PART A)
Electrostatic potential at the position of origin is given by
here we have
now we have
Now work done to move another charge from infinite to origin is given by
here we will have
so there is no work required to move an electron from infinite to origin
PART B)
Initial potential energy of electron
Now we know
now by energy conservation we will have
So here initial total energy is sufficient high to reach the origin
PART C)
It will reach the origin
When the temperature lowers the plants can freeze and die. One way to prevent that is to cover the plants so they dont freeze
Answer:
Temperature
Explanation:
Heat only flows from one point to the other due to the difference in temperature.
It decomposes into CH3COO- and H+ when dissolved in water. The H+ ions react with the water molecules to generate H3O+, making the solution acidic. When NaOH is added to water, it separates into Na+ and OH-. The sodiums have little effect on the solution, but the hydroxyls make it more basic.
Answer:When white light strikes an object, each individual frequency of light is transmitted, reflected, or absorbed, depending on the properties of the surface molecules. If all frequencies are absorbed by the object, then it appears black. If all frequencies are reflected, then it appears white.
Explanation:
