Why do we use thin gold foil?
Why do we use thin gold foil? For the scattering experiment, Rutherford wanted a metal sheet which could be as thin as possible. Gold is the most malleable of all known metals. It can easily be converted into very thin sheets. Hence, Rutherford selected a gold foil for his alpha-ray scattering experiment. What was most […]
Is it possible to increase the temperature of a gas without giving it heat?
Is it possible to increase the temperature of a gas without giving it heat? Yes, during adiabatic compression the temperature of a gas increases while no heat is given to it. In compression work is done on the gas i.e. , work done is negative. Hence, internal energy of the gas increases due to which […]
How is flux generated?
How is flux generated? When a coil of wire is moved through a magnetic field a voltage is generated which depends on the magnetic flux through the area of the coil. Electric motors and generators apply Faraday’s law to coils which rotate in a magnetic field as depicted in Figure 3. In this example the […]
What is an example of a confirmation bias?
What is an example of a confirmation bias? Confirmation biases impact how we gather information, but they also influence how we interpret and recall information. For example, people who support or oppose a particular issue will not only seek information to support it, they will also interpret news stories in a way that upholds their […]
What forms when water does not soak immediately underground?
What forms when water does not soak immediately underground? Water that soaks into the soil can also continue to percolate down through the soil profile below the water table into groundwater reservoirs, called aquifers. Water that doesn’t soak into the soil collects and moves across the surface as runoff, eventually flowing into streams and rivers […]
What colors make a room feel cooler?
What colors make a room feel cooler? Light colors will reflect heat while darker shades absorb it. This means that it will be easier to cool a room with white walls rather than one with black walls. Lighter shades will make your space feel cooler and easier to cool,” says interior designer Vera Villarosa-Orila. What […]
Are switch loops legal?
How is the law of definite proportions important?
How is the law of definite proportions important? The law of definite proportions dictates that a name is always associated with a specific ratio of elements found in a chemical compound. If the ratio of elements is different from that specific ratio then it is not the same compound and therefor has a different name. […]
What are the rules for current in series and parallel circuits?
What are the rules for current in series and parallel circuits? Chapter 5 – Series And Parallel Circuits Voltage: Voltage is equal across all components in a parallel circuit. Current: The total circuit current is equal to the sum of the individual branch currents. Resistance: Individual resistances diminish to equal a smaller total resistance rather […]
