Temperature is just a measure of how HOT or COLD a substance is, which can be easily defined by a magnitude using a numerical value say “300 K” or “27°C”. Hence we can say it is a scalar quantity.
But the energy which transfer by virtue of a temperature difference is a vector quantity, as it has both magnitude and direction of motion (from High temperature to low temperature region).
B I believe is the answer!
Hope this helps and have a great day!!!
Rate of speed (3 m/s north is three miles per second north, so it's a rate of speed)
B low frequency it is the lowest frequency
Answer:
Energy May be measured in joule
