You are standing in front of a pool of water and see your face in the water but when a stone is dropped into the pool you no more see your face Explain why please

• Before, the water is calm with a regular reflection surface. So, all the light rays from your face will be reflected directly to your eyes hence viewing your face clearly.

• After throwing a stone in the pool, the water distorts or disorganises due to change in volume and molecular dislocation. So, it forms an irregular reflecting surface. Hence, all light rays from the face are reflected in different directions hence you can't see your face clearly.

Explanation:

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
