Which of the following actions is best understood using Einstein's concepts rather than Newtonian physics?
2 answers:
Answer:
D.The radioactive decay of an atom
Explanation:
Newtonian physics is related to particle physics in which we deal with the properties exhibit by particles like
1). Momentum conservation
2). Particle collision theory
3). Particle dynamics
So as per all above theory we can use momentum conservation and energy conservation to find the different phenomenon.
But we could not explain the decay of radioactive atom using all above theory as it is due to unstability of nucleus and it is only explained by Einstein theory of relativity.
So here correct answer would be
D.The radioactive decay of an atom

Answer:
When the volume increases or when the temperature decreases
Explanation:
The ideal gas equation states that:
where
p is the gas pressure
V is the volume
n is the number of moles of gas
R is the gas constant
T is the gas temperature
Assuming that we have a fixed amount of gas, so n is constant, we can rewrite the equation as
which means the following:
- Pressure is inversely proportional to the volume: this means that the pressure decreases when the volume increases
- Pressure is directly proportional to the temperature: this means that the pressure decreases when the temperature decreases
