Explanation:
From the question we are told that
The weight of the block is
The dimension of the block is
Generally two atmosphere is equivalent to
Generally 1 atm =
The area of the block would be evaluated using width and height because we need for the smaller surface to be in contact with the ground in order to maximize the pressure and minimize number of blocks
So
=>
Generally the force due to this blocks is mathematically represented as
Here N is the number of blocks
So
=>
Answer:
True
Explanation:
Matter can be in the form of a particle or a wave. This is known as the dual nature of matter. This concept was proposed by Louis de Broglie and was named after him. This phenomenon has been observed for all the elementary particles.
The de Broglie wavelength is given by
Where
h = Planck's constant
p = Particles momentum
m = Mass of particle
v = Velocity of particle
