Vector it always consists to size(magnitude) and direction
The law of conservation states that the total amount of energy of an isolated system remains constant; it is said to be conserved over time
Meerkat is incorrect but correct the answer is 15 and yes this can be explaned by Newton’s third law of motion for every action there is an equal or opposite reaction
Your welcome and have a great day. :p
Answer:
The pendulum only has potential energy.
Explanation:
A pendulum is a weight that is tied to a rope and is also suspended with a pivot and that can swing freely. Said pendulum moves at an angle of 30 degrees. Then he is released. The pendulum moves with a constant amplitude. In this way, it reaches the maximum amplitude when its angle is 30 degrees. The angles mentioned in the exercise are the extremes. At each point, the total energy is conserved. Total energy is defined as the sum of the kinetic energies plus the potential energy. The kinetic energy of the pendulum is equal to zero in the extreme positions, therefore, only the total energy is equal to the potential energy.
