Atomic number = number of protons
atomic mass = atomic number + number of neutrons
protons = electrons after ion effect
neutrons = atomic mass - atomic number
electrons = number of proton plus charge for -ve ion OR minus for +ve ion
They are different, representing different properties...
A) polyester, hope it was quick enough
We can apply Newton's third law of motion in roller coaster.
Explanation:
- If we are planning to make a roller coaster with elevations and turn then we need to apply newton’s law of motions, kinetic energy and potential energy.
- Newton’s third law of motion says that “ for every action, there is an equal and opposite reaction”. Newton’s third law of motion applies between the tract and ride vehicles.
- If we neglect the air resistance and friction, Roller coaster car will always experience two types of forces which are gravitational force and normal force. The normal force is acting perpendicular to the track and gravitational for is also acting downwards.
- Whenever the tracts get moving the gravitational force is attracting roller coaster to downward. So this will get accelerates. In the majority of the roller coasters, the hill will decrease with height as the train moves along the tract.
Answer:
Fossils are traces of organisms that lived in the past. When fossils are found, they are analyzed to determine the age of the fossil. The absolute age of the fossil can be determined through radiometric dating and determining the layer of rock in which the fossil was found.
