A string of lights in a series circuit is not working. Which of the following is most likely the cause?
Brums [2.3K]

Answer:

A. A light burned out and "opened" the circuit

Explanation:

In a parallel circuit if a light bulb goes out the rest are fine because they each have independent routes to the battery. But in a series circuit when a light bulb goes out the rest goes out because the current is going in one pathway. To tell the difference of if it closed or opened the circuit, you have to know what they mean. Closing a circuit means a complete electrical connection, the  light bulbs will light and electricity will flow. Opening a circuit means the opposite. If the all the light bulbs have stopped working then the circuit is not complete, therefore it's open.

During volume changes in the thoracic cavity, what is primarily responsible for changes in length?.
rusak2 [61]

During volume changes in the thoracic cavity, <u>Diaphragm</u> is primarily responsible for changes in length.

The main components of the respiratory system are the two lungs. They are located in the thoracic cavity, which is the area to the left and right of the heart. The rib cage safeguards the cavity. Other components of the respiratory system are supported by a muscular sheet known as the diaphragm.

The diaphragm contracts and pulls downward upon inspiration, or when the lungs inhale. The muscles between the ribcage tighten and pull upward at the same time. As a result, the pressure inside the thoracic cavity lowers and its size grows. Air rushes in as a result, filling the lungs.

Thus, diaphragm is responsible for the increase in length of the thoracic cavity.
