound is a cation or anion? Key Points The electronic configuration of many ions is that of the closest noble gas to them in the periodic table. An anion is an ion that has gained one or more electrons, acquiring a negative charge. A cation is an ion that […]
