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.…
A LAMP IS RATED 240 V, 60 W AND DETERMINE THE RESISTANCE OF THE LAMP WHEN LIT
To determine the resistance of a lamp when it is lit, we can use Ohm’s Law. Ohm’s Law states that the current flowing through a conductor is directly proportional to the voltage applied across it and inversely proportional to its…
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…
METHODS TO DETERMINE HOST BACTERIAL CELLS CONTAINING CLONAL INSERT
1. Selection Markers One method to determine which host bacterial cells contain the clonal insert is by using selection markers. These markers are genes that confer a selective advantage to the host cell when they are present. For example, if…
