Answer:
Explanation:
The artificial gravity generated by the rotating space station is the same centripetal acceleration due to the rotational motion of the station, which is given by:
Here, r is the radius and v is the tangential speed, which is given by:
Here is the angular velocity, we replace (2) in (1):
Recall that .
Solving for :
Answer:
Polarization is the attribute that a wave’s oscillations have a definite direction relative to the direction of propagation of the wave. (This is not the same type of polarization as that discussed for the separation of charges.) Waves having such a direction are said to be polarized. For an EM wave, we define the direction of polarization to be the direction parallel to the electric field. Thus we can think of the electric field arrows as showing the direction of polarization, as in Figure 2.
To examine this further, consider the transverse waves in the ropes shown in Figure 3. The oscillations in one rope are in a vertical plane and are said to be vertically polarized. Those in the other rope are in a horizontal plane and are horizontally polarized. If a vertical slit is placed on the first rope, the waves pass through. However, a vertical slit blocks the horizontally polarized waves. For EM waves, the direction of the electric field is analogous to the disturbances on the ropes.

Answer:
linear speed = 595.706 miles/hours
Explanation:
to find the linear speed of the moon (Express your answer in miles per hour)
Given
radius of the moon = 1737.1 km = 1079.4 mile (a constant value)
The mean distance of a moon from a planet is 2.82 * 10^ 5 miles
therefore, the total distance from the moon to the planet =
=1079.4 + 2.82 * 10^ 5 = 283,079.4 miles
Assuming that the orbit of the moon around the planet is circular and that
1 revolution takes 21.6 days = 21.6*22hours = 475.2 hours
(1 day is 22 hours),
therefore, the time taken for the moon to move round the planet is = 475.2 hours
then,
linear speed = Distance/time
=283,079.4 miles /475.2 hours = 595.706 miles/hours
