Adhesion allows for it to be easily attracted to glass
Answer:
Gravity is measured by acceleration that it gives to freely falling objects . At Earth's surface the acceleration of gravity is about 9.8 meters ( 32 feet) per second per second. Thus, for every second an object is in free fall, its speed increases by about 9.8 meters per second.
Answer:
An experiment imposes treatment on the subjects, but an observational study does not
Explanation:
Observational studies are research studies in which an effect, process behaviour etc. are observed, without any change. For example, observation of the possible effect of a treatment on subjects.
On the other hand, experimental studies are studies in which the treatment is included. Experimental studies are randomized, meaning that subjects that are in experiment are randomly put to a treated group or a control group.
Explanation:
The ever and ever increasing demand for wood fuel, gas, timber, building materials, and many other consumer products are exerting more and more pressure on the earth’s natural resources, living organisms, and natural cycles responsible for maintaining a balance on earth.
Natural resources such as the water systems, fertile soil, clean air, vegetation cover, wildlife, indigenous plant species, and natural cycles such as the oxygen and nitrogen cycles, and food chains need trees for their continuity and balance.
