Answer:

2.1J

Explanation:

Given parameters:

Mass of pendulum  = 0.7kg

Height of pendulum = 0.3m

Acceleration due to gravity  = 9.8m/s²

Unknown:

Potential energy of the pendulum  = ?

Solution:

The potential energy of a body is the energy due to the position of that body;

 Potential energy  = mass x acceleration due to gravity x height

Insert the parameters and solve;

Potential energy  =0.7kg x 0.3m x 9.8m/s²  

 Potential energy  = 2.1J

Which of the following statements is CORRECT?a. A hypothesis that does not generate a testable prediction is not useful.b. Commo
Fofino [41]

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.
