convert 40db to standard gain
AL=10^40/20=100
calculate total voltage gain
=AL×RL/RL+Ri
=83.33
38.41 DB
calculate power
Pi=Vi^2/Ri Po=Vo^2/RL
power gain= Po/Pi
=13.90×10^6

Answer:
the sun gives off light while at the same time gives off heat. the shoe box cooker takes that heat and light and reflects it around the shoe box. then the heat settles down into whatever is in the shoe box. the heat after being reflected around the shoe box is magnified by the foil wrapped in the box thus allowing the food or drink to be heated. the foil is a conductor of heat because it is metal .

Answer:
critical stress 
= 1382.67 MPa
Explanation:
given data
plane strain fracture toughness = 54.8 MP
length of surface creak = 0.5 mm
we take here
parameter Y = 1.0
solution
we apply critical stress formula that is
critical stress = 
.............................1
here K is design stress plane strain fracture toughness and a is length of surface creak so put all these value in equation 1
critical stress = 
solve it we get
critical stress = 1382.67 MPa
As exposed stress 1030 MPa is less than critical stress 1382 MPa
so that fracture will not be occur here
