potential energy
you have potential energy when you're stopped. you have kinetic energy when you're moving. so as you're going down a hill, kinetic energy is increasing and potential energy is decreasing.
Answer:
a. A hypothesis that does not generate a testable prediction is not useful.
Explanation:
In the scientific method, we generate a hypothesis to explain a phenomenon. After this, it is necessary to create a method to test the hypothesis and make predictions. Moving forward, we test this methodology, generating results and reject or not reject the hypothesis. If the hypothesis can't be tested, the scientific method can't be applied.
Earth's service would be bare. There would no longer be life and all water ways would become dried up due to the intense ultra-violent rays of the sun.
