Since ponds are typically shallower than lakes, this allows more sunlight to reach pond plants than lake plants. By getting my sunlight, these pond plants can photosynthesize more efficiently.
When the two hydrogen atoms bond with the oxygen, they attach to the top of the molecule rather like Mickey Mouse ears. This molecular structure gives the water molecule polarity, or a lopsided electrical charge that attracts other atoms.
Answer:
When a ball accelerates toward bottom it experiences both rolling friction and air resistance.
Explanation:
- When the ball rolls from the hill the gravitational force of attraction comes in action and accelerates the ball toward the bottom of the hill.
- This motion of ball is the rotational motion, rolling friction acts on it due to rotational motion.
- As the velocity of the ball increases air resistance also starts to have significant effect on its motion.
- These two forces try to oppose the motion of the ball.
