What is the correct description of microwaves?
What is the correct description of microwaves? Microwaves are electromagnetic waves with wavelengths longer than those of terahertz (THz) wavelengths, but relatively short for radio waves. Microwaves have wavelengths approximately in the range of 30 cm (frequency = 1 GHz) to 1 mm (300 GHz). Why are microwaves good at transmitting information? Microwaves are good […]
What children learn in the sand and water area?
What children learn in the sand and water area? Cognitive Skills When children mix sand with water and compare the new consistency to dry sand, they learn the physical properties of sand and cause and effect. They also learn cause and effect as they move sand or water from one container to the next. What […]
How do metal and nonmetals react examples?
How do metal and nonmetals react examples? Give an example. Metals are electropositive elements and have a tendency to lose electron/s and acquire a positive charge. While non-metals are electronegative elements and tend to gain electron/s and acquire a negative charge. What happens when a non-metal reacts with oxygen? Non-metals react with oxygen to form […]

What are the factors affecting solar radiation? Seven factors affecting solar UV radiation Solar elevation. Where the sun sits in the sky determines the level of UV radiation reaching us. Ozone. Ozone is an important part of our atmosphere and high levels of ozone absorb higher levels of UV. Cloud cover. Ground surface reflectivity. Altitude. […]
What is the response variable in an experiment?
What is the response variable in an experiment? A responding variable is something that “responds” to changes you make in an experiment. It’s the effect or outcome in an experiment. The responding variable would be the height of the plants. In other words, the plants are responding to changes in light that you, the researcher, […]
Why does pitch change with speed?
Why does pitch change with speed? When it travels away from you, the frequency gets lower, elongating the sound wave, and making it sound lower pitched. A sounds pitch is higher when its sped up because the sounds wavelength is shorter which takes less time to hear and with the lower the wavelength is further […]
Is spraying water in your room good?
Is spraying water in your room good? Spraying water in air can increase the humidity of a room to a little extent. However normal room humidifiers use a wick like substance to absorb water from a container thereby increasing surface area so that evaporation rate increases. Humidity is nothing but water vapour present in the […]
Why does California have so many landslide problems?
Why does California have so many landslide problems? Like the northern part of the state, southern California is well known to be susceptible to landslides (see Preliminary soil-slip susceptibility maps, southwestern California – Open-File Report 2003-17). Some are triggered by earthquakes, but more frequently landslides are caused by intense and/or prolonged rainfall. What are the […]
What is the biggest number of patents held by one person?
What is the biggest number of patents held by one person? Inventor Thomas Edison is mistakenly believed to be the all-time top patent holder. And although he reputedly held 1,093 patents, there are other inventors who are even more prolific – some with almost four times the number of patents granted to Edison. How much […]
