Which of the following factors change when a pitch gets higher? Pitch of sound depends upon frequency , so when pitch gets higher frequency f also becomes higher , now we have ,wavelength of sound λ∝1/f (for constant speed of sound in a medium) ,hence wavelength decreases i.e. frequency and wavelength go through a change […]
What important role does the mesosphere play?
What important role does the mesosphere play? Chemicals and the Environment It is the coldest place on Earth and has a temperature on the order of − 85°C (− 120°F). Just below the mesopause, the air is so cold that even the very scarce water vapor at this altitude can be sublimated into polar-mesospheric noctilucent […]

Why Acid rain is harmful for us?
Why Acid rain is harmful for us? The pollution that causes acid rain can also create tiny particles. When these particles get into people’s lungs, they can cause health problems, or can make existing health problems worse. This ground-level ozone causes respiratory problems, like pneumonia and bronchitis, and can even cause permanent lung damage. Can […]
Where is 0 hours right ascension?
Where is 0 hours right ascension? In the sky, 0h (“zero hours”) right ascension is defined as where the plane of the Earth’s orbit around the Sun (the ecliptic) crosses the celestial equator in Pisces. This point is called, for historical reasons, the First Point of Aries. What month is the sun highest in the […]

What is the main difference between passive and active transport?
What is the main difference between passive and active transport? There are two major ways that molecules can be moved across a membrane, and the distinction has to do with whether or not cell energy is used. Passive mechanisms like diffusion use no energy, while active transport requires energy to get done. What are the […]
Does high pressure mean low temperature?
Does high pressure mean low temperature? The positions of high and low pressure centers can greatly influence a forecast. Fair weather generally accompanies a high pressure center and winds flow clockwise around a high. This means that winds on the back (western) side of the high are generally from a southerly direction and typically mean […]
