Question

practice it! analyze the forces that are acting on the airplane as seen on the right all of the following are examples of gravity being exerted on objects of different masses, except: the sun someone riding a bike a person diving off a diving board an airplane flying through the air

Explanation:

Gravity is the force that attracts objects with mass towards each other, typically towards the Earth (or other massive bodies). For someone riding a bike, a person diving, and an airplane flying, gravity acts on them (pulling towards Earth). The Sun exerts gravitational force on other celestial bodies (like planets), but the question is about gravity exerted on these objects (the bike - rider, diver, airplane) or the Sun's own gravity? Wait, no—wait, the options: the Sun is a massive object exerting gravity on others, but the other options are objects (bike - rider, diver, airplane) being acted on by Earth's gravity. Wait, no—actually, the Sun's case: the question is "examples of gravity being exerted on objects of different masses"—so the Sun is a source of gravity, but the others are objects being acted on by gravity. Wait, no, let's re - analyze. Gravity acts on all objects with mass. But the Sun: is the Sun an example of gravity being exerted on it? No, the Sun exerts gravity, but the question is about gravity being exerted on the objects (the Sun as an object? Wait, no. Wait, the other options: someone riding a bike (gravity acts on the person and bike), a person diving (gravity acts on the person), an airplane flying (gravity acts on the airplane). The Sun: gravity is exerted on the Sun? No, the Sun is a massive body that exerts gravity on other objects. Wait, maybe the confusion is: the Sun is a celestial body, and the question is about gravity acting on the listed objects (the bike - rider, diver, airplane) or the Sun. Wait, no—all objects with mass are subject to gravity. But the key is: the Sun is a source of gravitational force for other objects, but the other options are objects on which gravity (from Earth, mostly) is acting. Wait, no, actually, the Sun also has gravity acting on it? No, gravity is a mutual force, but the question is about "gravity being exerted on objects"—so the Sun is an object, but the gravity exerted on the Sun would be from other celestial bodies (like the Milky Way's center), but the other options are objects on which Earth's gravity is acting. Wait, no, maybe the answer is the Sun. Because the other three (bike - rider, diver, airplane) are objects on which Earth's gravity acts, while the Sun is a massive body that exerts gravity, and the gravity exerted on the Sun is not the same context as the others (the others are on Earth - bound objects). So the exception is the Sun.

Answer:

the Sun
