Answer:
The bicycle slows down because of the frictional force acting on the tyres of the bicycle. When this frictional force overcomes the force applied by paddling, the bicycle stops.
Correct answer is option A.
Tropopause, Stratopause and Mesopause have all in common aspect that is point of maximum temperature in its layer of the atmosphere. All layers of atmosphere observe abrupt change in temperature. Tropopause is the boundary between Troposphere and Stratosphere. Stratopause is the boundary between Stratosphere and Mesosphere. Mesopause is the boundary between Mesosphere and Thermosphere. These all boundaries are ranges between altitude of 0 to 80 km.
Answer:
3.) scientific field that uses technology to purposefully change living things
Explanation:
Science can be defined as a branch of intellectual and practical study which systematically observe a body of fact in relation to the structure and behavior of non-living and living organisms (animals, plants and humans) in the natural world through experiments. One of the most important branch of science is bioengineering. Biotechnology can be defined as a high-tech process which avail scientists the opportunity or ability to modify, remove, replace and insert Deoxyribonucleic Acid (DNA) sequence in a living organism such as bacterias, animals, plants etc in order to correct a genetic disorder and to improve on their physical and chemical conditions.
For example, selective breeding also referred to as artificial selection is being used to create plants that are more resistant to certain biological diseases. Thus, this is an example of an organism being changed through technological methods commonly known as biotechnology.
Hence, the phrase which best defines biotechnology is that, it is the scientific field that uses technology to purposefully change living things.
Answer:(a) 8.33m/s
(b) 1.11m/s^2
Explanation:
By using the equation of motion for the problem,
Given that V=15m/s U=?(unknown) t=6.0s S= 70m
By definition, distance is the product of the average velocity and time
From S=[(u+v)/2]xt
By substitution, 70 =[(U+15)/2]x 6
U=8.33m/s
By using V=U+at
15=6.66+6a
By substitution, acceleration=1.11m/s^2
The "D) People perceive objects as a whole" statement best describes an abductive reasoning. The abductive reasoning often has incomplete information as the base of its reasoning and the conclusion for this type of reasoning is not absolute. There will always be additional pieces of evidence and factors that could change the conclusion of this reasoning. Therefore<span> D statement is the most suitable answer.</span>
