Answer: True
Explanation:
It should be noted that when refrigerant is added in vapor form to the operating refrigeration system, then the addition of the refrigerant should be to the low-pressure side of the refrigeration system.
Furthermore, when system pressures are lower than the pressure in the refrigerant tank as stated in the question, then the refrigerant can be added to both the high and low pressure sides of the system.
Therefore, the correct option is true.
Terminal speed is the maximum speed that a falling object can reach and is based on aerodynamic resistance. In a vacuum, an object falling toward a planet as a result of gravity will continue to accelerate until it hits the ground.
However, if the object is falling through an atmosphere, such as on earth, then it will accelerate up to the point that the aerodynamic resistance cancels the downward force due to gravity, and it travels at a constant maximum speed, called the terminal velocity. At this point, resistance is equal to acceleration due to gravity. At terminal velocity, the skydiver's acceleration is zero.

Answer:
Gravitational potential energy to kinetic energy to gravitational potential energy to kinetic energy to gravitational potential energy.
Explanation:
Starting at its maximum displacement the pendulum will have only gravitational potential energy, its velocity being 0m/s. When released, it will lose height, losing then gravitational potential energy as it gains speed, or kinetic energy. When the pendulum is at its lowest the gravitational potential energy will be at its minimum and the kinetic energy at its maximum (and so its speed), with value equal to the original gravitational potential energy. Then it starts gaining height again, reverting this process, gaining gravitational potential energy and losing kinetic energy until the velocity is 0m/s again, thus returning to the state of maximum gravitational potential energy (same as originally) and null kinetic energy, but on the opposite side of the oscillation. Then the pendulum comes back repeating the exact same process just descibed, until it finishes one oscillation when reaching the original point.
