A0.14-kg pinecone is 16m above the ground. what is it’s gravitational potential energy

Given that:

mas (m) = 0.14 Kg ,

height (h) = 16 m,

     Determine gravitational potential energy ?

      Gravitational potential energy = m × g × h

                                                         = 0.14 × 9.81 × 16

                                                         = 21.97 Joules

answer: option c. i.e. electric current flowing “downhill” from the negative electrode to the positive electrode in a battery

explanation:

the water analogy to the circuits define the pipes (water flows) to the electric current. now, we know that the electric current flows from the positive terminal to the circuit (as shown in the diagram attached).

hence, option c is the correct answer.

well, you would divide 135 by 33 to get your answer. then that is how many seconds it would take. boardman should fly about 132 m or 4.090909090909091 seconds.
