Answer:
It's short, cool summers (where snow could be year round) and long cold winters.
Answer:
a)693.821N/m
b)17.5g
Explanation:
We the Period T we can find the constant k,
That is

squaring on both sides,

where,
M=hanging mass, m = spring mass,
k =spring constant
T =time period
a) So for the equation we can compare, that is,

the hanging mass M is x here, so comparing the equation we know that

b) In order to find the mass of the spring we make similar process, so comparing,

Answer:
They land at the same time.
Explanation:
Two masses falling through a vacuum (no air resistance or buoyancy forces) will accelerate at the same rate when dropped from the same height. Therefore, despite having different masses, they land at the same time.
When we breathe in air at sea level, the atmospheric pressure of about 14.7 pounds per square inch (1.04 kg. per cm.2) causes oxygen to easily pass through selectively permeable lung membranes into the blood. At high altitudes, the lower air pressure makes it more difficult for oxygen to enter our vascular systems.
hope this helps :)
