9. Which of the following is true regarding current in an external circuit? A. A direct current constantly switches direction of flow to match the change of charge at each terminal.
B. Direct current always moves from the positively charged terminal to the negatively charged terminal.
C. Alternating current always moves from the positively charged terminal to the negatively charged terminal.
D. The flow of an alternating current switches direction when a generator's terminals change its charge.

The answer is:

The track of the storm determines how much rain will fall.

The explanation:

-Storm tracks are the relatively narrow zones in seas and oceans where storms travel driven by the prevailing winds.

-hurricane is a tropical cyclone with winds of 74 miles (119 kilometers) per hour or greater that occurs especially in the western Atlantic, that is usually accompanied by rain, thunder, and lightning, and that sometimes moves into temperate latitudes. and it has aspects that can cause damage, these are flood, wind, surge, heavy rains and tornadoes.

The work is an effect that is observed due to the application of force. Taking the concern of work-energy principle, the work is done when there is a transfer of energy take place.

What is Work Done?

When some magnitude of the force is being applied on an object to displace, then the term used to describe the effect is known as work done.

The mathematical expression for the work done is given as,

W = F × d

here,

F is the magnitude of applied force.

d is the displacement.

If we compare work with energy then, Energy, on the other hand, is the ability to do work. According to the work-energy principle, a change in the kinetic energy is equivalent to the net work done by the object. Therefore, energy is being transferred from one point to another when work is being done.

Thus, we can conclude that the work is done when a transfer of energy takes place.

Answer;

Energy is being transferred

Explanation;

• Work is the force applied over a given distance, in other words work is the product of force and distance.

Work = force × distance.

• Work is measured in Joules.

• Energy on the other hand, is the ability to do work.
• According to the principle of work-energy a change in the kinetic energy is equivalent to the net work don e by the object. Therefore, when work is being done energy is being transferred from one point to another.

the answer to this question is B relative humidity!

The correct answer to the question is : Photosphere i.e it is the region whose temperature is 6000 degree celsius.

EXPLANATION:

The Sun has many regions starting from photosphere to central core. Different regions of the sun has different temperature.

The temperature of the sun is due to the fusion occurring inside it. The core temperature is immense due to the gravitational attraction which produces more heat there. Gradually the temperature decreases as we move away from the sun core.

As per the question, the temperature is given as 6000 degree celsius.

The region of the sun which corresponds to this temperature is photosphere. The temperature of photosphere varies from 5500 degree celsius to 7500 degree celsius. The temperature of sunspots found in the sun may be lower than the average temperature of the photosphere.

Hence, the correct answer is Photosphere.
