The peregrine falcon is the world's fastest known bird and has been clocked diving downward toward its prey at constant vertical
2 answers:
Answer:
Time, t = 1.02 seconds
Explanation:
It is given that,
Velocity of bird, v = 97.2 m/s
If the falcon dives straight down from a height of 100 m, d = 100 m
We need to find the time this give a rabbit below to consider his next move as the falcon begins his descent. Time can be calculated as :
t = 1.02 seconds
Hence, this is the required solution.

Answer:
-13.18°C
Explanation:
To develop the problem it is necessary to consider the concepts related to the thermal conduction rate.
Its definition is given by the function
Where,
Q = The amount of heat transferred
t = time
k = Thermal conductivity constant
A = Cross-sectional area
The difference in temperature between one side of the material and the other
d= thickness of the material
The problem says that there is a loss of heat twice that of the initial state, that is
Replacing,
Solvinf for ,
Therefore the temprature at the outside windows furface when the heat lost per second doubles is -13.18°C
Answer:
(1) En to n-1 = 0.55 ev
(2) En-1 to n-2 = 0.389 ev
(3) ninitial =4
