Two iron rods are placed horizontally, touching end-to-end. one end of one rod is heated. after some time, the other rod also feels warm to touch. how did the heat travel from the heated rod to the one that was not heated?
a) the air over the heated rod traveled to the other rod and made it warm.
b) part of the heat was converted to radiation and traveled to the cooler rod.
c) electrons within the rods started moving, distributing heat consistently in both rods.
d) the molecular movement in the first rod transferred energy to the molecules in the second.

the total distance traveled by the car is

30km + 49km = 79 km .

it's when something is going so fast it makes a loud noise, breaking the sound barrier, for example: a jet makes a loud noise, not only cause of the jet but because they reached a point where they went so fast that you can year the noise from various parts, kinda like a police car, lets say the car was going   so fast that you hear the siren of the cop car right next to you, but the car is probably a mile a way, it's cos the siren was next to you a few seconds if you understand me

c) power lifting, will be your answer.
