Answer:
because they are both a kilogram
Explanation:
Answer:
E = 0.08
J
Explanation:
Given that,
The elastic potential energy of the spring is given by :
Where
k is spring constant
x is compression in the spring
We need to find the energy stored when force constant is 400 N-m and the compression is 0.02 m.
So, the required energy in the spring is equal to 0.08 J.
<span>Avogadro's number
represents the number of units in one mole of any substance. This has the value
of 6.022 x 10^23 units / mole. This number can be used to convert the number of
atoms or molecules into number of moles. We calculate as follows:
</span>2.0*10^18 molecules of water ( 1 mol / 6.022 x 10^23 molecules ) = 3.32x10^-6 mol water
Answer:
In the roller coasters the potential energy that is given is the gravitational potential energy, which this energy increases its value as the object moves away from the earth, that is to say, the more height the roller coaster acquires the more gravitational potential energy it will have, and Said train where people usually get on the roller coaster will descend or descend with greater acceleration.
This gravitational potential energy once the mountain begins to descend or descend is converted into kinetic energy
Explanation:
This that we wrote above is considering that the roller coaster does not have curved routes but rectilinear, in the case that it had curved routes, a force would be added in addition to those written that is the centripetal force, it is the same force that appears in the centrifuges or dryers of clothes or the same washing machine. This force, the centripetal force is the force that draws a moving object, in a curvilinear path, towards the center of the curvature.
Answer:
Each time you exhale, you are releasing carbon dioxide into the atmosphere. Animals and plants get rid of carbon dioxide gas through a process called respiration. Carbon moves from fossil fuels to the atmosphere when fuels are burned.
