Answer:
d. the translucence of the object
Explanation:
the reason is that an object has a particular color as it is translucent to certain colors; it may absorb some colors and not show them at all, or they will reflect the remaining colors, the ones we are able to see. for eg: imagine you have a red dress. you see it as red, yet it is only reflecting the red color into your eyes, and is absorbing every other color in that light's color spectrum.
41,32,23,3632 °Fahrenheit
278.15,273.15,268.15°kelvin.
To turn °c to °f, what I learned is divide by 5, multiply by 9, then add 32
To turn °c to°k is add 273.15.
<span>The maximum possible efficiency, i.e the efficiency of a Carnot engine , is give by the ratio of the absolute temperatures of hot and cold reservoir.
η_max = 1 - (T_c/T_h)
For this engine:
η_max = 1 - [ (20 +273)K/(600 + 273)K ] = 0.66 = 66%
The actual efficiency of the engine is 30%, i.e.
η = 0.3 ∙ 0.664 = 0.20 = 20 %
On the other hand thermal efficiency is defined as the ratio of work done to the amount of heat absorbed from hot reservoir:
η = W/Q_h
So the heat required from hot reservoir is:
Q_h = W/η = 1000J / 0.20 = 5000J</span>
you would die.
the core of the earth is as hot as the sun surface so you would be dead
Answer:
displacement= 30 m towards south, distance= 210m
Explanation:
Distance (scalar quantity) how much ground an object has covered.
Displacement (vector quantity) refers to how far out of place an object is it is the object's overall change in position.
Basically meaning for displacement the directions will be very key
D for Displacement
D= D1+D2
D= 120 (S) + 90 m (N)
Must be in same direction
D= 120 (S) + (-90 m) (S)
D= 30 m (S)
and for distance you are simply just adding how much distance they have covered
so d= d1+d2
d= 90m + 120m
d= 210m
