The largest watermelon ever grown had a mass of 118 kg. Suppose this watermelon were exhibited on a platform 5.00 m above the gr

ound. After the exhibition, the watermelon is allowed to slide along to the ground along a smooth ramp. How high above the ground is the watermelon at the moment its kinetic energy is 4.61 kJ?

Answer: height = 3.98m

Explanation: by placing the watermelon at a height above the ground, it has a potential energy of the formulae

p = mgh

p = potential energy = 4.61kJ = 4610J

m = mass of watermelon = 118 kg

g = acceleration due gravity = 9.8 m/s²

4610 = 118 * 9.8 * h

h = 4610/ 118 * 9.8

h = 4610/ 1156.4

h = 3.98m

A proton is accelerated to 225V. Its de-Broglie wavelength is:
marin [14]

Answer:

The  value  is  \lambda =  1.9109 *10^{-12} \  m

Explanation:

From the question we are told that

  The  potential of the proton is  V  =  225 \  V

Generally the momentum of the particle is mathematically represented as

         p  =  \sqrt{ 2 *  m  *  V  *  e }

Here  e is the charge on the proton with value  

       e =  1.60 *10^{-19} \  C

      m is the mass of the proton with value  m  =  1.67 *10^{-27} \  kg

So

    p  =  \sqrt{ 2 * (1.67*10^{-27} ) *  225 *  1.6*10^{-19}}

=>    p  = 3.4676 *10^{-22} \  kg \cdot m/ s

So the de-Broglie wavelength isis mathematically represented as

     \lambda  =  \frac{h}{p}

Here  h is the Planck's  constant with value  

       h = 6.626 *10^{-34} \  J\cdot s

=>   \lambda  =  \frac{6.626 *10^{-34}}{3.4676 *10^{-22} }

=>\lambda =  1.9109 *10^{-12} \  m
