Answer:
benefits
Diversifying energy supply and reducing dependence on imported fuels.
Creating economic development and jobs in manufacturing, installation, and more.
drawbacks
Large areas of landfill are required
Hydroelectric power is generated from flowing water, which turns turbines and generates electricity
Explanation:
The acceleration of the first block (4 kg) is -9.8 m/s².
The given parameters:
- <em>Mass of the first block, m₁ = 4.0 kg</em>
- <em>Mass of the second block, m₂ = 2.0 kg</em>
The net force on the system of the two blocks is calculated as follows;
![m_2 g - T = m_1 a](https://tex.z-dn.net/?f=m_2%20g%20-%20T%20%3D%20m_1%20a)
where;
- <em>T </em><em>is the tension in the connecting string due weight of the first block</em>
![m_2 g - m_1 g = m_1 a\\\\a = \frac{m_2 g - m_1g}{m_1} \\\\a = \frac{g(m_2 - m_1)}{m_1} \\\\a = \frac{9.8(2-4)}{2} \\\\a = -9.8 \ m/s^2](https://tex.z-dn.net/?f=m_2%20g%20-%20m_1%20g%20%3D%20m_1%20a%5C%5C%5C%5Ca%20%3D%20%5Cfrac%7Bm_2%20g%20-%20m_1g%7D%7Bm_1%7D%20%5C%5C%5C%5Ca%20%3D%20%5Cfrac%7Bg%28m_2%20-%20m_1%29%7D%7Bm_1%7D%20%5C%5C%5C%5Ca%20%3D%20%5Cfrac%7B9.8%282-4%29%7D%7B2%7D%20%5C%5C%5C%5Ca%20%3D%20-9.8%20%5C%20m%2Fs%5E2)
Thus, the acceleration of the first block (4 kg) is -9.8 m/s².

Answer:
Personally I think, that the answer is B.
Explanation:
Answer:
this is your choice entirely but anyways
professionalism so they don't slack off
respect so they can be respected while treating others with respect
kindness (even if only a little) so they aren't plain out rude
if they're in school, passing grades so they can be taken seriously
role model so they can teach younger people
