Assuming the same volume, yes.


What is the greatest possible number of points of intersection for eight distinct lines in a plane?

Greatest possible number of intersections for following lines:1(line(s)) = 0 (intersections)2= 13= 1+24= 1+2+35= 1+2+3+4....8=1+2+3+4+5+6+7= 28Every time you add a line, you are able to create 1 more maximum intersection than the previous state. You can add up until 'number of lines - (minus) 1'.


Do roundabouts cause more accidents than traditional intersections?

Studies have shown that roundabouts generally reduce the number and severity of accidents compared to traditional intersections.


Why does helium have more emission lines than hydrogen?

Helium has more emission lines than hydrogen because it has more electrons and energy levels, leading to more possible transitions between these levels and the emission of different wavelengths of light.


Why are roundabouts considered to be more efficient than traditional intersections?

Roundabouts are considered more efficient than traditional intersections because they help reduce traffic congestion, minimize the likelihood of collisions, and improve traffic flow by eliminating the need for traffic signals.


More crashes happen than any other place?

Crashes are more likely to happen at intersections due to vehicles crossing paths, turning, and traffic signals. Intersections are common locations for accidents because they involve multiple streams of traffic converging in different directions. Drivers need to be cautious and follow road signs and signals to reduce the risk of collisions at intersections.


Shapes with more than 4 lines of symmetry?

A regular hexagon has more than 4 lines of symmetry. Even number sided polygons that are regular and have more than 4 sides have more than 4 lines of symmetry. Circles have more than four lines of symmetry. Squares also have 4 lines of symmetry.


What place has more crashes intersections or expressways?

Intersections generally experience more crashes than expressways due to the higher frequency of conflict points, such as turning vehicles, pedestrians, and cyclists. The complexity of traffic movements and the presence of stop signs or traffic signals contribute to a higher incidence of accidents at intersections. However, expressways can have more severe crashes due to higher speeds and fewer escape routes. Overall, while intersections have more total crashes, expressways can be more dangerous when accidents occur.


Why does xenon display more spectral lines than helium?

Xenon has more spectral lines than helium due to its more complex electron configuration with multiple electron orbitals and subshells. This leads to a greater number of possible energy transitions for its electrons, resulting in a larger variety of spectral lines when these transitions occur. In contrast, helium has a simpler electron configuration with only two electrons, leading to fewer possible energy transitions and thus fewer spectral lines.


How many more crashes happen at intersections with traffic control devices than without traffic control devices?

Fewer.
