Answer:
3 m/s
Explanation:
Speed in m/s would just be 60 m / 20 s = 3 m/s
Answer:
X ray
Explanation:
To see an object the light used must have the same or smaller wavelength than the object. The size of an atom is about m, smaller than the wavelength, therefore we'll need radiation with a shorter wavelength <em>since X-ray wavelengths are about the same size as atoms this characteristic makes it ideal to use.</em>

The answer is it's middle the nueculs
Answer:
a) t =12[s]; b) x = 348[m]
Explanation:
We can solve this problem using the following kinematics equations:
a)
where:
vf = final velocity = 12 [m/s]
vo= initial velocity = 6 [m/s]
a = acceleration = 0.5[m/s^2]
t = time [s]
Now clearing the time t, we have:
b)
We can calculate the displacement for the first 12 [s] then using the equation for the constant velocity we can calculate the other displacement for the 20[s].
The we can calculate the second displacement for the constant velocity:
x = x1 + x2
x = 108 + 240
x = 348[m]
Answer:
lentic zones because they do not move they are stagnant water examples are ponds, swap, dams.
