It is bounced back. Like echoing, it's basically the sound wave hitting the matter it can't go through and bounce back.
If we consider all energy losses due to bearing friction and aerodynamic resistance as negligible, then the energy from the maximum potential energy and the zero kinetic energy will be preserved.
Given this assumption, the energy of the pendulum at the highest point (maximum potential energy) and the lowest point (zero kinetic energy) is equal.
Therefore,the lowest point = the highest point = 573 J.
The answer is 573 J.
Answer:
option A.
Explanation:
The correct answer is option A.
Nuclear power plant are used to generate electricity. In these power plant energy is produced by fission in the nuclear reactor.
The most common fuel used for the production of energy is U-235.
Control rods are inserted in the reactor if energy requirement is less and when energy requirement is large Control rods are remove. Hence, we can say that control rod can be used to regulate the reaction in the nuclear power plant.

Every cell has chromosomes in its nucleus. In a human cell,
there are 26 of them. AND ... lined up on every chromosome
are thousands and thousands of GENES. Those carry the
instructions for what kind of organ or bone or tissue or hair
this cell will be used to build, how the structure will work, how
tall you will be, what color your eyes will be, how deep your
voice will be, and what illnesses you will have.
Every cell has the complete set of instructions in it. In the past
several years, we have just started to be able to read them, and
extraordinary progress has been made. There's an awful long way
still left to go.
