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
To answer the question, directly substitute the value given for t to the given function of height.
h = -16t² + 60t + 6
h = (-16)(3 s)² + (60)(3) + 6 = 42
Therefore, the height of the ball after 3 seconds is 42 ft.
In my school we have recycle bins than store trash, plastic, and paper. Every Friday a group of students in with the responsibilities collect them all together around the school and yeah...
