The same volume of aluminum has a smaller mass than iron and aircrafts better be light.
Answer:
Nope.
Explanation:
No. The Moon rotates on its own axis at the same rate that it orbits around Earth. That means we always see the same side of the Moon from our position on Earth. The side we don't see gets just as much light, so a more accurate name for that part of the Moon is the "far side."
Answer:
Required radius of the plates = 9.52 m
Explanation:
C = (Aε₀)/d
C = 1.8 × 10⁻⁶ F
A = ?
ε₀ = 8.8542 × 10⁻¹² F/m
d = 1.4 mm = 1.4 × 10⁻³ m
A = Cd/ε₀ = (1.8 × 10⁻⁶)(1.4 × 10⁻³)/(8.8542 × 10⁻¹²) = 281.61 m²
Area of the plate = πr² = 281.61
r² = 281.61/π = 90.59
r = √(90.59) = 9.52 m
