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 is the most reliable way to identify a mineral?
What is the most reliable way to identify a mineral? The most reliable way to identify a mineral using color is the streak test. It is more reliable because even though the color of a specimen can vary its streak is usually the same. Which properties are used to identify minerals select 3 choices? Magnetism, […]
Can Methanol hydrogen bond with itself?
Can Methanol hydrogen bond with itself? Methanol is certainly similar to formaldehyde in some ways. It is these strong hydrogen bonds that are responsible for the relatively high boiling point of methanol; there is so much positive charge on the hydrogen of the OH group that it can essentially form a real bond with the […]
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 […]
Which mineral test is shown in the image 2 points image showing minerals that have been rubbed against a white board leaving different colored lines on the board?
Which mineral test is shown in the image 2 points image showing minerals that have been rubbed against a white board leaving different colored lines on the board? Streak test is a method to determine what color would the mineral had if it’s being transformed into a powdered form. This test is being done by […]
Why does rain make me feel safe?
Why does rain make me feel safe? Studies have found that when rain sounds enters people’s brain, brain unconsciously relaxes and produces alpha waves, which are very close to the state of brain when human sleeps. Rain sound is generally between 0 and 20 kHz. It is not upsetting. On the contrary, this sound makes […]
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 happens to the size of pupil of our eye in I Dim Light II bright light?
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 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 […]
