What allows to float?
What allows to float? Objects with tightly packed molecules are more dense than those where the molecules are spread out. Density plays a part in why some things float and some sink. Objects that are more dense than water sink and those less dense float. When an object floats, it pushes water out of the […]
What are the common group of minerals?
What are the common group of minerals? Silicates, oxides, sulfates, sulfides, carbonates, native elements, and halides are all major mineral groups. Silicates. Oxides. Sulfates. Sulfides. Carbonates. Native Elements. Halides. What are the two main groups of minerals? All minerals, however, can be classified into two main groups—silicate minerals and nonsilicate minerals—based on the chemical compositions […]
What will the era be called when William is King?
What will the era be called when William is King? William certainly has the option of choosing a new regnal name when he becomes King (perhaps one of his middle names: Arthur, Philip, or Louis, or George, like his great-grandfather), but if he keeps William, he would be known as King William V.

How do you find a circular displacement?
How do you find a circular displacement? Angular displacement of a point can be given by using the following formula, Angular displacement = \theta _{f}- \theta _{i} Where, dv = a dt. Integrating on both sides, v – u = at. Also, v^{2} – u^{2} =2as. Substituting the value of u from the equation 1 […]
Does direction matter measuring momentum?
Does direction matter measuring momentum? Direction does not matter when you are measuring momentum. Momentum can be transferred from one object to another. When objects collide, some momentum is lost. What is the difference between momentum and velocity? As nouns the difference between velocity and momentum is that velocity is (physics) a vector quantity that […]
Is sound a standing wave?
Is sound a standing wave? Standing sound waves open and closed tubes. Sound waves are longitudinal waves in a medium such as air. The loudness or volume of the sound also increases with wave amplitude. In open and closed tubes, sounds waves can exist as standing waves as long as there is at least one […]
How far should the driver sit from the airbag?
How far should the driver sit from the airbag? roughly 10 inches Is it dangerous to not have a steering wheel airbag? A vehicle is only as safe as the driver behind the wheel. Vehicles came without airbags for decades before they became standard equipment. A safe, defensive driver can drive millions of miles and […]
What causes a changing magnetic field?
What causes a changing magnetic field? The changing magnetic field caused by the material’s motion induces a current in the coil of wire proportional to the change in field. For a 1, the magnetic field changes from one direction to the other; this change induces a current in the coil. What happens when electric and […]
