Kinetic energy is energy that a body possesses by virtue of being in motion, there for if an object is moving, it has kinetic energy.
Example; A roller coaster sitting on top of hill has potential energy. When it starts to move and is going down the hill, it has kinetic energy. :)
Answer:
All of the above
Explanation:
The correct answer is option E (All of the above)
All the options are alternative source of energy.
The option given are not the traditional way (energy production from coal) of extracting energy as the loss of natural resources does not take place in these source of energy.
energy extracted from wind, solar light , hydrogen ,etc are the source of energy the alternative source of production of energy because do not exploit the natural resources, reduce the carbon emission and energy produced by them is clean energy.
Answer:
Explanation:
I = Moment of inertia =
m = Mass of two atoms = 2m =
r = distance between axis and rotation mass
Moment of inertia of the system is given by
The distance between the atoms will be two times the distance between axis and rotation mass.
Therefore, the distance between the two atoms is
To solve this problem it is necessary to apply the concewptos related to Torque, kinetic movement and Newton's second Law.
By definition Newton's second law is described as
F= ma
Where,
m= mass
a = Acceleration
Part A) According to the information (and as can be seen in the attached graph) a sum of forces is carried out in mass B, it is obtained that,
In the case of mass A,
Making summation of Torques in the Pulley we have to
Replacing the values previously found,
Replacing with our values
PART B) Ignoring the moment of inertia the acceleration would be given by
Therefore the error would be,
