What are the 2 types of mass? In classical mechanics, there are three types of mass or properties called mass: Inertial mass; passive gravitational mass; and active gravitational mass. Where do we use mass in everyday life? Another example of everyday use is mass producing a recipe. Say you are making an extremely large cake […]
What is the perfect male body shape?
What is the perfect male body shape? According to several studies on what the ideal male body looks like, “The physique of a slim waist, broad shoulders and muscular chest are often found to be attractive. A near-universal sexually attractive feature of a man is a V-shaped torso: a relatively narrow waist offset with broad […]

Are whales friendly?
Are whales friendly? From a historical perspective, whales do appear to be non-aggressive. Their relatives, the dolphin’s species, tend to be very friendly and curious towards humans, often displaying a desire to greet and meet people. Is it illegal to touch a whale? It is illegal, she said, for a person to come within 300 […]
Which is the best example of law of conservation of mass?
Which is the best example of law of conservation of mass? The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction. For example, when wood burns, the mass of the soot, ashes, and gases equals the original mass of the charcoal and the oxygen when it first […]
How does NASA get rid of asteroids?
How does NASA get rid of asteroids? When the asteroid is still far from the Earth, a means of deflecting the asteroid is to directly alter its momentum by colliding a spacecraft with the asteroid. The principle of the kinetic impactor mitigation method is that the NEO or Asteroid is deflected following an impact from […]
What are the three types of valleys?
What are the three types of valleys? Erosional valley: A valley formed by erosion. Structural valley: A valley formed by geologic events such as drop faults or the rise of highlands. Dry valley: A valley not created by sustained surface water flow. Longitudinal valley: An elongated valley found between two nearly-parallel mountain chains. How do […]
Why is boron an exception?
Why is boron an exception? The problem with this structure is that boron has an incomplete octet; it only has six electrons around it. Hydrogen atoms can naturally only have only 2 electrons in their outermost shell (their version of an octet), and as such there are no spare electrons to form a double bond […]
What is a positive terminal and negative terminal?
What is a positive terminal and negative terminal? Electrical polarity is a term used throughout industries and fields that involve electricity. There are two types of poles: positive (+) and negative (−). This represents the electric potential at the ends of a circuit. A battery has a positive terminal (+ pole) and a negative terminal […]
