Answer:
The magnitude of the electric field between the membranes is 1.13 x 10⁶ N/C
Explanation:
Given;
the distance of separation of the parallel plate capacitor, d = 10nm
the charge density, σ = 10⁻⁵C/m²
the magnitude of the electric field between the membranes, is calculated using the formula below;
E = σ / ε₀
Where;
ε₀ is permittivity of free space, = 8.85 x 10⁻¹² C²/Nm²
E is magnitude of the electric field between the membranes
σ is surface charge density
E = (10⁻⁵) / (8.85 x 10⁻¹²)
E = 1.13 x 10⁶ N/C
Therefore, the magnitude of the electric field between the membranes is 1.13 x 10⁶ N/C
Answer:
2.05 radians/s
Explanation:
This is a simple harmonic motion. The angular frequency of a loaded spring is given by
where 
is the spring constant and 
is the mass on the spring.
Using the known values,
Answer:
In this case we are dealing with the pythagorean theorm involving right angled triangles. This theorm states that a^2 + b^2 = c^2 which means the square of the hypotenuse (side c, opposite the right angle) is equal to the square of the remaining two sides.
In this case we will say that a = 3963 miles which is the radius of the earth. c is equal to the radius of the earth plus the additional altitude of the space station which is 250 miles; therefore, c = 4213 miles. We must now solve for the value b which is equal to how far an astronaut can see to the horizon.
(3963)^2 + b^2 = (4213)^2
b^2 = 2,044,000
b = 1430 miles.
The astronaut can see 1430 miles to the horizon.

Answer:
The point straight overhead on the celestial sphere for any observer is called the zenith and is always 90 degrees from the horizon. The arc that goes through the north point on the horizon, zenith, and south point on the horizon is called the meridian.
From any location on Earth you see only half of the celestial sphere, the half above the horizon.
If you stood at the North Pole of Earth, for example, you would see the north celestial pole overhead, at your zenith. The celestial equator, 90° from the celestial poles, would lie along your horizon.
