Answer:

<h2>A. The mechanical energy transforms to thermal energy as the pendulum slows and eventually stops moving.</h2>

Explanation:

The law of conservation of energy states that the amount of energy is a constant, that is, it cannot be created or destroyed, it just can be transformed into different forms.

For example, in real life, a pendulum will stop moving eventually. But, why is the pendulum going to stop? Because, there's friction in that motion, which means that the energy that's being used, it's transforming into heat by friction. In terms of energy, that heat represents a subtractor of the movement.

So, the mechanical energy, which is kinetic and potenial, it's transforming to "thermal energy", making the pendulum to slow down, until stops.

Now, in a perfect environment (which doesn't exist), the pendulum would never stop, and there weren'n any heat, because there wouldn't be friction. But that's not the case here.

Therefore, the best answer is A.

PLS HELP BEING TIMED!!!
Elodia [21]

Answer:

K_{i}+U_{g,i} = K_{f}+U_{g,f}

Explanation:

A closed system is a system where exists energy interactions with surroundings, but not mass interactions. If we neglect any energy interactions from boundary work, heat, electricity, magnetism and nuclear phenomena and assume that process occurs at steady state and all effects from non-conservative forces can be neglected, then the equation of energy conservation is reduce to this form:

\Delta K +\Delta U_{g} = 0 (1)

Where:

\Delta K - Change in kinetic energy of the system, measured in joules.

\Delta U_{g} - Change in gravitational potential energy of the system, measured in joules.

If we know that \Delta K=K_{i}-K_{f} and \Delta U_{g} = U_{g,i}-U_{g,f}, then we get the following equation:

K_{i}+U_{g,i} = K_{f}+U_{g,f} (2)

Where i and f stands for initial and final states of each energy component.

Hence, the right answer is K_{i}+U_{g,i} = K_{f}+U_{g,f}

Which of the following is not a component of a normal experiment?
MaRussiya [10]

Answer:

D. Validity group

Explanation:

A validity group is not necessarily a component of a normal experiment.

A normal experiment is made up of the dependent variables, independent variables, and most times the control group.

  • The dependent variable is one that relies on the outcome of the effect produced from the experimental design
  • The independent variable is the one that causes a desired effect under the study.
  • The control group is a group that does not receive any treatment nor attenuation of the conditions.
