What is likely negative affect on the earth extra carbon dioxide is added to our atmosphere
konstantin123 [22]

Answer:

It will change weather patterns and destroy ecosystems.

Explanation:

Carbon dioxide, while not being the most power, is the most common greenhouse gas. A greenhouse gas helps to trap longwave radiation from leaving the Earth’s atmosphere and is enhancing global warming. We say enhanced global warming due to the Earth warming through natural reasons too. Several changes occur due to this temperature increase. Sea ice melting causes freshwater to enter the sea. An increase in sea levels can cause coastal flooding, increased erosion and a higher frequency and power of storms. Water density is linked to salinity. By introducing more freshwater the salinity decreases in the north and south of the Earth. If the oceanic currents change this will cause the weather to become more extreme during seasonal changes in many regions around the world. While humans can adapt their living conditions to suit the climate, many animals and plants can not. Therefore, enhanced global warming will cause the loss of many ecosystems around the world, including coral reefs.

A person weighing 0. 70 kn rides in an elevator that has an upward acceleration of 1. 5 m/s2. What is the magnitude of the force
damaskus [11]

The magnitude of the force of the elevator floor on the person is; 807.13 N

<h3>What is the Magnitude of force? </h3>

We are given;

Weight; W = 0.7 KN

Acceleration; a = 1.5 m/s²

There are only two forces acting on the person: which are his weight W (downward) and the normal force N of the floor against the body (upward). Thus the equilibrium equation here is;

N - W = F

N - W = ma

Here, m is the mass of body, and its value is calculated as;

W = mg

0.7 = 9.81m

m = 0.7/9.81

m = 71.42 kg

Thus;

N - 0.7 = 71.42 * 1.5

N = 0.7 + (71.42 * 1.5)

N = 807.13 N
