Answer:
Explained
Explanation:
Newton would resort to the classical mechanics and say that the momentum of the particle that is moving with a constant velocity will be given by: momentum = mass x velocity
this approach will highlight the particle nature and will not be relativistic.
De-Broglie will say that the momentum of the particle is related to its associated matter wave and the relation between them is given by:
where \lambda = wavelength of the matter wave associated to the particle, h = planck's constant
and
thus, this highlights the wave nature of the particle and is also relativistic.
Answer:
The value is
Explanation:
From the question we are told that
The horizontal speed is
The horizontal distance is
Generally the time taken by the hot magma in air before landing is mathematically represented as
=>
=>
Generally the initial vertical velocity of the magma when it was lunched is
Then the final velocity of the magma when it hits the ground is mathematically represented s
Here the negative sign mean that the direction of the velocity is towards the negative y -axis
So
=>
