Answer: A. The extra electrons start to fill higher sublevels in the energy level.
Explanation:
It is true that human impact on one system leads to changes in more of Earth’s systems.
Answer: Option A
<u>Explanation:</u>
Human impact had created large impacts on Earth’s systems. The pollution in air, deforestation, dumping of lakes lead to several changes in environment. Also emission of carbon, methane and other hazardous gases from several manufacturing unit effect the environment.
Along with this, increase in usage of non-renewable fuels and release of CFC's emitted from AC’s, fridge lead to elimination of ozone layer making the environment open to direct UV radiation. So yes, it is true that human impact on one system leads to changes in more of Earth’s systems.
Answer:
B) microscopic
Explanation:
A scanning tunneling microscope allows imaging of microscopic particles.
Answer:
c) (12×0.9889) + (13×0.01108)
Explanation:
Given data:
Percentage of C-12 = 98.89%
Percentage of C-13 = 1.108%
Atomic mass = ?
Solution:
98.89/100 = 0.9889
1.108/ 100 = 0.01108
Atomic mass = (12×0.9889) + (13×0.01108)
Atomic mass = (11.8668 + 0.144034)
Atomic mass = 12.01084
Answer:
Torrey's neighbour is incorrect because increase in kinetic energy is proportional to velocity. If the velocity increases so will the object's kinetic energy. Because the mass is constant, if the velocity increases, so does the kinetic energy.
