If the space station is 190 m in diameter, what angular velocity would produce an "artificial gravity" of 9.80 m/s2 at the rim?
ozzi

Answer:

The angular velocity produced is 0.321 rad/s.

Explanation:

Given :

Diameter of space station , D = 190 m.

Therefore, radius , R=\dfrac{D}{2}=\dfrac{190}{2}=95\ m.

Also, acceleration , a=9.8\ m/s^2.

We know, angular velocity , \omega=\sqrt \dfrac{a}{R}.

Putting value of g and R in above equation.

We get ,

\omega=\sqrt \dfrac{9.8\ m/s^2}{95\ m}

\omega=0.321\ rad/s.

Hence, this is the required solution.

The following problem presents hypothetical values. In the diagram below, the synodic period (one lunar month) is given as 30 da
balu736 [363]

Answer:

x is approximately 95.495

Explanation:

The given information are;

One lunar month = 30 days

The measured time between the first and third quarters = 14.9 days

Therefore, the angle of rotation for 30 days = 360°

The angle of rotation for 14.9 days = 14.9×360/30 = 178.8°

Therefore, whereby 2·θ = 178.8°

θ = 178.8°/2 = 89.4°

Therefore, given that the angle at the tangent from Sun to the Moon = 90°, we have;

The angle between the line from the Sun to the Moon = 90° - 89.4° = 0.6°

From sine rule, we have;

1/(sin 0.6) = x/(sin 90°)

x = (sin 90°)/(sin 0.6°) ≈ 95.495

x = 95.495.

Large electric fields in cell membranes cause ions to move through the cell wall. The field strength in a typical membrane is 1.
jeka57 [31]

Answer:

1.6\cdot 10^{-12}N

Explanation:

The electric force on a charged particle is given by

F=qE

where

q is the charge of the particle

E is the strength of the electric field

In this problem, we have

E=1.0\cdot 10^7 N/C is the electric field strength

q=+e=+1.6\cdot 10^{-19}C is the charge of the calcium ion

Therefore, the electric force exerted on the calcium ion is

F=(1.6\cdot 10^{-19}C)(1.0\cdot 10^7 N/C)=1.6\cdot 10^{-12}N
