Answer:

20 °C

Explanation:

Ideal gas law:

PV = nRT

Rearranging:

P / T = nR / V

Since n, R, and V are constant:

P₁ / T₁ = P₂ / T₂

488.2 kPa / T = 468 kPa / 281.15 K

T = 293.29 K

T = 20.1 °C

Rounded, the temperature was 20 °C.

The rear window in a car is approximately a rectangle, 1.3 m wide and 0.30 m high. The inside rear-view mirror is 0.50 m from th
maria [59]

Answer:

Height of mirror 0.075 m

width of mirror 0.325 m  

Explanation:

given data

wide = 1.3 m

high = 0.30 m

driver’s eyes = 0.50 m

rear window = 1.50 m

solution

we take here height / width of the mirror  is

height / width   = \frac{h}{w}   .................1

and

height /width of the window is

height /width  = \frac{h_w}{w_w}   .................2

and

distance of eye / window by the mirror is

distance of eye / window = \frac{x_e}{x_w}      .................3

so here

θ = θi  = θr    ....................4

and  tanθ for vertical is

tanθ  = \frac{h}{x_e}  

tanθ  =  \frac{h_w}{(x_e + x_w)}       ....................5

so

h =   h_w \times  \frac{x_e}{(x_e + x_e)}     ....................6

put  here value and we get

h = 0.30 \times  \frac{0.50}{(0.50 + 1.50)}  

h = 0.075 m

and

when we take here tanθ for horizontal than it will be

tanθ = \frac{w}{x_e}    

tanθ = \frac{w_w}{(x_e + x_w)}       .......................7

so

w = w_w \times  \frac{x_e}{(x_e + x_w)}         ....................8

put here value and we get

w = 1.3 \times  \frac{0.50}{(0.50 + 1.50)}  

w = 0.325 m
