Answer:
The positive impact in the cycle is that CO2 will make plants to use water more efficiently and also thereby make them to become drought resistant and thereby grow faster.
Explanation:
Carbon cycle is the process by which carbon dioxide travels from the atmosphere to the earth and returns back to the atmosphere.
The negative impact of carbon dioxide in the carbon cycle is that it will cause green house effect. However, when it comes to the positive impact in the cycle, CO2 will make plants to use water more efficiently and also thereby make them to become drought resistant and thereby grow faster.

Answer:
The height reached by the dart in the second shot is (4 H).
Explanation:
It is given that, a spring-loaded toy dart gun is shot to a height h. In this case, all the potential energy stored in the spring is converted to potential gravitational energy at the maximum height.
........(1)
At the second shot, the spring is compressed twice as far before firing. x' = 2x

.........(2)
h is the height reached by the dart in the second shot.
Dividing equation (1) and (2) as:

h = 4H
So, the height reached by the dart in the second shot is (4 H). Hence, this is the required solution.
