Digestive system includes the esophagus, pancreas, and large intestine. Correct option is A.
The organs mentioned, namely the esophagus, pancreas, and large intestine, are all part of the digestive system. The digestive system is responsible for processing food, breaking it down into nutrients, absorbing those nutrients, and eliminating waste products from the body. Here's a brief description of the mentioned organs' roles in the digestive system:
Esophagus: The esophagus is a muscular tube that connects the mouth to the stomach. Its primary function is to transport food from the mouth to the stomach through a process called peristalsis, which involves rhythmic muscle contractions.
Pancreas: The pancreas is both an endocrine and exocrine gland. As part of the digestive system, it plays a crucial role in producing digestive enzymes and releasing them into the small intestine. These enzymes aid in the breakdown of carbohydrates, proteins, and fats, enabling their absorption.
Large Intestine: The large intestine, also known as the colon, is the final part of the digestive system. It is responsible for absorbing water and electrolytes from undigested food, forming feces, and eliminating waste from the body through the rectum and anus.
Together, these organs work harmoniously within the digestive system to ensure the proper digestion and absorption of nutrients, as well as the elimination of waste materials.

The speed of the pendulum is greatest at the midpoint of the pendulum marked 3.
A pendulum is an device that can be used to demonstrate oscillation. We know that in pendulum the potential energy is maximum at the ends of the pendulum.
Thus, the speed of the pendulum is greatest at the midpoint of the pendulum marked 3.

Answer:
The speed of the pendulum is at maximum at x=0
the principal energy level
B.
the shape of the orbital
C.
the energy of the orbital
D.
the ground state
The answer is A. the principal energy level
The principal energy level or principal quantum number n, tell us about the position of an determined electron in the energy levels relative to the greater average distance of an electron from the nucleus, the larger the value of n and the higher its energy.
The principal energy levels contains n sublevels, orbitals and electrons.
For example, the number 1, has one orbital which is contained in a energy sublevel, its called s orbital, and it's just an orbital with 2 electrons.
Have a nice day!
