Answer:
3 meter / second square.
Explanation:
The acceleration is defined as change in velocity over a period of time interval. Mathematically it can be written as,
acceleration = change in velocity / time
acceleration = 16- 4 (meters/second) / 4 seconds
acceleration = 12 meters/second / 4 seconds
acceleration = 3 meter / second square.
So the answer shows that the car accelerates 3 meter / second square.
Answer:
DNA fingerprinting or DNA profiling technique
Explanation:
The DNA sequence is used in forensics to find the identity of a skeleton. A DNA profile is generated from the skeleton remains. The biological materials that can withstand exposure to intense environmental conditions such as heat, a significant amount of time passes are teeth and skeleton. So large quantities of DNA can be purified from these hard tissues.
B, if it has already been proven multiple time that something doesn't work why waste time doing the exact same thing and if you learn a bit more about the experiment it could change what you want to do.
Answer:
1-Wegener was a German meteorologist, geophysicist and polar researcher. In 1915 he published 'The Origin of Continents and Oceans', which outlined his theory of Continental Drift. Wegener was a member of four expeditions to Greenland.
2-The evidence for continental drift included the fit of the continents; the distribution of ancient fossils, rocks, and mountain ranges; and the locations of ancient climatic zones.
3-The movement of these tectonic plates is likely caused by convection currents in the molten rock in Earth's mantle below the crust. ... The long-term result of plate tectonics is the movement of entire continents over millions of years
