On what does refraction depends
on frequency or wavelength?

Solve this????

Distance between t = 0 and t = 3 is 80 cm
The time taken is 2 s

So speed = 80/2
= 40 cm /s

100-20/2

Solve this????

Just make a circle around X that has A on its circumference. The direction of the arrows should be clockwise

DOES THE CONVECTION CURRENT IN THE HOUSEHOLD FRIDGE COMES??
what are the advantages of series circuit?
brightness depends on voltage or current?
can steel be magnetised by stroking method ?
when in cro the y plates are ac and timebase is off what kind of pattern would be formed?/
and does anyone have good notes on capcitior , led , potential divider??

 

[exploded diper]

yep

no i dun think so

 

[peacce]

no i dun think so

half ka milta hai i got it in bio

1) Cold air sinks to bottom as it has high density, Hot air rises to top as it has low density causing convection current.
2) Same current flows across each component. You need this for Simple Circuit Breaker. Batteries added in series voltage adds up.
3) Both
4) Yes
5) Point will move in middle of screen left and right as magnetic field changes.
