<u>Given data</u>

mass of truck (m) = 2500 Kg ,

speed of truck (v) = 75 Km/h ,

                             = 75 × (5/18) m/s  

                                <em>  (since 1Km = 1000 meters and 1hr = 3600 seconds)</em>

                             = 20.83 m/s

Determine the wavelength (λ) =?

We know that,

              wave length (λ) = h/mv

                         where, h = plank's constant, it is a physical constant

                                        = 6.626 × 10⁻³⁴ J-s

                                      m = mass of the object in kg

                                       v = velocity/speed of the object in m/s

     Now, substituting  all the values in the equation of wave length

                                       λ = 6.626 × 10⁻³⁴ /(2500 × 20.83)

                                          =  1.2723 × 10⁻³⁸ m

<em>Wave length of the truck is  1.2723 × 10⁻³⁸ m</em>

m = mass of the truck traveling = 2500 kg

v = speed of the truck traveling = 75 km/h = 75 (km/h) (1000 m/ 1 km) (1 h /3600 sec) = 20.83 m/s

h = plank's constant = 6.63 x 10⁻³⁴

λ = wavelength of truck = ?

according to de broglie's principle, wavelength of truck is given as

λ = h/(mv)

inserting the values in the above equation

λ = (6.63 x 10⁻³⁴)/((2500) (20.83))

λ = 1.3 x 10⁻³⁸ m

How much energy is needed to completely boil a 5.05g sample of water?
Keith_Richards [23]

Given what we know, we can confirm that the amount of heat energy that would be required in order to boil 5.05g of water is that of 11.4kJ of heat.

<h3>Why does it take this much energy to boil the water?</h3>

We arrive at this number by taking into account the energy needed to boil 1g of water to its vaporization point. This results in the use of 2260 J of heat energy. We then take this number and multiply it by the total grams of water being heated, in this case, 5.05g, which gives us our answer of 11.4 kJ of energy required.

Therefore, we can confirm that the amount of heat energy that would be required in order to boil 5.05g of water is that of 11.4kJ of heat.
