Answer:
physical health
Explanation:
Physical health has many components including: exercise, nutrition, sleep, alcohol & drugs, and weight management.
Answer
Integral EdA = Q/εo =C*Vc(t)/εo = 3.5e-12*21/εo = 4.74 V∙m <----- A)
Vc(t) = 21(1-e^-t/RC) because an uncharged capacitor is modeled as a short.
ic(t) = (21/120)e^-t/RC -----> ic(0) = 21/120 = 0.175A <----- B)
Q(0.5ns) = CVc(0.5ns) = 2e-12*21*(1-e^-t/RC) = 30.7pC
30.7pC/εo = 3.47 V∙m <----- C)
ic(0.5ns) = 29.7ma <----- D)
Do it as if you are writing a yes or no statement but have edge more towards the no side.
Answer:
Thickness of Styrofoam insulation is 0.02741 m.
Explanation:
Given that,
Height = 0.25 m
Depth = 0.5 m
Power = 400 W
Temperature = 33°C
We need to calculate the area of Styrofoam
Using formula of area
Put the value into the formula
Inner surface temperature of freezer
Outer surface temperature of freezer
We need to calculate the thickness of Styrofoam insulation
Using Fourier law,
Put the value into the formula
Hence, Thickness of Styrofoam insulation is 0.02741 m.
