A10 once glass of water (half full) is initially at 15c. it is left outside overnight in a location where the air temperature is -5c. by morning the glass is in equilibrium with the surroundings. find the change in entropy of the water, the surroundings and the universe for this process.

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

hi,

the moon is between earth and the sun.

p.s. im not sure if the first answer is correct because during a solar ecliphse there are spring tides and i dont know if they are the same.
