Answer:
U_f = (U_o)/2)
Explanation:
The capacitance of a given capacitor is given by the formula;
C = ε_o•A/d
While energy stored in plates capacitor is given as; U_o = Q²/2C
Now,we are told that that all the dimensions of the capacitor plate is doubled. Thus, we now have;
C' = ε_o•4A/2d
Hence, C' = 2C
so capacitance is now doubled
Thus, the final energy stored between the plates of capacitor is given as;
U_f = Q²/2C'
From earlier, we saw that C' = 2C.
Thus;
U_f = Q²/2(2C)
U_f = Q²/4C
Rearranging, we have;
U_f = (1/2)(Q²/2C)
From earlier, U_o = Q²/2C
Hence,
U_f = (1/2)(U_o)
Or
U_f = (U_o/2)
Answer:
C
Explanation:
When a substance is changing state, the heat supplied does not result in a rise in temperature. This is why, the heat supplied during change of state is referred to as 'latent heat'.
Latent heat is a heat that causes a change of state without a corresponding rise in temperature. During this time, the intermolecular bonds in the substance are broken.
Change of state will occur as regions in which there is no change in temperature with time such as point D on the graph.
A scientific theory is an explanation of an aspect of the natural world that can be repeatedly tested and verified in accordance with the scientific method, using accepted protocols of observation, measurement, and evaluation of results. Where possible, theories are tested under controlled conditions in an experiment.
Answer:
Explanation:
Given that,
The uncertainty in the position of an electron along the x-axis is, 
We need to find the east uncertainty in any simultaneous measurement of the momentum component of this electron.
We know that the Heisenberg's uncertainty principle gives the relation between the uncertainty in position and the momentum of electron as :
Putting all the values, we get :
So, the momentum component of this electrons is greater than 
.
Im sure what is broken down is glucose.
