Answer:0,002 = 2 x 10⁻³
Explanation:
0,002 = 2 / 1000 = 2 / 10³ = 2 x 10⁻³
Answer:
0
Explanation:
the momentum will always be 0 when it is at rest because the object isnt moving!

Answer: Uses of clay are as follows.
Explanation:
Clay is a type of soil whose sediment consists of particles smaller than slit, that is, around 0.004 mm. This means that particles of a clay are very small.

Answer:
The recoil speed is 
Solution:
Wavelength of a blue-green photon, 
Now, the energy associated with the blue-green photon:
where
h = Planck's constant
C = speed of light ion vacuum
Also, we know that the recoil speed can be calculated by the KInetic energy which is equal to the Energy of the blue-green photon:
where
= velocity of Hydrogen atom
= mass of H-atom
Now,
