Explanation:
The moment of inertia of each disk is:
Idisk = 1/2 MR²
Using parallel axis theorem, the moment of inertia of each rod is:
Irod = 1/2 mr² + m (R − r)²
The total moment of inertia is:
I = 2Idisk + 5Irod
I = 2 (1/2 MR²) + 5 [1/2 mr² + m (R − r)²]
I = MR² + 5/2 mr² + 5m (R − r)²
Plugging in values:
I = (125 g) (5 cm)² + 5/2 (250 g) (1 cm)² + 5 (250 g) (5 cm − 1 cm)²
I = 23,750 g cm²
Answer:
Cations (positively-charged ions) and anions (negatively-charged ions) are formed when a metal loses electrons, and a nonmetal gains those electrons. The electrostatic attraction between the positives and negatives brings the particles together and creates an ionic compound, such as sodium chloride.
Explanation:
Electric potential energy will be transformed into kinetic energy.
Answer: The particle model, because only high-energy frequencies of lights can remove electrons.
Explanation: just did the test and got it right :)
It can be done by you only as we can't access those data in documents.
Let me show steps
- Read the introduction first.
- See below there are two documents in blue
- Lab report guide
- Lab report public
- Use first one in order to prepare the lap report guide
- Use second one in order to public them .
- Submit all files at add file option.
