What type of collision is a hockey goalie catching a puck? An ice hockey goalie catches a hockey puck and recoils backward. The initial kinetic energy of the puck is almost entirely converted to thermal energy and sound in this inelastic collision. What is the movement of a hockey puck? If there is a net […]

When a hockey player is moving northward and suddenly turns westward with the same speed to avoid an opponent? A hockey player is moving northward and suddenly turns westward with the same speed to avoid an opponent. The force that acts on the player is. Frictional force along westward. When a hockey player hits a

How does a vortex tube work? A vortex tube creates cold air and hot air by forcing compressed air through a generation chamber, which spins the air at a high rate of speed (1,000,000 rpm) into a vortex. The high-speed air heats up as it spins along the inner walls of the tube toward the

How does a Hilsch tube work? Therefore, air stream through the core gets cooled below the inlet temperature of the air in the vortex tube, while air stream in forward direction gets heated up. The cold stream is escaped through the back side cold part, while hot stream is passed through the opening of the

What happens when a high-pressure system moves into an area? In an anticyclone (high pressure) the winds tend to be light and blow in a clockwise direction (in the northern hemisphere). Also, the air is descending, which reduces the formation of cloud and leads to light winds and settled weather conditions. Where do high pressure

What is a fast moving flow consisting of a mixture of water and pyroclastic debris called? Lahars. Lahar is a Javanese word for a type of volcanic mudflow made up of volcanic debris and hot or cold water. Lahars move at speeds that range from less than 10 kph up to tens of kilometres per

What is the fastest pyroclastic flow? Even some of the fastest known pyroclastic flows observed, such as the blast at Mount St. Helens, was moving around ~600 kilometers per hour (370 mph). How do pyroclastic flows move so quickly? Pyroclastic density currents are ground-hugging flows of hot volcanic gases and particles (volcanic ash, pumice, crystals,

What type of move is helping hand? Helping Hand is a status-boosting Normal-type move. Is helping hand a priority move? Helping Hand is an increased priority move that will increase the damage done by the user’s ally this turn by 50%. It will fail if there is no adjacent ally, or if the ally has

What is the velocity of a helium atom? The mass of a helium atom is 4.0026 amu, and its average velocity at 25 °C is 1.36 * 103 m/s. Why is helium atomic mass 2? Its atomic number is 2, so it has two protons in its nucleus. Its nucleus also contains two neutrons. Since

How many neutrons does helium have if its atomic mass is 4 U? Therefore, No. of Neutrons in Helium atom = 2. What is a mass of 4u? Helium atom has an atomic mass of 4 u and two protons in its nucleus. How is the atomic mass of helium-4? Helium-4 atom is the stable
