Stand on two feet, walk in a straight line and be careful to not trip/step on anything that could make me lose my balance
Answer:
Source of current, force and pathway.
Explanation:
Source of current, force and pathway are the three important things needed or responsible for the current flow. A supply of electric charges (electrons) which is provided by the electric source, force of push to move the charges through the circuit and a pathway on which current flows. Without these three things, flow of current is impossible. so we can say that the situation in which all these three things are present will allow the current to flow in the circuit.
Answer:
The environment that it lives in has not changed much, therefor there is no need for evolution to take place.

QUESTION:-
What is the maximum number of electrons that can be placed in the first shell/energy level?
A. 1
B. 8
C. 2
D. 18
Answer:
C. 2
The first shell, closest to the nucleus and with the lowest-energy electrons, is shell 1. This first shell has only one subshell (labeled 1s) and can hold a maximum of 2 electrons
The correct flowchart is energy - > atmosphere - > air pressure - > convection - > global winds. This is a very simple process as explained.
<h3><u>Explanation:</u></h3>
The energy from the sun actually heats up the land surface and the water surface of the earth. As the land gets heated up, the layer of atmosphere that is adjacent to the land and water also gets heated up. This leads to the decrease of air density as the heat causes expansion of gases. With decrease in air density, the air pressure also drops and the air from the cooler layer of atmosphere above comes to fill up the space and this heated air goes up. This causes the convection current to get set up. This causes the global winds and different oceanic currents to flow all over the earth throughout the year.
