What three conclusions came from the gold foil experiment? most of the alpha particles did pass straight through the foil. a small number of alpha particles were deflected by large angles (> 4°) as they passed through the foil….Rutherford and the nucleus. What happened Rutherford’s conclusions Most of the alpha particles did pass straight through […]
What are the two types of surface waves?
What are the two types of surface waves? The two types of surface waves are named Love waves and Rayleigh waves, after the scientists who identified them. Love waves have a horizontal motion that moves the surface from side to side perpendicular to the direction the wave is traveling. Of the two surface waves, Love […]
Does helium go bad?
Does helium go bad? No, helium does not expire. You must close the valve tightly or helium will leak over time. Are Balloon Time tanks recyclable? What weight can helium lift? Helium atoms weigh less than the oxygen and nitrogen atoms in the air. Helium has a lifting force of about one gram per litre. […]
What does the summer solstice mean spiritually?
What does the summer solstice mean spiritually? Here, at the Summer Solstice, the longest day of the year, we are fully awake. Our spirits are alive, refreshed, renewed, energized; all that good, juicy, rich stuff we feel in the sun. On these long days of summer our spirits yearn to be out, to feel alive, […]
Why do the two slits need to be small in order for an interference pattern to occur?
Why do the two slits need to be small in order for an interference pattern to occur? The very short wavelengths of visible light explain why interference effects are observed only in special circumstances—the spacing between the sources of the interfering light waves must be very small to separate regions of constructive and destructive interference. […]
Can I sue my employer for not reporting my injury?
Can I sue my employer for not reporting my injury? Updated January 3, 2021 An employee injured on the job in California is generally limited to seeking recovery by filing a workers’ compensation claim. This means he or she cannot sue the employer in civil court. Can you get fired for not reporting an injury? […]
What are 2 examples of mechanical waves?
What are 2 examples of mechanical waves? A sound wave is an example of a mechanical wave. Sound waves are incapable of traveling through a vacuum. Slinky waves, water waves, stadium waves, and jump rope waves are other examples of mechanical waves; each requires some medium in order to exist. Who discovered scalar waves? Heinrich […]
Is White Fang a dog or wolf?
Does drag force increase as velocity increases?
Does drag force increase as velocity increases? The downward force of gravity remains constant regardless of the velocity at which the person is moving. However, as the person’s velocity increases, the magnitude of the drag force increases until the magnitude of the drag force is equal to the gravitational force, thus producing a net force […]
What frequency makes you smarter?
What frequency makes you smarter? The highest frequency brain waves are apparently called gamma waves. These waves can have a frequency of anywhere between 25 and 100 Hz. People whose brains produce more gamma waves are said to have greater ability to concentrate, focus and experience higher levels of cognition. Will reading increase IQ? It […]
