Diagram shows a wilted plant. Which of the following is the inference about the condition of the plant?

• The plant needs water to stay alive.

• The plant will die after two days.

• The plant wilted because of no water.

what is the hypothesis of this experiment?

• As the length of pendulum increases,

  the time taken for 10 complete oscillations also increases.

• As the length of pendulum increases,

  the time taken for 10 complete oscillations decreases.

• the time taken for 10 complete oscillations decreases.

what is the aim of this experiment?

• As the length of pendulum increases,

  the time taken for 10 complete oscillations also increases.

• To investigate the relationship between the length of pendulum and time taken for 10 complete oscillations.

• The time taken for 10 complete oscillations decreases.
