Answer:
Explanation:
For a linear elastic material Young's modulus is a constant that is given by:
Here, F is the force exerted on an object under tensio, A is the area of the cross-section perpendicular to the applied force, 
is the amount by which the length of the object changes and 
is the original length of the object. In this case the force is the weight of the mass:
Replacing the given values in Young's modulus formula:
They communicate their result to the scientific community- so to speak
Physical and chemical changes are similar because matter experiences a change in state while undergoing either change.
Adding an intermediate switch is not an attractive choice to span the distance between two switches due to expense issues. It may have different ports.
<h3>What is a network switch?</h3>
A switch refers to a hardware tool capable of connecting different computer devices in a network.
A network switch can connect devices on a network by centralizing communications among many devices in a given local area network.
A switch may support different speeds for transmission of data (for example, one gigabit Gbps per second).

Answer:
When one object is rubbed against another, static electricity can be created. This is because the rubbing creates a negative charge that is carried by electrons. The electrons can build up to produce static electricity. For example, when you shuffle your feet across a carpet, you are creating many surface contacts between your feet and the carpet, allowing electrons to transfer to you, thereby building up a static charge on your skin. When you touch another person or an object, you can suddenly discharge the static as an electrical shock.
Explanation:
Similarly, when you rub a balloon on your head it causes opposite static charges to build up both on your hair and the balloon. Consequently, when you pull the balloon slowly away from your head, you can see these two opposite static charges attracting one another and making your hair stand up.
