Scorpion4ik [409]

Answer:V₁=300ml

T₁=27°C

V₂=?

T₂= -3°C

as we know

V₁T₁=V₂T₂

By putting values in formula

300ml×27°C=V₂×(-3°C)

300ml×27°C/-3°C=V₂

8100ml/-3=V₂

-2700ml=V₂

or V₂= -2700ml

Unpolarized light, with an intensity of I0, is incident on an ideal polarizer. A second ideal polarizer is immediately behind th

user100 [1]

Answer:

The light transmitted through the system will be 0.125*I₀.

Explanation:

The light transmitted through the system can be found using Malus Law:

$I = I_{0}cos^{2}(\theta)$ (1)

Where:

I: is the intensity of the light transmitted

I₀: is the initial intensity

θ is the angle relative to the first polarizer’s = 60°

Because the light transmitted by the first polarizer is dropped by half, the equation (1) results as:

$I = \frac{I_{0}}{2}cos^{2}(\theta)$

$I = \frac{I_{0}}{2}cos^{2}(60)$

$I = 0.125I_{0} = \frac{1}{8}I_{0}$

Therefore, the light transmitted through the system will be 0.125*I₀.

I hope it helps you!

Brewed coffee is often too hot to drink right away. You can cool it with an ice cube, but this dilutes it. Or you can buy a devi

RUDIKE [14]

Answer:

75.2° C

Explanation:

Given:

mass of the coffee, M = 500

mass of the cup, m = 240

since the coffee is mostly water ,

specific heat of the coffee, C = 4.184 J/kg.°C

specific heat of the aluminium, C' = 0.902 J/kg.°C

The heat lost by the coffee will be transferred to the aluminium cup. The process of heat transfer will continue till the temperature of the coffee and the cup will be in equilibrium (or same)

i.e

Heat lost by the coffee = heat gained by the cup

MC(85 - T) = mC'(T - (-20))

where, T is the temperature at the equilibrium or the final temperature

on substituting the values, we get

500 × 4.184 × (85 - T) = 240 × 0.902 × (T - (-20))

T = 75.2° C

Hence, the final temperature of the coffee will be 75.2° C
