Question

what is the difference between (i) hertz and decible (ii)axis and orbit

Answer 1

HERTZ AND DECIBEL
The frequency of a sound is the number of cycles of a sound wave in one second. The unit of measurement is hertz (Hz) whereas, The term dB(deciBel) and the dB scale are used world-wide for the measurement of sound levels. The value of a dBdepends on the context in which it is used.
AXIS AND ORBIT
Axial tilt, otherwise known as the obliquity of the ecliptic, is thedifference in the angle between the Earth's orbital axis and its rotational one. Or in simpler terms, it's the fact that the Earth is tilted - the Earth rotates around an axis that isn't at 90 degrees to the direction it orbitsaround the Sun.
