What is the difference between a screw and a wedge? A wedge is much bigger than any normal screw. Wedge has a plain surface but screw has a surface with ridges and grooves. • Wedge is typically used for cutting and slicing purposes but screw is typically used for fixing and attaching purposes. Is screw […]
What are the 2 main properties of sound?
What are the 2 main properties of sound? The two main properties of sound are frequency and amplitude. The frequency of the sound waves determines the pitch of the sound. The amplitude of sound determines the loudness. The quality of sound is affected by the pitch and the loudness. What is sound and its properties? […]
What is gamma decay stopped by?
What is gamma decay stopped by? Gamma radiation is the most penetrating. It can penetrate air, paper or thin metal. It may only be stopped by many centimetres of lead or many metres of concrete. What is the strongest ionizing radiation? Alpha particles What is the most dangerous type of ionizing radiation? Gamma rays are […]

To measure the distance of a star, astronomers use a baseline of 1 astronomical unit (AU), which is the average distance […]
Which mineral properties can you identify without special tools?
Which mineral properties can you identify without special tools? In working with hand samples without specialized tools, mineral hardness is specified by the Mohs hardness scale. The Mohs hardness scale is based 10 reference minerals, from talc the softest (Mohs hardness of 1), to diamond the hardest (Mohs hardness of 10). It is a relative, […]
What does refractive index indicate?
What does refractive index indicate? Refractive index, also called index of refraction, measure of the bending of a ray of light when passing from one medium into another. Refractive index is also equal to the velocity of light c of a given wavelength in empty space divided by its velocity v in a substance, or […]
How do you get marshmallows to sink?
How do you get marshmallows to sink? When you squish the marshmallow, you squeeze out the air, making it denser than the water. Now the flat marshmallow will sink. The more you squish the marshmallow, the lower it will sink. If you are having trouble with a large marshmallow, try a mini marshmallow. What liquid […]
Which atom will never form a double bond?
Which atom will never form a double bond? The double bond rule states that chemical elements with a principal quantum number greater than 2 for their valence electrons (period 3 elements and lower) tend not to form multiple bonds (e.g. double bonds and triple bonds) with themselves or with other elements. Can carbon form a […]
Why is crystallization done class 11?
Why is crystallization done class 11? Crystallisation of the filtrate This is done to ensure uniform evaporation and to prevent formation of a solid crust. When the volume of the solution is reduced to one half, dip one end of a glass rod in the concentrated solution and cool the drop by blowing on it. […]
