electromagnetic waves

Magnetic field is abeam Electrons

Answer:

= - 9.37 KJ

Explanation:

In this exercise the box has a caloric energy that must be eliminated. In several stages:  

First you must go from the current temperature to zero centigrade (T = 0ºC) which is the freezing point of water, it is heat we will call it Q₁  

Second you must lose heat without changing the temperature, it is changing state, latent heat

Third, the ice temperature should be lowered from zero degrees to T = - (5 + B) = - (5 +6) = -11 ° C, we will call it Q₂  

The heat removed is the sum of these heats  

    = Q₁ + + Q₂  

Let's calculate each one. For this you have the two equations is calorimetry.  

     Q = m (-T₀)  

     Q = m L                               change of state  

Let's calculate Q1, the data that give data is the mass m = 15.0 + A = 15.0 + 6 = 21.0 g, the initial temperature T₀ = 8.0 + C = 8.0 + 8 = 16ºC until the final temperature = 0ºC  

Let's be careful because the specific heat is mixed in units, we must place the correct units so that they are simplified; this is the mass in grams, the temperature in degrees Kelvin  

    Q₁ = m (-T₀)  

    (-T₀) = (273.15-289.15) = (0-16) = -16K  

    Q₁ = 21 4,186 (-16)  

     Q₁ = -1406.5 J  

Let's calculate the latent heat  

    = ±m L  

    = -21 333  

    = -6993 J  

The negative sign was selected because heat is being lost  

Calculate Q2  

   T = -11º C  

   Q₂ = 21 4,186 (-11 -0)  

   Q₂ = -966.97 J  

The total heat is  

    = -1406.5 - 6993 - 966.97  

    = - 9366.5 J  

The negative sign indicates that the heat is giving up.  

Reduce to kJ  

= -9366.5 J (1kJ / 1000J)  

= - 9.37 KJ

The four key components of natural selection are isolation, mutation, variation, and speciation. Or are you asking for key components of the theory of natural selection? if so, 1. Variation in population 2. Some variation is heritable 3. Reproduction + survival is non-random.  4. Individuals differ in their potential rate of surviving (and also reproducing).
