What are the two major types of seismic waves? There are two broad classes of seismic waves: body waves and surface waves. Body waves travel within the body of Earth. They include P, or primary, waves and S, or secondary, waves. What are the slowest seismic waves? The slowest waves, surface waves, arrive last. They […]

What happens if mass and velocity are doubled?
What happens if mass and velocity are doubled? Mass and velocity are both directly proportional to the momentum. If you increase either mass or velocity, the momentum of the object increases proportionally. If you double the mass or velocity you double the momentum. What happens to the kinetic energy when the mass and velocity is […]
Why does the queen hold her wrist?
Why does the queen hold her wrist? You may have noticed that the Queen often clasps her hands together at events but it’s not to avoid awkward handshakes. Instead, the pose is intended to show that she is not threatening. “The Queen’s signature pose is the handclasp. This is a demure defence posture and it […]
What exactly is science according to philosophers?
What exactly is science according to philosophers? Category. The philosophy of science is concerned with all the assumptions, foundations, methods, implications of science, and with the use and merit of science. This discipline sometimes overlaps metaphysics, ontology and epistemology, viz., when it explores whether scientific results comprise a study of truth. How is Aristotle relevant […]
What reduces cholesterol quickly?
What reduces cholesterol quickly? A few changes in your diet can reduce cholesterol and improve your heart health: Reduce saturated fats. Saturated fats, found primarily in red meat and full-fat dairy products, raise your total cholesterol. Eliminate trans fats. Eat foods rich in omega-3 fatty acids. Increase soluble fiber. Add whey protein. Can you live […]
How high can a helium balloon go?
How high can a helium balloon go? 9,000 meters What happens to a helium balloon in space? One is that atmospheric pressure is dramatically reduced at high altitudes, so a helium balloon expands as it rises and eventually explodes. But the elasticity of rubber decreases at very low temperatures so it is possible that helium […]
Can a load be a resistor?
Can a load be a resistor? Devices called resistors are built to provide precise amounts of resistance in electric circuits. Any device that performs some useful task with electric power is generally known as a load. Sometimes resistor symbols are used in schematic diagrams to designate a non-specific load, rather than an actual resistor. What […]
Is a double bond one electron group?
Is a double bond one electron group? Double or triple bonds count as a single electron group. The molecule will not be a perfect equilateral triangle because the C–O double bond is different from the two C–H bonds, but both planar and triangular describe the appropriate approximate shape of this molecule. What are the three […]
What does the G in reaction I represent?
What does the G in reaction I represent? The (aq) sign stands for aqueous in water and means the compound is dissolved in water. Finally, the (g) sign means that the compound is a gas. Coefficients are used in all chemical equations to show the relative amounts of each substance present. What does the subscript […]
