Answer:
V=14
Explanation:
PE=KE
mgh=1/2mv^2
2(9.8)10=1/2(2)v^2
(radical) 196= (radical)v
V=14

Answer
Correct Answer is C (10% of the plant's energy is transferred
Explanation:
Ecosystem
ecosystem is a community where large number of living organisms lives. These living organism are plants, trees, different types of animals, birds etc. These living organism depends on each other for their food.
Their are various levels in ecosystem like producer, primary consumer, secondary consumer and tertiary consumer.
producer like plants produce their food on their own. And primary consumers takes their food from producers.
According to 10% Rule of ecology only 10% energy is passed from one level to another.So 10% of the plant's energy is transferred
Then, the reaction does not have any kinetic energy
