I'm pretty sure the answer is <u>A - It combines the gas-powered engine and an electric motor into one system.</u>
Answer:
t=2s
Explanation:
The definition of power is:
And the work-energy theorem states that:
Since the movement starts from rest, we have that:
And putting all together:
Since we want the time taken:
Which for our values is:
The forces are Andrew poking the marble and then gravity pulling the marble downward
The Indian Ocean.
The rest of your options are not oceans, they are bodies of water. (e.g: lakes,rivers,gulfs)
A )
T = mB g + mB a
T + mA a - mA g sin 35° = (Mi) mA g cos 35°
------------------------------------------------------------
T = 2.7 · 9.81 + 2.7 a
T = 26.487 + 2.7 a
26.487 + 2.7 a + 2.7 a - 2.7 · 9.81 · 0.574 = 0.15 · 2.7 · 9.81 · 0.819
5.4 a + 26.487 - 15.2023 = 3.2539
5.4 a = 8.0296
a = 1.487 ≈ 1.5 m/s²
B )
T = 2,7 · 9.81 = 26.487
26.487 - 15.2035 = (Mi) · 2.7 · 9.81 · 0.819
11.2835 = (Mi) · 21.69
(Mi) = 11.2835 : 21.69 = 0.52
