How do you figure out when two trains will meet? If the length of two trains is given, say a and b, and the trains are moving in opposite directions with speeds of x and y respectively, then the time taken...
How fast is a normal train? Federal regulators limit the speed of trains with respect to the signaling method used. Passenger trains are limited to 59 mph and freight trains to 49 mph on track without block signal systems. (See dark...
When faster we travel in space the slower we travel in time? That depends on how fast you’re traveling. Thanks to Einstein, we know that the faster you go, the slower time passes–so a very fast spaceship is a time machine...
What is a fast flow of water in a river called? Areas of shallow, fast-flowing water in a stream are known as rapids. Rapids are the main source of thrilling activities like rafting. What causes rapids? Rapids are sections of a...
When glaciers melt they drop the rocks they were carrying what is it called? Melting glaciers deposit all the big and small bits of solid material they are carrying in a pile. These unsorted deposits of rock are called glacial till....
What is the fastest venomous snake? What is fastest snake in the world? Rank Species Strike Speed 1 Sidewinder 18 mph 2 Cottonmouth 2.97 meters per second 3 Rat Snake 2.67 meters per second 4 King Cobra Time to Kill a...
Why do objects get heavier the faster they go? Einstein used relativity to show that as you approach the speed of light times beats slower, space contracts and you get heavier. The faster you move, the heavier you get. Energy of...
Do faster waves have shorter wavelengths? Since speed increases and frequency is unchanged, the wavelength must increase. (Increasing the number for wave speed in the equation λ=v/f λ = v / f without changing the number for frequency will lead to...
What is also called a mudflow? Lahars, also known as volcanic mudflows, are hot or cold mixtures of water, rock, sand, and mud moving down the flanks of a volcano and running away from it. Lahars look like fast-moving masses of...
What is a volcanic mudflow called? Volcanic mudflows (lahars and debris flows) occur more commonly after a landscape has been covered by loose volcanic material. What is volcanic debris called? BGS Research — Volcanoes. Debris flows, also known as lahars when...
