Answer:
Incident solar radiation.
Explanation:
Isolation is defined as the solar radiation that reaches surface of the earth. Isolation term is derived from the word solar radiation. It is mainly applied to radiation which is first arriving earth atmosphere, and then second arriving earth surface.
Isolation is measured by the amount of incoming solar energy received by the earth per square centimeter per minute. Isolation affects some factors such as temperature, the more the isolation cause higher the temperature.
Answer:0.853
Explanation:
Given
Reliability of A is 0.90
Reliability of B is 0.80
Reliability of C is 0.99
B has a backup with reliability of 0.8
i.e. B has a component in parallel to it.
A,B& C is series.
B actual reliability is
Thus 
is given by
Answer:
Time taken, t = 3.53 seconds
Explanation:
It is given that,
The formula for calculating the time t is given by :
...... (1)
Where
s is the distance in feets
We need to find the time taken by the stone to drop a distance of 200 feets, s = 200 feets
Put the value of s in equation (1) such that,
t = 3.53 seconds
So, the time taken by the object is 3.53 seconds. Hence, this is the required solution.
Answer:
Half life refers to the time for 1/2 of the radioactive atoms to decay.
Suppose that X has a half life of 10 days and Y has a half life of 20 days
If both start out with 1000 radioactive atoms then after 20 days
X would have 250 radioactive atoms and Y would have 500 atoms
The rate of decay is greater for the shorter half life:
In the example given X must have the smaller rate of decay because it has a longer half life.
