Slot antennas are used for their ability to provide a very directional signal (transmitted) with negligible signal lobes in the direction other than that which the slot is facing.
Yes, radar can accurately detect the speed of objects traveling in the opposite direction. Radar measures the speed of objects based on the Doppler shift principle, which is independent of the direction of movement. By analyzing the frequency shift of the radar signal, both the speed and direction of the moving object can be determined.

Uhhh . . . the answer is . . . "Population?"
An attenuator is the opposite of an amplifier. An attenuator is used for reducing the power of a signal. An attenuator is able to do this without modifying the waveform of the signal.

How Memory interface with CPU indicate the direction of signal and control signals?
During rotational acceleration, the cupula moves in the opposite direction of head rotation due to inertia, causing the hair cells to bend and trigger a signal to the brain indicating movement. During deceleration, the cupula moves in the direction of head rotation, also activating the hair cells to signal changes in movement.

Loud speaker usually has two electromagnets (or a permanent magnet and an electromagnet). When an audio signal in the form of an electric signal with desired frequency is applied to both electromagnets in opposite direction at same time so that they act as magnets with same polarities facing. This makes them repel with the given frequency, thus producing sound.
When a pressure signal is applied, the valve shaft moves in the direction opposite that of the direct-acting actuator, but it follows the same operating principle. In the reverse-acting actuator, the valve shaft is pulled into the actuator by the application of a pressure control signal.
An electromagnetic wave is a signal that goes in all directions. The wave will move uniformly through its medium if the medium is uniform. A plane wave is the concept of think an electromagnetic wave only flows in one direction.
