The law of physics that this scenario would violate is the law of conservation of energy.
<h3>What is the law of conservation of energy?</h3>
The law of conservation of energy states that energy possessed by an object or physical body can neither be created nor destroyed but can only be transformed from one form to another.
This ultimately implies that, the energy possessed by the rock at the beginning must be equal to the energy possessed by the rock at the end in accordance with the law of conservation of energy.

The frequency of bird chirping hear by hiran will be 1.77 kHz.
<u>Explanation:</u>
As per Doppler effect, the observer will feel a decrease in the frequency of the receiving signal if the source is moving away from the observer. So the shifted frequency is obtained using the below equation:

Here , c is the speed of sound, Vs is the velocity of source with which it is moving away. f is the original frequency of source and f' is the frequency shift heard by the observer.
As here, f = 1800 Hz, Vs= 6 m/s and c = 343 m/s, then

So, the frequency of bird chirping hear by hiran will be 1.77 kHz.
Answer:
The magnitude of the Force is
and the direction is South
Explanation:
From the question we are told that
The magnetic field point due west and since East point toward the positive x -axis
then this magnetic field would be mathematically represented as

Now from the question we are told that the kinetic energy is

Now this kinetic energy can be mathematically represented as

Where m is the mass of proton which has a general value of

Now making the subject of the formula

Substituting values we have


Now from the question we are told that proton is moving upward which is in the positive z direction so the velocity of the proton would be in the positive
So the velocity would be

Now the magnetic Force can be mathematically represented as

Where q is the charge on the proton which has a general value of 
Now substituting the value


Now according to Fleming's left hand rule the direction of the magnetic force is south toward the negative Y - direction 
So the force can be denoted as
