Option (A) is correct. Fission and fusion reactions both involve making changes to an atom's nuclei.
Nuclear fission is a process in which a bigger nucleus breaks into two or more smaller nuclei with the liberation of large amount of energy.
Nuclear fusion is a process in which two smaller nuclei fuse together to form a bigger nucleus. A tremendous amount of energy is released during fusion.
Thus both fission and fusion involve the changes in the nuclei of atoms. Rest of the atom like the electronic configuration etc remains same.
Answer:
Speed = 2.4 m/s
Explanation:
As given in question,
Frequency of the wave = 4 Hz
The wavelength of the wave = 60 cm
As we know,
1 cm = 0.01 m
=>60 cm = 0.6 m
So, the wavelength of the wave = 0.6 m
speed of wave = wavelength x frequency
= 0.6 m x 4 Hz
= 2.4 m/s
Hence, the velocity of wave vibrating with 4 Hz frequency and wavelength of 60 cm is 2.4 m/s.
Answer:
v_o= 12 m/s
Explanation:
The ball experienced a constant acceleration motion, so we need to apply the following formula:
Note: we set the acceleration of gravity as negative because it is going down.
the ball was thrown vertically upward with an initial velocity of 12 m/s
Answer:
False
Explanation:
it is very rare to get hyposmia
