The concrete slab of a basement is 11 m long, 8 m wide, and 0.20 m thick. During the winter, temperatures are nominally 17°C and

mina [271]

Answer:

$\frac{dQ}{dt}= 4312 W$

Explanation:

As we know that base of the slab is given as

$A = 11 \times 8$

$A = 88 m^2$

now we know that rate of heat transfer is given as

$\frac{dQ}{dt} = \frac{kA}{x} (T_2 - T_1)$

here we know that

$k = 1.4 W/m k$

Also we have

$x =0.20$

$\frac{dQ}{dt} = \frac{1.4(88)}{0.20}(17 - 10)$

$\frac{dQ}{dt}= 4312 W$

Perhaps to confuse a predator, some tropical gyrinid beetles(whirligig beetles) are colored by optical interference that is duet

gulaghasi [49]

Answer:

The grating spacing of the beetle is $1.078*10^{-6}m$

Explanation:

The concept to solve this problem is relate to interference effect given in the Young's Slits. Here was demonstrated that the length of the side labelled \lambda is known as the path difference. The equation is given by,

$n\lambda = dsin\theta$

Where,

$\lambda$ = wavelenght of light

N = a positive integer: 1,2,3...

$\theta$ = Angle from the center of the wall to the dark spot

d= width of the slit

Replacing our values we have that for n=1,

$dsin\theta = n\lambda$

$dsin(30)=(1)(539*10^{-9})$

$d=1.078*10^{-6}m$

Therefore the grating spacing of the beetle is $1.078*10^{-6}m$
