Alfred Wegener believed that all of the continents were originally attached! By looking at the map, you can see that Africa and South America look like they were once joined. This 'super continent' was known as Pangaea. He also found fossils that proved his point.
Hope this helps :)

Answer:</h2>
An LC circuits if formed by an inductor and a capacitor. The charge on the capacitor and the current through the inductor both vary sinusoidally with time. Also, energy is transferred between magnetic energy in the inductor and electrical energy in the capacitor. But <em>what happens with the frequency if the inductance is quadrupled? </em>that is, if initially the inductance is 
and the frecuency 
if now 
What will the frequency be? Well, we know that the frequency, inductance and capacitance are related as:
and this equals 2000Hz. If now L is quadrupled:
<em>Finally, if L is quadrupled the frequency is half the original frequency and equals 1000Hz</em>
Answer:
165.8 V/m
Explanation:
The capacitance of a long concentric cylindrical shell of length, L and inner radius, a and outer radius, b is C = 2πε₀L/㏑(b/a)
Since the charge on the cylindrical shells, Q = CV where V = the potential difference across the capacitor(which is the potential difference between the concentric cylindrical shells)
V = Q/C
V = Q ÷ 2πε₀L/㏑(b/a)
V = Q㏑(b/a)/2πε₀L
So, the potential difference per unit length V' is
V' = V/L = Q㏑(b/a)/2πε₀
Given that a = inner radius = 1.5 cm, b = outer radius = 5.6 cm and Q = 7.0 nC = 7.0 × 10⁻⁹ C and ε₀ = 8.854 × 10⁻¹² F/m substituting the values of the variables into the equation, we have
V' = Q㏑(b/a)/2πε₀
V' = 7.0 × 10⁻⁹ C㏑(5.6 cm/1.5 cm)/(2π × 8.854 × 10⁻¹² F/m)
V' = 7.0 × 10⁻⁹ C㏑(3.733)/(55.631 × 10⁻¹² F/m)
V' = 7.0 × 10⁻⁹ C × 1.3173/(55.631 × 10⁻¹² F/m)
V' = 9.2211 × 10⁻⁹ C/(55.631 × 10⁻¹² F/m)
V' = 0.16575 × 10³ V/m
V' = 165.75 V/m
V' ≅ 165.8 V/m
I have two different answers. One is what the shcool most likely wants you to think and the other is the truth.
School: The waters could become more or less salty. Warm water is less dense than cold water so it will sit on top of cold water. It would very bad for plants because not all plants can live in such saltiness conditions.
Global Warming isn't a thing. It's fake, scientist have lied about it, and it's entirely false. The salt from the ocean comes from the constant bashing of ocean waves on the rocks. "Warm water is less dense than cold water so it will sit on top of cold water." is true, but that doesn't mean the oceans will be more salty if it is warmer, that just says how dense the salt and water is. it can be warmer or colder doesn't matter.
Hope it helps please let me know.
