Write a short paragraph about electrical current using the terms conductor and insulator.
Answer:
An electric current is a stream of charged particles, such as electrons or ions, moving through an electrical conductor or space. It is measured as the net rate of flow of electric charge through a surface or into a control volume. The moving particles are called charge carriers, which may be one of several types of particles, depending on the conductor. An electrical insulator is a material in which the electron does not flow freely or the atom of the insulator have tightly bound electrons whose internal electric charges do not flow freely; very little electric current will flow through it under the influence of an electric field.

Identify the forces acting on you when you are standing still. Explain why the forces do not cause you to move.
Answer:
When you are standing still, you are exerting gravitational force on the ground. The downward gravitational force is balanced by the normal reaction force acting upwards. Also, since you are not moving the resultant of all forces is zero. Since the resultant force is zero, then according to Newton's 1st law, there is no change in the state of rest.

Explanation:
When an El Niño occurs, there is less wind in an area. This results in less upwelling, which in turn does not bring nutrient-rich, cold water to the surface. This has a negative impact on people who make their living from fishing. Lesson 2.12 Question 1 options: True False
When an El Niño occurs, there is less wind in an area. This results in less upwelling, which in turn does not bring nutrient-rich, cold water to the surface. This has a negative impact on people who make their living from fishing. This statement is true.
What happens when El Niño occurs?El Nio occurs when surface water in the equatorial Pacific warms above average and east winds blow weaker than usual. La Nia is the opposite condition. The water is cooler than usual during this phase of ENSO, and the east winds are stronger. El Nios occur every 3 to 5 years on average.
Trade winds weaken during El Nio. Warm water is pushed back east, toward the Americas' west coast.
During El Nio, the upwelling of cooler oceanic water along the South American coast decreases. The trade winds typically move from South America to Asia/Australia, dragging warm surface water away from the coast while colder, nutrient-rich water rises to shallow depths.
Thus, This has a negative impact on people who make their living from fishing. This statement is true.
