Distorted maps attempt a compromise, cutting the terrestrial surface along some arbitrarily chosen lines, then projecting each lobe (or gore, in case of interruptions, repeat periodically along related lines like meridians), separately with lower overall deformation. Gore boundaries are often designed to fall on less important areas, like oceans.
False it travels faster through solids than it travels through air.
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: 1500 m/sec. ( b )
Solution:
V= f (λ)
Speed = frequency. Wavelength
And frequency = 1/time period
First we will find the frequency :
Frequency = 1/time period
1/0.006 = 166.67 Hz
Using this in the equation:
Speed = frequency. Wavelength
V= f (λ)
9 × 166.67
= 1500.03 ≈ 1500
V (Speed) = 1500 m/s.

The force between two parallel wires carrying currents in the same direction is attractive. It is repulsive if the currents are in opposite directions.
