Multiple choice 1. which of earth's spheres contains mountains, valleys, and other landscapes? (1 point
ycow [4]
Here are the answers:
1. Geosphere (though the term lithosphere is mostly used)
2. Both ice and wind (glaciers, and really strong winds)
3. Water
4. Its inertia (the Earth is constantly "falling" towards the Sun due to its gravitational pull, but its inertia helps the Earth from maintaining its orbit.)
5. The rotating Earth
6. one year
7. The equator
8. It depends on how much of the sunlit side of the Moon faces the Earth
9. When an object in space comes between the Sun and a third object
10. D<span>ifferences in how much the Moon and the Sun pull on different parts of Earth 
11. b. False
12. a. True

Ignoring any effects of dc resistance, what is the total reactance of a 250 mH coil in series with a 4.7 microfarad capacitor at
Paha777 [63]

The total reactance of the inductor and the capacitor is 470.1 ohms.

The given parameters;

  • <em>inductance of the coil, L = 250 mH</em>
  • <em>capacitance, C = 4.7 μ</em>
  • <em>frequency of the circuit, f = 60 Hz</em>

The inductive reactance of the coil is calculated as follows;

X_l = \omega L\\\\X_l = 2\pi f L\\\\X_l = 2\pi \times 60 \times 250 \times 10^{-3}\\\\X_l = 94.26 \ ohms

The capacitive reactance of the capacitor is calculated as follows;

X_c = \frac{1}{\omega C} \\\\X_c = \frac{1}{2\pi f C} \\\\X_c = \frac{1}{2\pi \times 60 \times 4.7 \times 10^{-6}} \\\\X_c = 564.31 \ ohms

The impedance of the circuit is calculated as follows;

Z = \sqrt{(X_c - X_l)^2} \\\\Z = X_c - X_l\\\\Z = 564.31 - 94.26\\\\Z = 470.1 \ ohms

Thus, the total reactance of the inductor and the capacitor is 470.1 ohms.
