Steel, but it has to do not just with the density of the material, but also another material property. The real reason that sound will travel faster in steel is that it is more rigid (stiff). The more rigid the substance, the stronger the restoring force and thus the quicker a disturbance will travel through it.

d) steel.

b/c don't you see the indian or cowboy placing their ear on the railroad tracks to listen if the train is coming.

Another question would be how much energy you would need to transmit sound through steel. Like your voice travelling through steel would be very difficult unless you made a tin cup with a wire connecting either ends, but then what about electrical currents on metal like telegraphy or the phone.

Answer should be steel coz the intermolecular spacing between the atoms is least in steel amongst the 4 options n hence it'll be easier for sound to travel in steel and hence fastest

a) 1310 m/s at 27 °C

b) In saltwater about 1500 m/s and in freshwater 1435 m/s near the surface, faster as you go deeper.

c) 331.5 m/s at 0 °C / 32 °F, faster if the temperature is higher
= 1087.6 ft/s = 1193 km/h = 741.5 mph = 643.9 knots

d) 5100 m/s

The winner is the steel...

definately steel because sound travels by vibrations, so the closer the paqrticles the faster the sound travels

Steel....the denser the substance, the faster that sound will be transmitted.

Metals carry sound waves faster than water which transfers them faster than air. Sound travels 10-15 times faster in metals than in gases; while in liquids, it travels 4-5 times faster than in dry air.

Steel, because the density is more
