Explanation:
Hope it help
Answer:
a)
b)
c)
Explanation:
Given:
- mass of the object,
- height of the object above the spring,
- spring constant,
a)
When the object is dropped onto the spring whole of the gravitational potential energy of the mass is converted into the spring potential energy:
is the compression in the spring
b)
When there is a constant air resistance force of 0.6 newton then the apparent weight of the body in the medium will be:
Now the associated gravitational potential energy is converted into the spring potential energy:
c)
On moon, as per given details:
The supply of energy and of each needed chemical element restricts a system operation -- for example , without inputs of energy ( sunlight ) and matter ( carbon dioxide and water ) , a plant cannot grow. Hence , it is very informative to track the transfers of matter and energy within , into , or out of any system under study.
