Answer: 5.5 m/s
Explanation:
As we are told the runner accelerates at a constant rate, we can use the following equation:
![V_{f}=V_{o} + at](https://tex.z-dn.net/?f=V_%7Bf%7D%3DV_%7Bo%7D%20%2B%20at)
Where:
is the runner's final velocity
is the runner's initial velocity
is the runner's constant acceleration
is the time it takes the runner to reach the final velocity
![V_{f}=1.9 m/s +(1.2 m/s^{2})(3 s)](https://tex.z-dn.net/?f=V_%7Bf%7D%3D1.9%20m%2Fs%20%2B%281.2%20m%2Fs%5E%7B2%7D%29%283%20s%29)
Finally:
![V_{f}=5.5 m/s](https://tex.z-dn.net/?f=V_%7Bf%7D%3D5.5%20m%2Fs)
By using an electric field, it is feasible to differentiate between these different forms of radiation.
<h3>What is a radioactive source?</h3>
A source that emits radiation like gamma, beta, and alpha rays is said to be radioactive. Using an electric field, we can discriminate between these different forms of radiation.
The field does not deflate the gamma rays, but it does deflate the alpha and beta rays, with the alpha being deflated to the field's negative portion and the beta to its positive part.
Hence, by using an electric field, it is feasible to differentiate between these different forms of radiation.

Scientists think the most likely reason is that it was heated by tidal forces from Jupiter.
<h3>What is Tidal force?</h3>
This is known as the gravitational effect that stretches an object along the line towards the center of mass of another object as a result of gradient in gravitational field from the other body.
The moon Ganymede having a magnetic field, indicating that its interior was at least partly melted and warm was however as a result of tidal forces from Jupiter which caused the heating.

A. Physical Weathering
Explanation:
Biological weathering is caused by the actions of plants and animals as they grow, nest, and burrow.
Answer:
number of quantum states = 8
Explanation:
To find the total number of allowed states you take into account the following relations:
![l=n-1\\\\m_l=-l,-(l-1),...,0,,,,(l-1),l](https://tex.z-dn.net/?f=l%3Dn-1%5C%5C%5C%5Cm_l%3D-l%2C-%28l-1%29%2C...%2C0%2C%2C%2C%2C%28l-1%29%2Cl)
in this case you have:
![n=2\\\\l=0,1\\\\m_0=0\\\\m_1=-1,0,1](https://tex.z-dn.net/?f=n%3D2%5C%5C%5C%5Cl%3D0%2C1%5C%5C%5C%5Cm_0%3D0%5C%5C%5C%5Cm_1%3D-1%2C0%2C1)
furthermore, for each n,l,ml quantum state you have two additional states due to the spin of the electrons.
then, you have (n,l,ml) = (2,0,0), (2,1,-1), (2,1,0), (2,1,1) and with the spin:
number of quantum states = 2*(1+3) = 8
