Explanation

• An object moving along a circular path is experiencing a change in direction, which means it is constantly accelerating.
• According to Newton's first law of motion, an object in motion will remain in motion with a constant velocity unless acted upon by an external force.
• In the case of an object moving in a circular path, the force of centripetal acceleration is acting on the object, causing it to change direction and accelerate towards the center of the circle.
• Therefore, the object is not in equilibrium.

Explanation

• Prototyping is a software development methodology that involves creating a working model or a mockup of a system or application to test and refine its requirements and design.
• In prototyping, Fourth-Generation Languages (4GLs) are often used.
• 4GLs are high-level programming languages that provide a more abstract and visual way of programming, making it easier to quickly build and test prototypes.

Explanation

• Pseudonym: a fictitious name, especially one used by an author.
• Nickname: a familiar or humorous name given to a person or thing instead of or as well as the real name.
• Nomenclature: the devising or choosing of names for things, especially in a science or other discipline.
• Title: a name that describes someone's position or job.

Explanation

• In C, the For loop is commonly used to iterate through an array because it allows for easy initialization, condition checking, and incrementing/decrementing of the loop counter.
• The syntax of a For loop is designed to handle array indexing and iteration naturally.

Explanation

The maximum value that can be stored in an "int" data type in C++ is 2147483647.

Explanation

Nitrogen is an important mineral nutrient for plants and is essential for their growth and development. 

Explanation

The percentage of a sample of HBr decomposes at 430 °C. is 0.1.

Explanation

• Speleology is the scientific study and exploration of caves.
• The word comes from the Greek words "spelaion", meaning "cave", and "-logy", meaning "study" or "science".

Explanation

• As the number of protons (atomic number) increases, the ionization energy also increases.
• This is because the positive charge of the nucleus increases, which pulls the electrons closer to the nucleus, making it harder to remove an electron (i.e., higher ionization energy).

Explanation

Cyclic AMP is a second messenger molecule that is involved in intracellular signaling pathways, not extracellular signaling.
