Which drum makes a sound that fades away faster? Fading away of sound waves depends on the wavelength of the sound. The one that has a loud sound with high frequency will have a brighter sound. While the more mellow one will have the bassier sound. Therefore, the sound with a more mellow sound will […]

How often should I run intervals? Watson suggests keeping the frequency at once per week for both and try to — at the very least — leave at least two days between intervals and long runs. “Otherwise, you may overdo it and suffer from burnout, fatigue or injury,” he says. “This will also allow your […]

How much water do I put in pressure cooker for meat? When you use a pressure cooker, you need to have enough liquid in the pot for it to come up to pressure and cook the food properly. The rule of liquids in pressure cooking is to always add at least 1 cup of liquid […]

How do you know charges of elements? There are four ways to find the charge of an element: Use the periodic table. The usual charge of an element is common to its group. Use a chart. For a single atom, the charge is the number of protons minus the number of electrons. Find the charge […]

What is Sir effect? SIR effect finds immense use in explaining Stability of carbocation, acidity and basicity of organic compounds: For example(1): Ortho substituted Benzoic acid is more acidic then meta or para substituted benzoic acid irrespective of nature of group (electron donating group or electron withdrawing group) Is ortho effect and Sir effect same? […]

Is veal a good substitute for lamb? Lamb, goat, ox. In some countries, it’s common to substitute veal with lamb meat. However, lamb, goat, and ox are usually considered second-class veal replacements. These cuts are generally less tender than veal and have a strong flavor that may overwhelm the outcome of your dish. Is Lamb […]

What are the 3 types of regions in geography? Geographers have identified three types of regions: formal, functional, and vernacular. What is place in the 5 themes of geography? Place describes the human and physical characteristics of a location. Physical characteristics: Includes a description of such things as mountains, rivers, beaches, topography, climate, and animal […]

Is Melting snow a physical change? Melting snow is a phase change, and therefore is a physical reaction and not a chemical one. Why is melting ice cream a physical change? Ice cream melting is a physical and reversible change because it is a solid and the sun’s heat is making it melt into a […]

What is the movement of magma called? lava flow. When magma flows or erupts onto Earth’s surface, it is called lava. Like solid rock, magma is a mixture of minerals. What three factors affect the formation of magma? What three factors affect the formation of magma? Pressure, water, and temperature. What are the formation of […]

Why does tightening a string increase pitch? Tightening the string gives it a higher frequency while loosening it lowers the frequency. This higher frequency of vibration means that the air particles around the string carry a higher frequency sound wave to your ear, which perceives the higher frequency as a higher pitch. What happens if […]
