Answer: When a cat drops from a tree to the ground, the conversion of gravitational potential energy to kinetic energy takes place. Then runs up behind a mouse to obtain its food. After eating its prey, the conversion of chemical energy to mechanical energy takes place inside the cat's body.
Explanation:
Given: The population density of frogs in a portion of a pond is 12 frogs per square meter. The size of the entire pond is 370 square meters.
To find: The total population size of the frogs in the pond.
Method: Using unitary method of proportions
Solution:
Let p be the density of the frogs present per square meter.
Let A denote the total area of the pond.
∴ p = 12 frogs/m² and A = 370 m²
The total number of frogs in the pond is given by,
Therefore, there are 4440 frogs in the pond.
