c. II and III only (the object has 0 acceleration and the object has constant velocity.)
Why?
Let's discard each of the given options to find the correct one(s).
<h3>
- There are no forces acting on the object:</h3>
False, if an object has a constant speed, it does not mean that there are no forces acting on it, in fact, there will be always acting forces, like frictional force, gravity force, air resistance, and others.
<h3>
- The object has a 0 acceleration:</h3>
True, in an object is moving at constant speed, it means that there is no acceleration, the speed will be the same all the time during motion.
<h3>
- The object has constant velocity:</h3>
True, <u>if an object is moving in a straight line at constant speed</u> the velocity will be also constant. The velocity of an object is referring to its speed and its direction, if the object is moving in a straight line, the direction will be the same, so, if the speed is constant, the velocity will be also constant.
Have a nice day!

Answer:
nuclear fusion
Explanation:
The sun generates energy from a process called nuclear fusion. During nuclear fusion, the high pressure and temperature in the sun's core cause nuclei to separate from their electrons
Answer:
Astronauts float around in space because there is no gravity in space. Everyone knows that the farther you get from Earth, the less the gravitational force is. Well, astronauts are so far from the Earth that gravity is so small. This is why NASA calls it microgravity.
