Answer:
sensory adaption
Explanation:
Sensory adaption is the phenomenon where the intensity of a stimulus experienced by an organism decreases after a certain amount of exposure to the stimulus. This happens in order for us to pay attention to other stimulus.
When you are driving with the windows down and listening to music you are subjected to a lot of stimuli. Here, most of our attention needs to be on driving. So, our brain drowns all the other unneccessary stimuli like the music.
When you enter the car again where the other stimuli which were present while driving are absent, all your attention is diverted to the music. So, your're ears hurt.
Given:
The frequency of the pendulum ( f) = 0.25 Hz.
Total time (t) = 10 s
Concept: Frequency means, the number of oscillation in one second.
Time period is the required time by pendulum to complete one oscillation.
∵ In 1.0 second, number of oscillations = 0.25
∴ In 10.0 second, number of oscillations = (0.25 ×10.0) / 1.0 = 2.5
Hence, the required number of oscillation = 2.5
1) 3 miles/Hour
The speed is defined as the distance covered divided by the time taken:

where
d = 1.5 mi is the distance
t = 0.5 h is the time taken
Substituting,

2) 1.34 m/s south
Velocity, instead, is a vector, so it has both a magnitude and a direction. We have:
is the displacement in meters
is the time taken in seconds
Substituting,

And the direction of the velocity is the same as the displacement, so it is south.
The seismographs are located in Minneapolis, Detroit, and Charleston.
Explanation:
We know that kWh is a commercial unit of energy.
Also, 1 Joule = 1 watt × 1 seconds

Since ,1 h = 3600 s and 1kW = 1000 W

So, the relation is : 
1 watt is defined as the power of an appliance when the energy is transferred at a rate of 1 Joule per second.
