Answer:
El material del calorímetro es aislante, conducción térmica entre sustancias y alrededores casi nula.
Explanation:
Es posible suponer que la energía térmica que gana el agua en un calórimetro equivale a la energía térmica perdida por la muestra que se prueba, en tanto que el material del calorímetro se caracteriza por ser de naturaleza aislante, es decir, que no permite las interacciones de energía entre los fluidos al interior y los alrededores del calorímetro.
Answer:
a) Energy stored in the capacitor,
b) Q = 45 µC
c) C' = 1.5 μF
d)
Explanation:
Capacitance, C = 1 µF
Charge on the plates, Q = 45 µC
a) Energy stored in the capacitor is given by the formula:
b) The charge on the plates of the capacitor will not change
It will still remains, Q = 45 µC
c) Electric field is non zero over (1-1/3) = 2/3 of d
From the relation V = Ed,
The voltage has changed by a factor of 2/3
Since the capacitance is given as C = Q/V
The new capacitance with the conductor in place, C' = (3/2) C
C' = (3/2) * 1μF
C' = 1.5 μF
d) Energy stored in the capacitor with the conductor in place
Answer:
Static electricity.
Explanation:
Static electricity is caused by an imbalance between negative and positive charges in an object. Charges build up on the surface of an object till they are released or discharged.
Rubbing materials against one another can transfer negative charges, or electrons. Examples of these materials are; glass rod on silk cloth, wax on wool cloth, wax on glass rod etc.
