As per the existing knowledge the light bends due to the curvature of space time near gravitating body like sun. But we know that sun is a huge body of gas. we know that light chages its path as it passes through a chaging refractive index. Isn't it due to the suns atmosphere that light bend?

have one person seated on a stool, have four other people place their index fingers (extended) under each arm pit and under each knee. at the count of 3 try lifting this person off the chair. Very difficult, now place all hands on top of seated persons head with a slight pressure, now simultaneously repeat the above proceedure and you will find that it is very easy to elevate the seated person.
NOw has anyone an explanation as to why this is possible?

A car traveling at a speed of vo = 57 m/s stops smoothly (that is, its deceleration is constant) over a distance of d = 110 m.

a) What is its acceleration during the time it is stopping?
b) How long (what amount of time) does it take for the car to come to a stop?
c) After the car has gone 1/3 of the stopping distance, what is its speed?

In certain cases, we can relate the value of q to the change in volume of a system and so can calculate, for instance, the flow of energy as heat into the system when a gas expands. The simplest cas is that of a perfect gas undergoing isothermal expansion. Because the expansion is isothermal, the temperature of the gas is the same at the end of the expansion as it was initially. Therefore, the mean speed of the molecules of the gas is the same before and after the expansion. That implies in turn that the total kinetic E of the molecules is the same. But for a perfect gas, the only contribution to the energy is the kinetic E of the molecules; so, we have to conclude that the total E of the gas is the same before and after the expansion. E has left the system as work; therefore, a compensating amount of E must have entered the system as heat. We can therefore write "For the isothermal expansion of a perfect gas: q = -w "

Physical chemistry book gives an example of a closed system of gas being heated, but then expanding a piston outward in a cylinder, performing work on the surroundings. It uses this as an example of an isothermal expansion (stating that isothermal means temp of gas is same initial and final). My understanding: But if PV=nRT, and n is UNchanged, then an increase in V (from heating) must be accompanied by an increase in T!!!

Recently, my aircon was not cold and I discovered a lot of ice on the evaporator coil (too much condensation).When I called service man to check he just top up the gas and it was ok.I am puzzeling why the ice form when the gas amount was lesser.Is it due to more pressure difference of high side and low side?

I have a thoery of dark matter, and intelligent of many answers of a lot of Ghost or spirit sightings, i believe dark matter excists in the earths atomosphere.
Black hole example it can consume thousands of planets.
when consumed nobody at the present day can say where these planets go?
within the consumption of the planets dark matter is the Most of the black hole?
Correct me if i am wrong????
So when the black hole consumes, when earth was formed. Dark matter was in the mix.
Dark matter is nothing, no atoms just black nothing.
But has wieght............ A teaspoon of it would not be able to pick up.
Is this true about the weight? and what do you think of my thoery
