What happens next depends on the mass of the star? About 75% of the mass of the star is ejected into space in the supernova. The fate of the left-over core depends on its mass. If the left-over core is about 1.4 to 5 times the mass of our Sun, it will collapse into a […]
Why is Pluto white?
Why is Pluto white? Pluto is the only place other than Earth in our solar system that’s known to have white-peaked mountains, but these white caps aren’t made of snow. Instead, they’re made of methane frost. The mountains are made of water ice, as temperatures on this dwarf planet can drop as low as minus […]
What landform is created when two continental plates collide?
What landform is created when two continental plates collide? mountains What are the three types of oceanic continental convergence? The three possibilities are oceanic crust to oceanic crust, oceanic crust to continental crust, or continental crust to continental crust. If at least one of the slabs of lithosphere is oceanic, that oceanic plate will plunge […]
Why does the viscosity of liquids decrease with temperature?
Why does the viscosity of liquids decrease with temperature? The increase in temperature causes the kinetic or thermal energy to increase and the molecules become more mobile. The attractive binding energy is reduced and therefore the viscosity is reduced. How does viscosity of liquids vary with temperature? The viscosity of liquids decreases rapidly with an […]
Why are electric fields uniforms?
Why are electric fields uniforms? The force on the charge is the same no matter where the charge is located between the plates. This is because the electric field is uniform between the plates. What happens if the field is non uniform? ➡️Torque is non zero when dipole is placed in uniform as well as […]
What is the most geologically active moon?
What is the most geologically active moon? Io Are geologically active areas? These boundaries, the danger lines described in the SAVAGE EARTH program “Hell’s Crust,” are the most geologically active regions on Earth. Through decades of observation and experiment, scientists have developed a picture of Earth’s interior and the forces that produce the violent activity […]
How do you calculate the maximum load on an electrical panel?
How do you calculate the maximum load on an electrical panel? Calculating Load Add together the wattage capacity of all general lighting branch circuits. Add in the wattage rating of all plug-in outlet circuits. Add in the wattage rating of all permanent appliances (ranges, dryers, water heaters, etc.) Subtract 10,000. Multiply this number by . […]
What kills the pasteurization process?
What kills the pasteurization process? This process was named “pasteurization” after its brilliant designer. Pasteurization involves heating liquids at high temperatures for short amounts of time. Pasteurization kills harmful microbes in milk without affecting the taste or nutritional value (sterilization= all bacteria are destroyed). Which bacteria is not killed by pasteurization? The pasteurization technology, applied […]
What kind of heat transfer happens when the sun is hitting your body?
How long did 17th century plague last?
How long did 17th century plague last? Between 1563 and 1665, London experienced four plagues that each killed one fifth of the city’s inhabitants. This column uses 790,000 burial records to track the plagues that recurred across London (epidemics typically endured for six months). How long did Spanish flu last? The influenza pandemic of 1918–19, […]
