Why cooking pans don't have have metal handles?

2 answers:

4 0

metals are conductors, meaning that heat travels through it better than insulators such as plastic (commonly used for pan handles)

Therefore, to avoid the heat burning hands, most pans don't have metal handles.

Probably because during cooking they will also be hot and you won't be able to handle it.

Some unpolarized light has an intensity of 1375 W/m2 before passing through three polarizing filters. The transmission axis of t

chubhunter [2.5K]

Answer:

intensity of the light that emerges from the three filters is 560.80 W/m²

Explanation:

Given data

intensity I = 1375 W/m2

angle 1 = 31.0°

angle 2 = 41.0°

to find out

intensity of the light that emerges from the three filters

solution

we know intensity of light pass 1st polarize = I/2 = 1375 / 2 = 687.5 W/m2

so intensity after 2nd polarize pass = I 1st cos²(θ)

I 2nd = 687.5 cos²(31) = 687.5 ( 0.836754) = 575.27 W/m2

and

intensity after 3rd polarize pass = I 2nd cos²(θ)

I 3rd = 575.27 cos²(41) = 575.27 (0.974839) = 560.80 W/m2

so that intensity of the light that emerges from the three filters is 560.80 W/m²

An apple is thrown across the cafeteria with a force of 10 N and at an acceleration of 6 m/s2. What is the mass of the apple? ..

Komok [63]

Answer:

Explanation:

F = m * a

The apple's acceleration is not influenced by the acceleration due to gravity for this question. In real life it most certainly is influenced by gravity.

F = m * a

F = 10 Newtons.

a = 6 m/s^2

m = 10/6 = 1.66 kg. Mighty large apple

Two brothers are digging a drainage ditch for a french drain around their home. The ditch is to be 2 feet deep, 1 foot wide, and

alukav5142 [94]

Answer:

The two brothers working together will take 7.7 hours to dig the entire ditch.

Explanation:

Assuming T to be the total amount of time taken by both brothers working together, we can say

1/T ditch/hour to be the rate at which both brothers dig the ditch together
1/14 ditch/hour to be the rate at which the older brother digs the ditch
1/17 ditch/hour to be the rate at which the younger brother digs the ditch

So the rate at which both brothers dig the ditch can be calculated by the equation,

1/T = 1/14 + 1/17

T = 238/31 = 7.7 (rounded off to the nearest tenth)
