Answer:
Explanation:
The thermal efficiency of a Power cycle
where;
--- (1)
---- (2)
The coefficient of performance is:
let replace the value of in the above equation then;
The
On the other hand, the heat pump
By replacing equation (1) into the above equation; we have:
t
'G' = "giga..." = billion = 10⁹
'ms' = "millisecond" = 0.001 second
100 Gw = 10¹¹ watts
35 ms = 0.035 second
100 Gw x 35 ms = 10¹¹ watts x 0.035 second = 3.5 x 10⁹ J
= 3.5 G-joules
Answer:
B. The force due to gravity is 530 N. The force of air resistance is less than the force due to gravity.
Explanation:
I think everytime they swim away, the water pushes the enemy back, which makes the octopus go faster. Every action has an equal and opposite reaction. Hope this helps.
