A HUNTER FIRES A GUN AT A POINT 408 M AWAY FROM A CLIFF AND IF HE HEARS AN ECHO 2.4 S LATER, DETERMINE THE SPEED OF THE SOUND WAVE
To determine the speed of the sound wave, we can use the equation: Distance = Speed × Time Given that the hunter hears an echo 2.4 seconds later, we can assume that the sound traveled to the cliff and back.…
MAGNETIC ELEMENTS THAT DETERMINE THE EARTH’S MAGNETIC FIELD AT A POINT
The magnetic elements that determine the Earth’s magnetic field at a point are: 1) Magnetic Dipole Moment: The Earth can be approximated as a magnetic dipole, with a magnetic north pole near the geographic south pole and a magnetic south…
