What is the importance of state government? State and local governments exercise important functions in the United States. They plan and pay for most roads, run public schools, provide water, organize police and fire services, establish zoning regulations, license professions, and arrange elections for their citizens. What are 5 responsibilities of the state government? States […]

How is pressure created? Pressure is defined to be the amount of force exerted per area. So to create a large amount of pressure, you can either exert a large force or exert a force over a small area (or do both). In other words, you might be safe lying on a bed of nails […]

Can I bring a razor in my carry on? Disposable razors, replacement blades, and electric razors can go in either your carry-on or checked baggage; if you have a safety or straight razor, you can pack it in your carry-on — but you must remove the blades first and pack them in one of your […]

Is boiled water healthier than filtered water? If you don’t have safe bottled water, you should boil your water to make it safe to drink. Boiling is the surest method to kill disease-causing organisms, including viruses, bacteria, and parasites. Is most well water safe to drink? Most groundwater is dubbed safe, but people should have […]

What is the difference between TE and TM waves? The difference between TE and TM mode is that TE stands for transverse electric mode while TM stands for transverse magnetic mode. TE mode is also known as H mode as there is only a magnetic field along the direction of propagation. Why TEM wave is […]

What happens when a warm air mass replaces a cold air mass? Warm Front: transition zone from cold air to warm air. A warm front is defined as the transition zone where a warm air mass is replacing a cold air mass. Warm fronts generally move from southwest to northeast and the air behind a […]

Does flow rate change with pipe diameter? Pipe Diameter (D): The larger the pipe diameter is, the slower the flow velocity will be. Optimal flow rate can be maintained without increasing the velocity, if a larger pipe is specified. Does pressure decrease with pipe diameter? When the diameter of the downstream pipe decreases, the pressure […]

What does it take to move an electron from a lower state to a higher state? When an electron absorbs energy, it jumps to a higher orbital. This is called an excited state. An electron in an excited state can release energy and ‘fall’ to a lower state. The electron can absorb one quantum of […]

Which one is the strongest bond? Cl−F bond is strongest among all. What is most likely to bond with fluorine? lithium What happens when two fluorine atoms bond? In Figure 2, two fluorine atoms can each fill their valence orbitals with eight electrons if they approach each other to share their single electrons. The two […]

What do S and P waves have in common? P (Primary) and S (Secondary) Waves are Body Waves often associated with Seismic Waves as in Earthquakes. Both Body Waves and Surfaces waves comprise an earthquake, but the body waves arrive first. Primary are first, And Secondary are, well, second of course. What type of rhythm […]
