So is there a way by which radiation outside to surrounding can be blocked for the question to be valid?

The figure is infinite out and in the page. We need to find $$f_{ij}$$ means if $$I$$ is the total radiation plate i is emitting then $$f_{ij}$$ represent fraction of total radiation Falling on plate $$j$$ from plate $$i$$ $$So in general fab represent fraction of total radiation from a...

One more thing is center of mass frame is still zero momentum frame when it is non inertial? Like I can't conserve momentum when is is non inertial.

So in cm frame all the kinetic energy is converted to potential energy , then why does in ground frame all the kinetic energy is not converted to potential energy of the system, are there any restriction? Or is it to do with the system as block leaves the bowl and not net horizontal force in x...

So giving two examples where this happens Example 1 Consider a hemispherical bowl and a block placed inside it if the bowl is given velocity v𝑣 and given that there is no friction, the block will gain kinetic energy and then will rise to a maximum height h both the bowl and block will have same...
