hoa [83]

Answer:

Squids = 450 - 490 nm (Moderate Frequency) (Blue)

Bees = 300 - 650 nm (Lower Frequency Bands)

Frogs = 280 - 580 nm (Very Low Frequency)

Explanation:

All of the above mentioned ranges are compared to that of humans.

I'm just surprised a little bit in the imagination that how these organisms see the world through their unique eyes. On the other hands, they are evolved like this just like we do so that may not be surprising enough. SIKE

A total resistance of 3.03 Ω is to be produced by connecting an unknown resistance to a 12.18 Ω resistance. (a) What must be the

insens350 [35]

Answer:

(a) 4.0334Ω

(b)parallel

Explanation:

for resistors connected in parallel;

$\frac{1}{R_{eq} } =\frac{1}{R1}+\frac{1}{R2}$

Req =3.03Ω , R1 =12.18Ω

$\frac{1}{3.03 } =\frac{1}{12.18}+\frac{1}{R2}$

$\frac{1}{R2}=\frac{1}{3.03 }-\frac{1}{12.18}$

$\frac{1}{R2}=0.2479$

R2=1/0.2479

R2=4.0334Ω

(b)parallel connection is suitable for the desired total resistance. series connection can not be used to achieve a lower resistance as the equation for series connection is.

Req = R1+R2

AlBr3 + K2SO4 → KBr + Al2(SO4)3

STALIN [3.7K]

On the left, you have

1 Al
3 Br
2 K
1 S
4 O

while on the right, you have

1 K
1 Br
2 Al
3 S
12 O

To get a balanced equation, you'll need 6 KBr on the right, which would require 2 AlBr3 and 3 K2SO4 on the left, so you end up with

$2\,\mathrm{AlBr}_3+3\,\mathrm K_2\mathrm{SO}_4\to6\,\mathrm{KBr}+\mathrm{Al}_2(\mathrm{SO}_4)_3$
