Answer:
3.045 x 10^5 Joule per second
Explanation:
A = 1 m^2
T = 1250 degree C = 1250 + 273 = 1523 K
To = 34 degree C = 34 + 273 = 307 K
e = 1
Stefan's constant, σ = 5.67 x 10^-8 watt per meter squared per kelvin to the fourth
Use of Stefan's Boltzmann law
Energy radiated per unit time
E = σ A e (T^4 - To^4)
E = 5.67 x 10^-8 x 1 x 1 (1523^4 - 307^4)
E = 3.045 x 10^5 Joule per second
Answer:
Ventricular systole
Explanation:
This contraction causes an increase in pressure inside the ventricles, being the highest during the entire cardiac cycle. The ejection of blood contained in them takes place. Therefore, blood is prevented from returning to the atria by increasing pressure, which closes the bicuspid and tricuspid valves.
Answer:
Fahrenheit is the smallest unit measuring temperature.
