Explanation:A P-wave is one of the two main types of seismic waves. P-waves travel faster than other seismic waves and hence are the first signal from an earthquake to arrive at any affected location or at a seismograph
When there is a sudden release of energy due to earthquake or any type of explosion inside the earth, then this energy is transferred in the form of waves called Seismic Waves.
Seismograph helps us to measure these waves.
These seismic waves can be categorized as Body Waves and Surface Wave.
Body Waves propagate inside the earth in all directions, and are further classified as Primary Waves (P-Waves) and Secondary Waves (S-Waves).The Surface Waves move along the earth’s surface, like the ripples on water surface.
The current is defined as the amount of charge Q that passes through a given point of a wire in a time : Since I=500 A and the time interval is the charge is
One electron has a charge of , therefore the number of electrons that pass a point in the wire during 4 minutes is electrons
Explanation: cells get their sugar molecules from the food that is taken in by an organism. The food taken in is digested by the stomach into base materials like sugar, fatty acids and amino acids. These base materials are circulated through the blood till they get to the cells where they are needed.
:
, therefore the number of electrons that pass a point in the wire during 4 minutes is
electrons
