What forces act on a person jumping? Part II: The Jump Whether you are standing or jumping, the only external forces acting on your body are the normal force from the ground and gravity. How can you jump? Raising your center of mass into the air seems like it would require gravity to diminish or […]
What is the shape of gef2?
What is the shape of gef2? trigonal planar What is Vsepr formula? The “AXE method” of electron counting is commonly used when applying the VSEPR theory. The electron pairs around a central atom are represented by a formula AXnEm, where A represents the central atom and always has an implied subscript one. Each E represents […]
Is it safe to eat iceberg ice?
Do anions have higher first ionization energy?
Do anions have higher first ionization energy? When electrons are added to an atom there are more electron-electron replusions causing electrons to spread out more in space. Thus, anions are larger than their parent atoms. The first ionization energy of an atom is the energy required to remove the first valence electron from a neutral […]
How long does it take to stop your car at 55 mph?
How do you manipulate an independent variable?
How do you manipulate an independent variable? Again, to manipulate an independent variable means to change its level systematically so that different groups of participants are exposed to different levels of that variable, or the same group of participants is exposed to different levels at different times. How can you minimize the effects of extraneous […]
Why is my house so full of static electricity?
Why is my house so full of static electricity? Static increases when the air gets cold and humidity drops. To stay warm in your home, you turn up the heat, further adding to a decrease in humidity and increasing static. While static can be annoying and sometimes painful, there are some simple things you can […]
What is the difference between membrane potential and resting potential?
What is the difference between membrane potential and resting potential? For a cell’s membrane potential, the reference point is the outside of the cell. Because there is a potential difference across the cell membrane, the membrane is said to be polarized. If the membrane potential becomes more positive than it is at the resting potential, […]
What are the 5 main functions of the nervous system?
What are the 5 main functions of the nervous system? Central Nervous System – what does the brain and spinal cord do? maintaining homeostasis. interpreting sensory information. creating motor responses (movement) learning. thinking. talking. What are the main functions of the peripheral nervous system? The PNS has three basic functions: (1) conveying motor commands to […]
Can you have a coefficient of restitution greater than 1?
Can you have a coefficient of restitution greater than 1? It normally ranges from 0 to 1 where 1 would be a perfectly elastic collision. It can be more than 1 if there is an energy gain during the collision from a chemical reaction, a reduction in rotational energy, or another internal energy decrease that […]
