What are some daily physical activities? Aerobic Exercises Brisk walking. Bicycle riding. Dancing. Hiking. Rollerblading. Skateboarding. Martial arts such as karate or tae kwon do (can be vigorous too) How can you make physical activity fun? Ready, set, play! Walking/running games. Going for a walk or a jog is an easy and accessible type of […]
What is the relationship between optical density and refractive index?
What is the relationship between optical density and refractive index? The physical density of a material refers to the mass/volume ratio. Optical density determines how much a light wave is slowed down as it passes through a medium. The more optically dense a material is, the slower that a wave will move through the material. […]
How do you determine whether a molecule is polar quizlet?
How do you determine whether a molecule is polar quizlet? To determine whether a molecule is polar: Draw the Lewis structure of the molecule and determine its molecular geometry. Determine whether the molecule contains polar bonds. Determine whether the polar bonds add together to form a dipole moment. How do you determine whether a molecule […]
Why do larger particles diffuse slower?
Why do larger particles diffuse slower? Temperature: Particles move due to the kinetic energy associated with them. As temperature increases, the kinetic energy associated with each particle also increases. As a result, particles will move faster. Mass of Particle: Heavier particles will move more slowly and so will have a slower rate of diffusion. Do […]
How long will gas cars be around?
How long will gas cars be around? Even if the production of combustion engines stopped today, they would continue to be driven for at least 60+ years, and likely longer. It’s estimated that there are thousands of Ford Model T’s still considered to be roadworthy, even 90+ years after production stopped. At what point in […]
What is the electron geometry of bi3?
What is the electron geometry of bi3? trigonal planar What is the electron geometry for XeF2? There are two pairs of bonded electrons and three lone pairs of electrons. The lone pairs are on the equatorial position to the bonded pairs. The bond angle between the two pairs bonded with the central atom is 180 […]
What is the weakest element?
What is the weakest element? Diamond is the hardest known natural substance and for that reason it is often used in drill bits. For the weakest element, I would probably go for helium – one of the noble gases. It is very light and unreactive. Are all atoms neutral? Every element has the same number […]
Which satellite has the greatest gravitational force with earth?
Which satellite has the greatest gravitational force with earth? satellite D What planet has most gravity? Jupiter What has the strongest gravitational pull in the universe? The Sun What is the name for the force of gravity acting on an object? weight What happens to air resistance when an object accelerates? As an object falls, […]
Which one of the following is a control on magma viscosity?
Which one of the following is a control on magma viscosity? A magma’s viscosity is largely controlled by its temperature, composition, and gas content (see downloadable programs at the bottom of this page). The effect of temperature on viscosity is intuitive. Like most liquids, the higher the temperature, the more fluid a substance becomes, thus […]
What are the 5 stages of group development?
What are the 5 stages of group development? Psychologist Bruce Tuckman developed his group development model in 1965 to explain how healthy teams cohere over time. Tuckman’s model identifies the five stages through which groups progress: forming, storming, norming, performing, and adjourning. How long does it take for a human brain to fully develop? about […]
