Final answer:
Charging by polarization does not always require contact (false), wave-particle duality isn't applicable on a macroscopic scale (false), polarized insulating objects won't depolarize just by touching (false), angles alone don't determine the resultant vector's angle (false), and a hypothesis is most similar to a suggestion.
Step-by-step explanation:
The question is asking about several concepts related to physics, specifically electrostatics and vector addition. Let's go through the statements one by one:
- Charging an object by polarization does not necessarily require touching it with an object carrying excess charge. This process can also happen when the object is brought near a charged object, causing a separation of charges within the object without direct contact. Therefore, the statement is false.
- Wave-particle duality is a principle in quantum mechanics that states particles can exhibit both wave-like and particle-like properties. However, this phenomenon is significant only at the quantum level (for very small particles) and not on the macroscopic scale we observe in everyday life. Hence, the statement is false.
- For two insulating objects that are polarized, simply touching them together typically won't cancel the polarization. The polarization could be due to induced charges, and connecting the objects might redistribute the charges but won't necessarily neutralize them. The statement is therefore false.
- In terms of vector addition, knowing just the angles of two vectors is not enough to find the resultant vector's angle. You also need to know their magnitudes. This statement is false.
When comparing the words hypothesis to the others listed (fact, law, formula, suggestion, conclusion), a hypothesis is closest in meaning to a suggestion. A hypothesis is an educated guess or proposed explanation made on the basis of limited evidence as a starting point for further investigation, which aligns with the idea of a suggestion.
