An airplane that moves 50 meters in one second has a speed why?

50m/s = 3000 m/min = 180000m/hr

Explanation: If you multiply 50m/s by 60 for a minute, you get 3000 m/min, then if you multiply that by 60 for an hour, you get 180000m/hr. Or 111.85 mph.

Hope this helps!

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
