1- what is the speed of sound at moon give reasons
2- what is the time period of a geostationary satellites
3- an ice cube is floating in a glass of water what happens to the water level when the ice melts in my view the water level rises becaz glass is full of water and when ice melts the water level rises

(1)
There is no air on the moon and sound requires a material medium to travel. Thus, the sped of sound on the moon will be zero as no sound travels.
(2)
Time (or orbital) period of geostationary satellite is the same as the period of revolution of the Earth, 24 hours or 1 day.
(3)
If we drop a cube of ice in a glass of water then after the ice MELTS. The level of water remains the same. Because, apparent weight of ice = weight of the displaced water When ice melts, it occupies the volume of displaced water. So, water remains at the same level. Also we can say the density of ice is less than the water, so water level remains the same.
