a steel ball bearing will drop faster in warm water then cold water, a beach ball will float better in cold water because cold water is more dense.
If you drop it and it rolls back into the water, you take another free drop, if this rolls back into the water you place the ball where it touched the ground on the second drop. Remember, no nearer the hole.
The ball which you drop from 5 feet will reach the ground first.
You drop it once, if it comes to rest on the path, you drop it again, on the second drop if it comes to rest on the path you place it where the ball touched the grass first on the second drop.
cold water
The ball would be dropped at the point of impact no closer to the hole, unless there is a designated "Drop Area". If there is not the player is to drop their ball, and if it rolls back into the water this step is repeated. If it rolls back in again, then the ball is placed at point of impact.
you hit the ball towards the flag. But if it goes in a water hazard, you drop before the water.
The only thing to be gained from casual water is a free drop. You find your nearest point of relief, no closer to the hole and drop the ball in the usual way.
Since the rate of acceleration due to gravity is equal for all objects, the ball you drop first will most likely bounce first.
The ball is played from where it stops. If you can't hit it out of the hazard, take the drop and penalty.
My fiance and I did an experiment with hot and cold water to see which one would make ice cubes faster. Honestly they froze at about the same time. He was taught that because its hot the molecules come together faster in the cold air, but during the test it was equal. As for the salt water I would think that would come in last.
Drop the big silver ball up by the red first. Then you wait for the wedge to stop wiggling. Then drop the wedge. Then let the swinging green ball fall towards the yellow. If you get lucky the green balls will both go it the vase. If they don't, drop the yellow ball, and then the other big silver one. Finally, drop the last silver ball.
If you drop the ball when you're playing golf in the water you get a penalty
