It’s gas because the molecules are moving quicker.
Weathering is everywhere. An example of physical weathering would be a river flowing on rocks slowly over time the rock will wear down and an example of chemical weathering is acid rain aka the rust on a car.
Answer:
"Gases and particles in Earth's atmosphere scatter sunlight in all directions. Blue light is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time."
Answer:
0.03127 fraction of a sample of this nuclide would remain after 12.5 hrs.
Explanation:
Initial mass of the isotope =![N_o](https://tex.z-dn.net/?f=N_o)
Time taken by the sample, t = 12.5 hour
Formula used :
![N=N_o\times e^{-\lambda t}\\\\\lambda =\frac{0.693}{t_{\frac{1}{2}}}](https://tex.z-dn.net/?f=N%3DN_o%5Ctimes%20e%5E%7B-%5Clambda%20t%7D%5C%5C%5C%5C%5Clambda%20%3D%5Cfrac%7B0.693%7D%7Bt_%7B%5Cfrac%7B1%7D%7B2%7D%7D%7D)
where,
= initial mass of isotope
N = mass of the parent isotope left after the time, (t)
= half life of the isotope = 2.5 hour
= rate constant
![N=N_o\times e^{-(\frac{0.693}{2.5 hours})\times 12.5 hour}](https://tex.z-dn.net/?f=N%3DN_o%5Ctimes%20e%5E%7B-%28%5Cfrac%7B0.693%7D%7B2.5%20hours%7D%29%5Ctimes%2012.5%20hour%7D)
Now put all the given values in this formula, we get
![N=N_o\times e^{-3.465}](https://tex.z-dn.net/?f=N%3DN_o%5Ctimes%20e%5E%7B-3.465%7D)
![\frac{N}{N_o}=0.03127](https://tex.z-dn.net/?f=%5Cfrac%7BN%7D%7BN_o%7D%3D0.03127)
0.03127 fraction of a sample of this nuclide would remain after 12.5 hrs.
I believe the answer to the first question is the golf ball because it requires less energy to move it so it will move faster than the bowling ball will with less energy. For the second question I could be wrong but I think the bowling ball has more kinetic energy because according to the equation KE= 0.5*m* x^{2} where KE represents the kinetic energy the m is the mass and x is the speed of the object the bowling ball will have more energy.
