La energía cinética se define como:
⇒
mi
k
=
1
2 metro v2
Dado que la masa del péndulo no cambiará, la única forma de que cambie la energía cinética es que cambie la velocidad del péndulo. La energía cinética es máxima cuando la velocidad es máxima. Esto ocurre en la parte inferior del péndulo.
B
.
Si la energía cinética es más alta en la parte inferior del péndulo, entonces es donde la energía potencial es la más baja. Entonces, la energía potencial sería más alta cuando el péndulo esté en su punto más alto a cada lado de su movimiento donde está estacionario por un instante. Este es el punto donde toda la energía cinética se ha convertido en energía potencial (

Depending on what water source you use, if your using faucet water your food will be clean but not totally.
If your using a lake, ocean, bodies of water your food will not be as clean, water from bodies of water are full of bacteria, and other contaminants.That being said, using a faucet is your best bet or even try to clarify water from bodies can help.
What makes people healthy can be the type of food they eat such as salad, vegetables and other foods. What makes people unhealthy is when they eat junk food or they eat fast food everyday. I am not saying that to offend anyone. It is just how their parents feed their children to eat the right food to live a healthy lifestyle. It is not only that people are healthy physically. It is also by trusting God with all of your heart. If you don't believe in God, that's okay. Other people exercise so they can lose weight. That is how people can people can be healthy and how people are unhealthy. I am not too sure how to explain the second question but I hope this answer helps you :)
