What can be used to recover serial number? etching reagent Which chemical helps reveal a damaged serial number? To reveal destroyed serial numbers on weapons made of nonmagnetic materials, such as zinc, aluminum or alloy substances, crime laboratories must still use chemical etching, a process that uses strong acids and typically reveals a serial number […]
Is scattering of light reflection?
Is scattering of light reflection? Scattering and reflection. Both phenomena occur and overlap. The main factor controlling them is particle size: scattering occurs for particles smaller than the wavelength of light, and reflection for bigger ones, but there is overlap. Thus, more blue light than red light is transmitted backwards. What is the means of […]
How many types of erosion are there?
How many types of erosion are there? Like water erosion, there are three different types of wind erosion, surface creep, saltation, and suspension. What is called erosion Class 6? The wearing away of the earth’s surface is called erosion. Explanation: Erosion is the phenomenon of the removal of the top layer of the Earth’s surface […]
What has 16 protons and 18 neutrons?
What has 16 protons and 18 neutrons? Sulfur – S Is beryllium expensive? BERYLLIUM IS A MATERIAL LIKE NO OTHER. Ninety-eight-percent pure beryllium is expensive, selling from $600 to $800 per pound prior to machining, so shops must understand its machining idiosyncracies to avoid scrapping progressively expensive parts. What’s the strongest alloy on earth? Steel […]
What would happen if a gamma ray hit Earth?
What would happen if a gamma ray hit Earth? With the gamma-rays beamed directly at Earth, the radiation would destroy a significant portion of our atmosphere, specifically the ozone layer. The photons streaming from the burst would cause chemical reactions leading to photochemical smog. This would further deplete our protection from cosmic rays. How far […]
Which type of organisms are called consumers?
Which type of organisms are called consumers? Consumers are typically viewed as predatory animals such as meat-eaters. However, herbivorous animals and parasitic fungi are also consumers. Which organisms are considered Heterotrophs? Heterotrophs are known as consumers because they consume producers or other consumers. Dogs, birds, fish, and humans are all examples of heterotrophs. Heterotrophs occupy […]
How do plants and animals get the energy they need?
How do plants and animals get the energy they need? Most, if not all plants are producers, and they make their own food using sunlight and raw materials, through a process called “photosynthesis”. Plants get their energy in form of starch whereas animals get it in form of glycogen. In which light photosynthesis is maximum? […]
Which fossil fuel is the best?
Which fossil fuel is the best? Natural Gas Which fossil fuel is the cleanest burning Why? natural gas What is the most used fossil fuel? Oil How much does burning fossil fuels contribute to global warming? Global carbon emissions from fossil fuels have significantly increased since 1900. Since 1970, CO2 emissions have increased by about […]
What is the weight of a human kidney?
What force is used when you lift an object?
What force is used when you lift an object? gravitational potential energy Is it safer to push or pull a trolley? Putting the load on a trolley and pushing it is one way of avoiding carrying. So, when people push and pull instead of lifting and carrying, less effort is required, but there may still […]
