When does a pendulum have the greatest mechanical energy

Biology
1 answer:
Valentin [98]4 years ago
7 0

A swinging  pendulum has its greatest kinetic energy and least  potential energy in the vertical position in which its speed is greatest and height least.

It has its least kinetic energy and  greatest potential energy at the extremities of its swing, in which its speed is zero and its height greatest. As the pendulum moves, energy is continuously passing back and forth between the two forms.

Neglecting friction at the pivot and air resistance, the mechanical energy (sum of kinetic and potential energies) of the pendulum is constant.

Muscles and human skeleton are very much connected with each other.

<h3><u>Explanation:</u></h3>

Muscles form one of the 5 systems of our body. They consists of both the skeletal muscles as well as the smooth muscles of our body. While the smooth muscles are the part of the organs, the skeletal muscles are attached with bones either directly attached, or they are attached with the bones by means of tendons. These muscles are formed of cells called sarcomeres and they are the structures which make the bones move. Bones ars like the rods and muscles are like hydraulics. So they are collectively called as musculoskeletal system.

Skeletal system is referred to as the collection of each and every bones of our body which is roughly 206 bones, and their organization in body helping us to stand and move.

Which of these is an example of a chemical change?
lawyer [7]

The correct options are, frying an egg and burning candle.

Explanation :

Physical change : It is a change in which no new compounds are formed only changes occurs in size or state of substance. In this, there is no changes in the substance or compound.

Chemical change : It is a change in which a new compounds are formed by the chemical reaction. Changes occurs in their chemical composition and properties.

Frying an egg : It is a chemical change because a new substance is form by heating.

Burning a candle : It is chemical change because new substances are formed (carbon dioxide, water and heat) by burning.

Boiling alcohol : It is physical change because only changes in the state.

Melting and ice : It is a physical change because only changes in the state.

Making coffee : It is a physical change because no new substance is formed.

Therefore, frying an egg and burning candle are the example of chemical change.
