A radioactive nucleus has a half-life of 5 x 108 years. Assuming that a sample of rock (say, in an asteroid) solidified right af
1 answer:
Answer:
So the present mass will be 0.0017002 times of the initial mass of the sample.
Explanation:
Given:
- half life of the given sample,
- We know that solar system came in to existence approximately
years ago.
<u>Let the initial quantity on the formation of the solar system be, </u><u />
Then the final quantity at present be:
So the present mass will be 0.0017002 times of the initial mass of the sample.

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
