I would say the answer to your question is A Ferris wheel turning at a constant speed. The reasoning behind this answer is the fact that traveling in a constant direction at a constant speed is not accelerating. The Ferris wheel is the only option that fits this description. The last option would be incorrect due to independent causes such as speed limit changes as well as turns and stops on the highway.
600 watts may be your answer:)
Explanation:
Gas pedal is not required to used on friction less surface. On a friction less surface once the car is started and caused to move, car continues to move with same velocity as there is no opposing force. Therefore, no pressing of gas pedal required. However, this situation is not possible in real life, as friction is always present.
I think the correct answer would be option C. Adding one proton to an atom of lithium with 3 protons, 4 neutrons and 3 electrons would form a beryllium ion. The new atom have 4 protons and 4 neutrons since Be has a mass number of 9 then it has to form an ion.
