Answer 2

Noise can distort analog signals making them unreliable.

What is noise?The random or unwanted signal that mixes up with the original signal is called noise. Noise is an unwanted signal that interferes with the original message signal and causes the message signal's parameters to be corrupted. The message is transformed as a result of this change in the communication process. It's most likely to be inputted at the receiver or channel.

Noise can actually bury, distort or cause interference to the analog signal carrying the intelligent information.

What is analog signal?A signal in which a characteristic grows and decreases in lockstep with the object being sent is known as analog signal. The power of the radio wave, for example, rises and falls in accordance with the loudness of the original sound in AM radio.

The purpose of a cell phone cover is to protect your phone from impact forces. It is done by absorbing the impact of force by back cover.

What is Force ?

Force is responsible for the motion of an object. it produces acceleration in the body. According to newton's second law force is mass times acceleration i.e. F =ma. Its SI unit is N which is equivalent to kg.m/s².

The case is made in such a way that, if the cell phone is dropped, the cover will absorb the kinetic energy of the falling phone by the means of deforming without transferring the impact onto the phone.

Cell phone cover is made up of rubber which can restore the forces like a spring. when u apply force to the rubber it get displaced and applied force is stored in the rubber. when cell phone drops, rubber of the cover absorbs the energy of impact. it also provides shied protection to the phone.

Hence this is how cell phone case do this.
