<span>If the thermostat gets too hot, it will turn off the heat an turn on the air conditioner. If a thermostat gets too cool it will turn on the heat or turn off the cold air. The human body is similar to a thermostat because if people get cold, they get covered in goosebumps, if they get too hot they begin to sweat.</span>
Spurs are probably the result of <u>self-sustaining</u> <u>star formation.</u>
<h3>What is the formation of gaseous spurs in spiral galaxies?</h3>
The gigantic form of the magnificent doppelganger spiral patterns that spiral outward from the galactic cores gave spiral galaxies their name. These light arms of spiral galaxies are frequently seen in optical pictures to be speckled with bright star-forming areas at regular intervals.
Smaller structures spread forth and rearward into the interarm area from each major spiral arm. Spiral-arm also known as spurs are the name given to these substructures. Sometimes the spurs are also filled with star-forming clusters. As a consequence, we may draw the conclusion that spurs most likely emerge from self-sustaining star formation.

Answers:
1) 
2) 
Explanation:
1) Acceleration 
is defined as the variation of Velocity 
in time 
:
(1)
A body also has acceleration when it changes its direction.
In this case we have a bus with a velocity of 60m/s to the east, that accelerates in a time 10s. So, we have to find the bus's acceleration:
(2)
(3) This is the bus's accelerration
2) Now we have a car that accelerates 
to the west in order to reach a speed of 
in the same direction, and we have to find the time it takes to the car to reach that velocity.
Therefore we have to find from (1):
(4)
(5)
Finally:

Answer:
v = 1.28 m/s
Explanation:
Given that,
Maximum compression of the spring, 
Spring constant, k = 800 N/m
Mass of the block, m = 0.2 kg
To find,
The velocity of the block when it first reaches a height of 0.1 m above the ground on the ramp.
Solution,
When the block is bounced back up the ramp, the total energy of the system remains conserved. Let v is the velocity of the block such that,
Initial energy = Final energy
Substituting all the values in above equation,
v = 1.28 m/s
Therefore the velocity of block when it first reaches a height of 0.1 m above the ground on the ramp is 1.28 m/s.
Answer:
0.8 meters.
I just answered this ame question myself on a test I was taking.
