Answer:
6.5 × 10¹⁵/ cm³
Explanation:
Thinking process:
The relation
With the expression Ef - Ei = 0.36 × 1.6 × 10⁻¹⁹
and ni = 1.5 × 10¹⁰
Temperature, T = 300 K
K = 1.38 × 10⁻²³
This generates N₀ = 1.654 × 10¹⁶ per cube
Now, there are 10¹⁶ per cubic centimeter
Hence,
Answer:
Explanation:
load = 4500lb lift height= 30 ft
time =15 s
velocity= ft/s
velocity=2 ft/s
power = force velocity
power=
power= 9000 lb ft/s
1 hp= 550 lb ft/s
power= hp
Answer:
