How hard is 30 HRC? 30 HRC is the hardness of the steel. It’s not a type of steel. That being said, 30 HRC is atrociously soft. Its edge would dull very quickly if you used it to cut anything. Which is harder HRB or HRC? The Rockwell C scale is usually abbreviated HRC (Hardness […]
What forces act on a ball?
What forces act on a ball? The forces are the weight, drag, and lift. Lift and drag are actually two components of a single aerodynamic force acting on the ball. What kind of force is wind? In summary, the wind is controlled by the pressure gradient force (differences in barometric pressure), the Coriolis Force and […]
Did Pompeii victims die instantly?
Did Pompeii victims die instantly? The individuals in the boat houses died relatively quickly: The volcanic ash blocked the entrance to each structure, and the temperature of the air within probably rose to about 400°C—even hotter than a wood-fired oven. … Was Pompeii covered in ash or lava? The city of Pompeii is famous because […]
How is angular frequency related to time?
How is angular frequency related to time? It is the reciprocal of the period and can be calculated with the equation f=1/T. Some motion is best characterized by the angular frequency (ω). The angular frequency refers to the angular displacement per unit time and is calculated from the frequency with the equation ω=2πf. What does […]
What is the importance of market equilibrium?
What is the importance of market equilibrium? Equilibrium occurs when the price is such that the quantity that consumers wish to buy is exactly balanced by the quantity that firms wish to supply, again there is no tendency for price to change. So, it is price that brings a market into equilibrium. What are examples […]
What are the advantages of Tides Class 7?
What are the advantages of Tides Class 7? Advantages of High Tide: They help in navigation. They raise the water level close to the shores and help the ships to arrive at the harbor more easily. They help in fishing. More fish come closer to the shore during high tides. What is the importance of […]
Which of the following is an example of scientific law?
Which of the following is an example of scientific law? An example of a scientific law is the law of conservation of mass, which states that matter is neither created nor destroyed in a chemical reaction. What are some examples of scientific laws? Other examples of laws in physical science include: Newton’s first law of […]
What happens to capacitance if distance is increased?
What happens to capacitance if distance is increased? Capacitance is directly proportional to the electrostatic force field between the plates. This field is stronger when the plates are closer together. Therefore, as the distance between the plates decreases, capacitance increases. Therefore, as the dielectric constant increases, capacitance increases. Is capacitance proportional to distance? Capacitance (C) […]
Are cumulus clouds dangerous?
Are cumulus clouds dangerous? Thus, cumulonimbus are known to be extremely dangerous to air traffic, and it is recommended to avoid them as much as possible. Cumulonimbus can be extremely insidious, and an inattentive pilot can end up in a very dangerous situation while flying in apparently very calm air. Do pilots try to avoid […]
