property of gas
gas molecules are very loosely bonded with each other so the force between the molecules is very weak
Due to this weak force the molecules of gas can attain any shape and any volume.
So gas moles have no finite shape and no finite volume
Property of Solids
Solids are tightly packed and having very strong bond between the molecules
If all molecules are tightly bonded then they have always a finite shape and finite volume so in this case we can not change the volume or shape of the solids as it is fixed.
Property of Liquids
Liquid molecules are moderately bonded together and since the force is more than the force between the gas molecules so liquids have finite volume but indefinite shape
liquid attains the shape of the container but its volume is fixed
So in above all examples Liquid is correct answer
Magnetic fields can go through some materials (like cardboard). Electric fields can also do that. Electromagnetic waves can do that. It’s not at all unusual because magnetic fields are not made up of particles so they can go through materials.
T is the time for a whole round.
centripetal acceleration = V^2/R,
20 = 40^2 / R, find R = 40^2/20 = 40*40/20 = 80 m, right?
Now, one round is L = 2*pi*R = 2*pi*80 = 160*pi
And T = L/v (distance/speed) = 160*pi/40 = 4*pi seconds, or ~ 12.57 s
Answer:
5km
Explanation:
Magnitude of displacement is found by getting the resultant. Resultant is same as the bypotenuse hence
where x is the displacement in west direction and y is displacement in North direction. Substituting x with 3km and y with 4 km then
Explanation:
1. Mass of the proton, 
Wavelength, 
We need to find the potential difference. The relationship between potential difference and wavelength is given by :
V = 45.83 volts
2. Mass of the electron, 
Wavelength,
We need to find the potential difference. The relationship between potential difference and wavelength is given by :
V = 84109.27 volt
Hence, this is the required solution.
