its Dis it c?
what subject is this
physicswhat subject is this
Makes sense, but is a very wacky questionits D
it’s not c because it should be diffraction not dispersion, dispersion is to do with prisms and separating light into individual wavelengths
if for part C u used E = V/m, voltage is the total potential difference which determines how strong the E field is. whereas when calculating part A you’re interested in the change in potential between two points, hence why it would be 60V difference (eg point A is at 110V, point B is at 170V, so change in potential is 60V)Also for this q for part a you would say V=60 right since the particle only travels 3cm so you scale that accordingly to the potential diff [(100/5)×3=60] but how come for part c you let V=100 and D=0.05m? Because its released from position Y and travels towards the upper parallel plate so why doesnt V=80 and D=0.04m?View attachment 43967
hence, those options are not correctWhoever wrote that question about properties of water waves, they should be banned.
"Dispersion" is not caused by "waves bending around the edges of an object". That is a description of diffraction. "Superposition" is not caused by "waves bending near an object".
Dispersion is a change in the speed of waves due to a change in wavelength. A dispersive medium will cause a mixture of waves to separate according to their wavelength. For example, Crown glass is a dispersive medium, and a Crown glass prism causes white light to be dispersed into its separate colours. That question is rubbish.
thanks i thought i was stupid af for not understandingWhoever wrote that question about properties of water waves, they should be banned.

No. Read the second part of the questionshouldnt this be D not AView attachment 43983
Ohhh shit i accidentally put the 300 on the north part thats why, alr thank youNo. Read the second part of the question
The plane is supposed to angle itself to counteract the 100km/h crosswind from the east
Meaning sin(theta) = 100/300
Theta = 19.5
