The oak Tree would catch fire because the temperature of the blast(7200 K) is higher than the flammability limit (650 K) of the oak tree and secondly the thickness is very small
Explanation:
From the question we are told that
The temperature is
The diameter of the ball is
Hence the radius =
The total energy radiated can be mathematically represented as
Where is the Stefan-Boltzmann constant
A is the area of a sphere =
Substituting values we have
Now the state of the energy is mathematically represented as
A sketch illustrating the b part of the question is shown on the first uploaded image
looking at the height at which the blast occurs(16km) as compared to the height of the wall we notice that the height of the wall is negligibly small
from the diagram x can be calculated as follows
This value of x represents the radius of the blast(assuming it is spherical ) when it is at that wall
Now the irradiation G is mathematically represented as
Here r = 43.0813 Km = 43.0813 × 1000 = 43081.3 m
Generally the amount of energy absorbed can be mathematically represented as
Where t is the time taken
Therefore
Answer:
Explanation:
a) Show how two 2-to-1 multiplexers (with no added gates) could be connected to form a 3-to-1 MUX. Input selection should be as follows: If AB = 00, select I0 If AB = 01, select I1 If AB = 1− (B is a don’t-care), select I2
We are to show how Two-2-to -1 multiplexers could be connected to form 3-to-1 MUX
If AB = 00 select
If AB = 01 select
If AB = 1_(B is don't care), select
However, the truth table is attached and shown in the first file below.
Also, the free- body diagram for 2- to - 1 MUX is shown in the second diagram attached below.
b) We are show how two 4-to-1 and one 2-to-1 multiplexers could be connected to form an 8-to-1 MUX with three control inputs.
The perfect illustration showing how they are connected in displayed in the third free-body diagram attached below.
Where ; are the inputs of the multiplexer and Z is the output.
c) Show how four 2-to-1 and one 4-to-1 multiplexers could be connected to form an 8-to-1 MUX with three control inputs.
For four 2-to-1 and one 4-to-1 multiplexers could be connected to form an 8-to-1 MUX with three control inputs, we have a perfect illustration of the diagram in the last( which is the fourth) diagram attached below.
Where ; are the inputs of the multiplexer and Z is the output
