What is the formula for displacement? Displacement (s) of an object equals, velocity (u) times time (t), plus ½ times acceleration (a) times time squared (t2). What is the area under displacement time graph? Important: The area between a velocity-time graph and the `time’ axis gives the displacement of the object. The slope is the […]

What is the wavelength of the first harmonic?
What is the wavelength of the first harmonic? For the first harmonic, the length of the string is equivalent to one-half of a wavelength. If the string is 1.2 meters long, then one-half of a wavelength is 1.2 meters long. The full wavelength is 2.4 meters long. What is a harmonic wave? A harmonic is […]
Which state of matter has the greatest amount of kinetic energy?
Which state of matter has the greatest amount of kinetic energy? Energy and State of Matter Particles has the highest kinetic energy when they are in the gaseous state. Kinetic energy is related to heat (also called thermal energy). Raising the temperature results in an increase of its kinetic energy. What molecule has the most […]

Can we see water vapor?
Can we see water vapor? Gaseous water, or water vapor, isn’t something you can see, but it’s part of the air around you. Under normal circumstances, water vapor enters the atmosphere through evaporation and leaves by condensation (rain, snow, etc.). Water vapor also enters the atmosphere by a process called sublimation. Does water vapor contain […]
What does heat do to MS?
What does heat do to MS? MS causes nerves to lose their myelin sheath, making them more vulnerable to heat and temperature changes. Heat exposure can cause or heighten fatigue, numbness, blurry vision, tremor, confusion, imbalance, and weakness. This is a pseudo-exacerbation as symptoms typically dissipate once the body is cooled. Does MS get worse […]
