If a 80kg diver jumps off of a 5 m high dive into a regulation diving pool, how much should the temperature of the pool go up?

Physics

Agata [3.3K]3 years ago

Answer:

The answer cannot be determined.

Explanation:

The energy of the diver when he hits the pool will be equal to its potential energy mgh, and for the temperature of the pool to rise up, this energy has to be converted into the heat energy of the pool.

The change in temperature {\Delta}T then will be

{\Delta}T=\frac{{\Delta}Q}{mc} .

Where m is the mass of water in the pool, c is the specific heat capacity of water, and {\Delta}Q is the added heat which in this case is the energy of the diver.

Since we do not know the mass of the water in the pool, we cannot make this calculation.

olchik [2.2K]

Answer:

The force required is equal to 30\pi N.

Explanation:

We know that

     Torque = force × perpendicular distance

                  = F × R = I×\alpha

               I = M×\frac{R^{2} }{2}

  From above equation \alpha  = \frac{FR}{I}              .............. 1

      We know that

              w=w_{o} +\alpha t                      ...........................2

               Given that t= 2 sec

                                  w_{o} = 0

                                  w=0.4 rev/s = 0.8\pi rad/s

From equation 1 and 2 , we get

                  F =  \frac{wI}{RT}  =  \frac{w\times m \times r}{2t}

    Upon substituting the above values we will be getting

          F = 30\pi N

If the magnetic field of an electromagnetic wave is in the +x-direction and the electric field of the wave is in the +y directio
alexandr1967 [171]

Answer:

Explanation:

The direction of propagation of electromagnetic wave

is given by the direction of vector E x B where E is electrical field , B is magnetic field .

Given Electric field  = E i because it is along x axis

Magnetic field = Bj because it is along y axis

E x B = Ei x Bj

= EB k .

so direction of E  x B is along k direction or z  - axis so wave is propagating along z - axis .
