What effect does noise have on different types of signals?
A. It distorts digital signals, making them unreliable.
B. It distorts analog signals, making them unreliable.
C. Noise has no effect on either analog or digital signals.
D. Noise prevents the transmission of both analog and digital
signals.
Answers
Answer: it is actually B. :)
Explanation:
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.Hence, the correct answer is B.

A student slides a rock along the flat surface of a frozen pond. The rock starts to slow down after several seconds. Construct an explanation using Newton's Laws that describes why the rock begins to decelerate.
Answers
Answer:
When the student slides the rock along the flat surface of the frozen pond, according to Newton's second law of motion, the rock is given an initial velocity of motion. According to Newton's first law of motion, the rock will continue to slide indefinitely unless it is slowed or stopped by an opposite force. According to Newton's third law, the rock experiences a reaction force from the force of friction of the ice which slows it down at a rate given by Newton's second law of motion and the rock is seen to decelerate
Explanation:
Newton's first law of motion, states that an object will remain at rest or maintain a uniform motion in a straight line, unless impressed upon by an external force
Newton's second law states that an applied force is equal to the rate of change of momentum it produces
Newton's third law states action and reaction are equal and opposite.
The purpose of a cell phone cover is to protect your phone from impact forces. How does a cell phone case do this?
Answers
Answer:
the material of the phone case
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.
