Answer:
The amount of heat or moisture in the air
Explanation:
Or a switch
Answer:
(a) The rate of heat transfer is <em>238.26 kW.</em>
(b) Rate of entropy generation is <em>0.063 kW/K.</em>
Explanation:
(a) Taking the heat gained by the cold water into consideration,
<em></em>
<em>Q = (0.95 kg/s)(4.18 kJ/kg.⁰C)(70-10) = 238.26 kW.</em>
(b) Entropy generation = entropy in cold water + entropy in hot water
But
∴ = (0.95)(4.18)(ln(343/283)) + (1.6)(4.19)(ln(1- (238.26/((1.6)(4.19)(358))))
= 0.7636 + (- 0.7009) = 0.0627 kW/K.
Answer:
The main factors determining population distribution are : climate, landforms, topography, soil, energy and mineral resources, accessibility like distance from sea coast, natural harbors, navigable rivers or canals, cultural factors, political boundaries, controls on migration and trade, government policies
Explanation:
A unit of measurement expressing the intensity of a sound of power of an electrical sound
Answer:
the two gliders collide, the mobile glider will transfer a bit of time to the fixed glider, which is why it comes out with a speed that is smaller than that of the bullet glider.
Explanation:
When the two gliders collide, the mobile glider will transfer a bit of time to the fixed glider, which is why it comes out with a speed that is smaller than that of the bullet glider.
Changes can occur that the gliders unite and move with a cosecant speed less than the initial one.
The whole process must be analyzed using conservation of the moment.
