Why should mass not be represented by an arrow? But, we should also remember that mass is a scalar quantity which says that mass does not have any directions. It is just the amount of matter contained in any objects. So, there is no need to represent mass by an arrow. It is a simple […]
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 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 […]
What will happen when a ringing tuning fork is lowered into water?
What will happen when a ringing tuning fork is lowered into water? When struck, the double-pronged metal rod vibrates at a constant frequency — and thus emits a constant pitch. The naked eye can’t spot the vibrations, but dipping the tuning fork in water and slowing down the footage make them anything but invisible. What […]
What is the difference between earthquake and fault?
What is the difference between earthquake and fault? Earthquakes occur on faults – strike-slip earthquakes occur on strike-slip faults, normal earthquakes occur on normal faults, and thrust earthquakes occur on thrust or reverse faults. When an earthquake occurs on one of these faults, the rock on one side of the fault slips with respect to […]
What is a periscope Class 6?
What is a periscope Class 6? A periscope is an instrument for observation over, around or through an object, obstacle or condition that prevents direct line-of-sight observation from an observer’s current position. In its simplest form, it consists of an outer case with mirrors at each end set parallel to each other at a 45° […]

What can be used to recover serial number?
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 […]
Does the Earth accelerate towards you?
Does the Earth accelerate towards you? Earth accelerates towards you So the mass of the Earth relative to you is incredibly large. From Newton’s second law of motion we know that for a given force on an object the acceleration reduces as the mass of the object increases. However the Earth still accelerates towards you […]
