A submarine is 2.99 ✕ 102 m horizontally from shore and 1.00 ✕ 102 m beneath the surface of the water. A laser beam is sent from the submarine so that the beam strikes the surface of the water 2.14 ✕ 102 m from the shore. A building stands on the shore, and the laser beam hits a target at the top of the building. The goal is to find the height of the target above sea level.

a The diagram of the situation is shown on the first uploaded image

b the angle of  incidence  beam striking the water is

c  the angle of  refraction  beam striking the water is

d The angle the refracted beam make with respect to the horizontal is

e The height of the target above sea level is  

Explanation:

From the diagram we see that the angle of the beam striking the water is

According to Snell's law

Where is the refractive index of water =  1.333

            is the angle of incidence

          is the refractive index of air  = 1

            r is the angle of refraction

 Substituting values accordingly

    Making r the subject of the formula

looking at the diagram we can see that to  obtain the angle the refraction beam makes with the horizontal   by subtracting the angle refraction from 90°

                 i.e   °

From the diagram we see that the height  target above sea level can be obtained by this relation

Where h is the is the height

  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
