Who started the Vietnam War? The Vietnam War had its origins in the broader Indochina wars of the 1940s and ’50s, when nationalist groups such as Ho Chi Minh’s Viet Minh, inspired by Chinese and Soviet communism, fought the colonial rule first of Japan and then of France. How many Chinese soldiers died in the […]
Which bond is the strongest?
Which bond is the strongest? Covalent bond Are metallic bonds stronger than covalent? So, in metallic bond there is actually no overlapping between any two atoms. So , we can conclude that a covalent bond is more stronger than a metallic bond. Neither ionic nor covalent bond exist in metal -how could it can be […]
Which waves move the fastest?
Which waves move the fastest? P waves travel fastest and are the first to arrive from the earthquake. In S or shear waves, rock oscillates perpendicular to the direction of wave propagation. In rock, S waves generally travel about 60% the speed of P waves, and the S wave always arrives after the P wave. […]
Why incandescent bulbs are better?
Why incandescent bulbs are better? Incandescent bulbs cost much less than their energy-efficient alternatives – mainly CFLs (compact fluorescent lamps) and LEDs (light emitting diodes). Incandescents are inefficient – 90% of the energy goes toward heat and only 10% toward light. Incandescents also don’t last as long as CFLs and LEDs. What are the disadvantages […]
What are the 4 properties of the atom?
What are the 4 properties of the atom? Typical sizes of atom and nucleus. Most of atom’s mass is in the nucleus. Constituents: protons, neutrons, electrons. Electric force holds atom together. Nuclear force holds nucleus together. Atoms, ions. Atomic number. What are three examples of properties? These properties include color, density, melting point, boiling point, […]
What is an example of emergent literacy?
What is an example of emergent literacy? Examples of emergent literacy activities include engaging in shared storybook reading, pretending to write or draw, incorporating literacy themes into play, and engaging in oral wordplay such as rhyming. Parents read to children who are very young before they can verbally participate. What are the 5 pillars of […]
What are the similarities and differences between fission and fusion?
What are the similarities and differences between fission and fusion? Both fission and fusion are nuclear reactions that produce energy, but the applications are not the same. Fission is the splitting of a heavy, unstable nucleus into two lighter nuclei, and fusion is the process where two light nuclei combine together releasing vast amounts of […]
What is the smallest electromagnetic wave?
What is the smallest electromagnetic wave? Gamma Rays Is the electromagnetic spectrum infinite? In general the frequency spectrum for Electromagnetic (e.g light, radio, etc) is continuous and thus between any two frequencies there are an uncountable infinity of possible frequencies (just as there are an uncountable number of numbers between 1 and 2). What does […]
Can you turn off a electromagnet?
Can you turn off a electromagnet? Re: Turning off electromagnet Use a relay. Wire the electromagnet to the relay’s normally closed pins, then run current through the pushbutton switch to the relay coil – when you push the switch, it’ll pull the relay the other way and the electromagnet will shut off. How do you […]
What front usually happens and is over quickly?
What front usually happens and is over quickly? Occluded Front Because cold fronts move faster, the cold front is likely to overtake the warm front. This is known as an occluded front. At an occluded front, the cold air mass from the cold front meets the cool air that was ahead of the warm front. […]
