22.5 m/s
This is because the puck will not slow down, and maintain a constant velocity.
Answer:
We know that in the decay process the sum of molecular number as well as molecular weight should be constant.
The following three reaction are as follows
1 .
Alpha decay of parent nuclide
The molecular number of alpha particle is 2 and molecular weight is 4 g/mol.
2.
Beta decay of daughter nuclide
v is the neutrino emission,The charge on the beta particle is zero.
3.
Alpha decay
Answer:
1.52 * 10⁵ K
Explanation:
When the temperature of a blackbody radiator increases, the overall radiated energy increases and the peak of the radiation curve moves to shorter wavelengths. When the maximum is evaluated from the Planck radiation formula, the product of the peak wavelength and the temperature is found to be a constant.
By Wien's Law,
λ * T = 2.898 * 10⁻³ mK
∴ T = 2.898 * 10⁻³/λ
Given λ = 19 nm = 19 * 10⁻⁹
T = 2.898 * 10⁻³ / 19 * 10⁻⁹
=1.52 * 10⁵ K
NO. although the arrangement of the atoms will change, the total number stays constant.
