E p = m · g · h
E p ( book ) = 0.35 kg · 9.8 m/s² · 2 m = 6.86 J
E p ( picture frame ) = 6.86 J
( same gravitational potential energy as the book )
6.86 = 0.5 · 9.8 · h
6.86 = 4.9 h
h = 6.86 : 4.9
h = 1.4 m
Answer: ... to a height of 1.4 m.
Answer:
The correct answer is inertia.
Explanation:
Inertia is called in physics the resistance that bodies oppose to modify their state of motion or stillness, either to alter their speed, their course or to stop; although the term also applies to the modifications of your physical state.
A body, thus, requires a force that overcomes inertia to alter its trajectory, which would otherwise adhere to the laws of uniform rectilinear motion, or to initiate a movement, otherwise it would remain at rest. This, of course, considering that there is no rest or rectilinear and uniform movement in the universe, except based on a reference (observation) system. That is why it is preferred to speak of "relative rest."

<h3>Administrative purposes </h3>
Administrative purposes means any purpose necessary for the operation and proper functioning of the administrative, educational and medical services carried out by an approved developer in a zone.
Administrative purposes include administrative issues, including the working of the corporations, funding from the State government, disbursement of counsillor funds and shortage of staff, got about two to three times more attention than solid waste management, education and health.

<span>Selection C is the most appropriate. By establishing credibility at the outset of your proposal, you can make it clearer that you understand the scope of the problem you're trying to solve. This can also make is easier for your supervisor to develop questions that he or she may have as a way of teasing out some more specifics about your plans and suggestions.</span>
