Answer:
go to a calculator and see the answer then make the hypothisis which is the answer
Explanation:
magic
Remeber:
Kinectic energy = [1/2]mv^2
Potential energy = m.g[h - h0]
6. When the snowboarder is still at the top, she does not have kinetic energy, given that the speed is zero.
There, at the top, the potential energy is maximum, given that the height, h - h0, is the highest.
So, ar the topo she only has potential energy.
7. From that point, the snowboarder, starts to gain velocity; is has started a process of conversion of potential energy to kinetic energy. More velocity, less height, more kinetic ener energy and less ptential energy.
At the very bottom, when she has reached the heigth of reference, h0, the term [h - h0] becomes zero, then the potential energy has dissapeared and all the energy has been transformed into kinetic energy; the speed and the kinetic energy are maximum.
Answer:
Extensive properties depend on de mass, intensive properties not.
Explanation:
The extensive properties depend on the mass and change with the addition or reducction of the mass.
The intensive properties dont depend on the mass. For example: temperature.
I hope I help you.
I think the correct answer from the choices listed above is option B. The following reaction does not proceed to form a product: H2O + Au---> no reaction because gold has a lower activity than hydrogen and cannot replace it. Hope this answers the question.
