Explanation:
It is given that,
When a high-energy proton or pion traveling near the speed of light collides with a nucleus, ![d=2.5\times 10^{-15}\ m](https://tex.z-dn.net/?f=d%3D2.5%5Ctimes%2010%5E%7B-15%7D%5C%20m)
Speed of light, ![c=3\times 10^{8}\ m\s](https://tex.z-dn.net/?f=c%3D3%5Ctimes%2010%5E%7B8%7D%5C%20m%5Cs)
Let t is the time interval required for the strong interaction to occur. The speed is given by :
![c=\dfrac{d}{t}](https://tex.z-dn.net/?f=c%3D%5Cdfrac%7Bd%7D%7Bt%7D)
![t=\dfrac{d}{c}](https://tex.z-dn.net/?f=t%3D%5Cdfrac%7Bd%7D%7Bc%7D)
![t=\dfrac{2.5\times 10^{-15}\ m}{3\times 10^{8}\ m/s}](https://tex.z-dn.net/?f=t%3D%5Cdfrac%7B2.5%5Ctimes%2010%5E%7B-15%7D%5C%20m%7D%7B3%5Ctimes%2010%5E%7B8%7D%5C%20m%2Fs%7D)
![t=8.33\times 10^{-24}\ s](https://tex.z-dn.net/?f=t%3D8.33%5Ctimes%2010%5E%7B-24%7D%5C%20s)
So, the time interval required for the strong interaction to occur is
. Hence, this is the required solution.
A lab cart is loaded with different masses and moved at various constant velocities? the anser should be
1.0m/s → 4kg
The radiation dose absorbed by a person is measured using the conventional unit rad or the SI unit gray. The biological risk of exposure to radiation is measured using the conventional unit rem or the SI unit sievert.
I hope this helps!
Answer:
0.16 m
Explanation:
A rectangular gasoline tank can hold 50.0 kg of gasoline when full, and the density of gasoline is 6.8 × 10² kg/m³. We can find the volume occupied by the gasoline (volume of the tank).
50.0 kg × (1 m³/6.8 × 10² kg) = 0.074 m³
The volume of the rectangular tank is:
volume = width × length × depth
depth = volume / width × length
depth = 0.074 m³ / 0.500 m × 0.900 m
depth = 0.16 m
