I believe we live in the Cenozoic era
We live in the Holocene Epoch, of the Quaternary Period, in the Cenozoic Era (of the Phanerozoic Eon).
Explanation:
The battery is a store of internal energy (shown as chemical energy). The energy is transferred through the wires to the lamp, which then transfers the energy to the surroundings as light. These are the useful energy transfers - we use electric lamps to light up our rooms.
<u>Answer
</u>
d. both the volume and the number of particles are constant.
<u>Explanation
</u>
Temperature increases the kinetic energy of the molecules. This increases the velocity of the molecules hence increasing the number of collisions with the walls of the container. This causes the pressure in the container to increase.
This will only happen if other factors are held constant. These factors are volume of the container and the number of particles/molecules.
Glass undergoes thermal expansion. The outer surface of the glass (with hot water) rapidly contracts when it is put inside the refrigerator. While the inner surface glass is still expanding because of the hot water. This causes the glass to crack.The reason would be C. the water has a larger coefficient of linear expansion than the glass. <span>Water expands significantly when it freezes.</span>
Answer:
Explanation:
We knwo that Kirchoff law
where
hence
C is given as 0.04\times 10^{6} F
L= 1 H , so we have
the characteristic equation of this differential equation is
Therefore differential equation is
we know initial value if capacitor is given as
Therefore
if no inital current is present then we hvae I(0) = Q'(0) = 0
therefre
hence charge is
