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.
for the stage one obese there are
many weight-loss strategies and programme accessible but many are not effective and it is short-term so the percent is lesser than 5
percent succeed in losing a significant amount of weight and maintaining the
weight loss with non-surgical programs — sometimes a combination of dieting,
behavior modification therapy and exercise. In particular it is a need to fucos
on behaviour modification before the diet and healthy proggrame.
A common theme in biology is that energy flows through biological systems while matter IS RECYCLED. Energy and matter are not destroyed in the ecosystem. The energy is transformed and the matter is recycled. In a food web, the food is transferred from one organism to another in different forms. this shows that the same molecules and atoms are recycled as the same molecule is used by one organism and then transferred to the second organism.
