Una motocicleta alcanza una velocidad de 130 km/h, en 20m ¿Cuál el tiempo empleado?

Atelevision set that has been running for a while heats up even the air around it. which two laws of thermodynamics could be used to analyze this scenario

Aboat radioed a distress call to a coast guard station. at the time of the call, a vector a from the station to the boat had a magnitude of 45.0 km and was directed 15.0° east of north. a vector from the station to the point where the boat was later found is = 30.0 km, 15.0° north of east. what are the components of the vector from the point where the distress call was made to point where the boat was found? in other words, what are the components of vector c = b - a?

The velocity of sound wave in air at 35°c is 353m/s, calculate the velocity of sound at 46°c
