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.
Weather can differ and change with climate and can almost change suddenly. Erosion is wear from the surface or areas over time.
The larger the solute the slower the rate of diffusion. Smaller the solute, faster the rate of diffusion. If the shape of the solute has a large surface area then it'll have the faster rate of diffusion. Shape of solute that has a small Surface area, has a slower rate of diffusion
