Answer:
a)
b)
c) displacment = 400nm
Explanation:
Given that
charge of the electron and proton
the distance between electron and proton = 2.0 nm
The force between the proton and electron
Here
The work done in displacing the electron from 2.0 nm to 12 nm
is the minimum kinetic energy
W = F .s
(b)
If this energy is the kinetic energy of the electron
Here m is the mass of the electron =
The speed of the electron
(c)
If the kinetic energy is twice the initial kinetic energy
2*(initial kinetic energy) = F*displacement
displacement = 2*(initial kinetic energy)/F
Displacement =
displacement = 400 nm
To be able to classify which species is which
The chemical and physical actions of groundwater form Karst topography. It is <span>any region where the terrain has been dissolved by the physical and chemical weathering of the bedrock.
There is no reason why glaciers, volcanoes, and mountains should be formed as a result of these actions. </span>
Well, if the bag is moving across the floor at a constant velocity. Then I would assume that the Fnet force is equal to 0, and thus the value of acceleration would also be equal to 0.
Answer: 8400 J
Explanation:
The formula referenced in the question is:
Where:
is the thermal energy
is the mass of the water sample
is the specific heat capacity of water
is the variation in temperature
Solving:
This is the thermal energy released
