Which form of energy increases when a spring is compressed? a. chemical potential energy b. elastic potential energy c. kinetic energy d. radiant energy e. thermal energy

Elastic potential energy

Explanation:

The potential energy of a spring is given by :

..........(1)

Where

k = spring constant

x = compression or elongation in the spring

When the spring is compresses, elastic potential energy of the spring increase. From equation (1), it is clear that the elastic potential energy of spring is directly proportional to the compression or elongation in the spring.

Hence, the correct option is (b) "elastic potential energy".

there are 35 white marbles

step-by-step explanation:

y- yellow marbles

4y + 5 = 45

subtract 5 from both sides

4y = 40

divide for from both sides

y = 10

plug in 10 to get 40 yellow marbles then subtract by 5 to get 35 marbles

thus there are only 10 yellow marbles
