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.
The net force is the sum of the forces acting on an object ( chair ).
F net = F 1 + F 2
F 1 = 20 N, F 2 = - 12 N
F net = 20 N + ( - 12 N ) = 8 N
The chair will tend to move to the left.
Answer:
(a) has the highest frequency
Explanation:
E = hf...where E(is the energy of a photon);h(is the planck's constant) and f is the frequency of the photon
Whereby this formula shows us that energy of a photon is directly proportional to its frequency
So hence if the energy is high then the frequency of the photon is also high
