Which force is responsible for holding a car in an unbanked curve? friction What causes a car to follow a circular path? No force causes the car to do this because the car is traveling at constant speed and therefore has no acceleration. A car goes around a circular curve on a horizontal road at […]
Which substance is present in air?
Which substance is present in air? Standard Dry Air is made up of nitrogen, oxygen, argon, carbon dioxide, neon, helium, krypton, hydrogen, and xenon. It does not include water vapor because the amount of vapor changes based on humidity and temperature. Because air masses are constantly moving, Standard Dry Air is not accurate everywhere at […]
Which are the oldest mountains in the world?
Which are the oldest mountains in the world? Officially the oldest mountain range in the world, the Makhonjwa Mountains are commonly called the “Genesis of Life.” The geography of the mountains varies from rocky hills, to lush grasslands, and deeply wooded valleys. What are the most popular ranges in the world? Great Mountain Ranges Name […]
How do you find the Cartesian vector equation?
What are the 5 properties of covalent compounds?
What are the 5 properties of covalent compounds? Properties of Covalent Molecular Compounds. Low melting points and boiling points. Low enthalpies of fusion and vaporization These properties are usually one or two orders of magnitude smaller than they are for ionic compounds. Soft or brittle solid forms. Poor electrical and thermal conductivity. What is covalent […]
What does silver look like in nature?
What does silver look like in nature? For ores where the most valuable element is silver, the silver is normally contained in minerals colored gray to black in appearance. These minerals range from a metallic sheen to an earthy soot-like appearance. Most of these sooty black deposits consist of acanthite or various complex silver sulfides. […]
How does a charged particle move in a magnetic field?
How does a charged particle move in a magnetic field? A charged particle experiences a force when moving through a magnetic field. Since the magnetic force is perpendicular to the direction of travel, a charged particle follows a curved path in a magnetic field. The particle continues to follow this curved path until it forms […]
What part of the cell helps maintain a stable environment?
What part of the cell helps maintain a stable environment? But the cell membrane contains channel proteins that only water molecules can pass through. Osmosis allows cells to maintain water balance as their environment changes. When ions and polar substances dissolve in water, they attract and bind some water molecules. The remaining water molecules are […]
What is the relationship between pressure gradient and wind speed?
What is the relationship between pressure gradient and wind speed? The pressure gradient is the change in barometric pressure over a distance. Big changes within shorter distances equals high wind speeds, while environments that exhibit less change in pressure with distance generate lower or non-existent winds. What is a strong pressure gradient? When pressure is […]
Which plays the most important role in the movement of water through a plant?
Which plays the most important role in the movement of water through a plant? Roots also play an important role in water transport. Which plays the most important role in the movement of water through a plant–the absorption of water by the roots or the evaporation of water from the leaves? I feel that the […]
