Answer:
the answer will be C. 4 degrees C
Explanation:
you subtract base meters from peak meters to get 4 meters; then Multiply 6.5 by 4.
Then subtract that total from 30 degrees C
***as altitude increases, temperature decreases***
Answer:
1.275 m
Explanation:
Let the maximum height reached be h.
Here initial velocity, u = 5 m/s
Final velocity, V = 0
Use third equation of motion
V^2 = u^2 + 2 g h
0 = 25 - 2 × 9.8 × h
h = 25/19.6 = 1.275 m
Well, in some systems the atoms melt or burn or change state like from liquid to gases when they reach a certain temperature. This could decrease the energy in the system.
Hope I helped
Answer:
The period would decrease by `sqrt(2)`.
Explanation:
The angular frequency omega of an oscillating mass m due to a spring with a constant k is given by
(this is obtained by solving the differential equation 
)
If k doubles, i.e., k'=2k, then
Since the angular frequency is 
, we can say that
and so it becomes clear that the period T will decrease by sqrt(2) as stated in choice (D).
