Answer:
3V
Explanation:
From the question given above, we can see clearly that the resistors are arranged in parallel connection. Hence, the same voltage will pass through the resistors i.e
Total voltage = voltage of 3 Ω = voltage of 6 Ω
From the question given above,
The total voltage = 3 V
Therefore,
Voltage of 3 Ω = total voltage
Voltage of 3 Ω = 3V
Thus, option 3 gives the correct answer to the question.
A eclipse of the sun can only occur at a new moon when the moon passes between earth and sun. If the moons shadow happens to fall upon earths surface at a time, you'll see some portion of the suns disk covered or aka eclipsed by the moon.. I hope that helps
We can study how galaxies evolve because the farther away we look, the further back in time we see.
Answer: Option D
<u>Explanation:</u>
As the galaxies are located far away from us and also as per the broad band theory, these galaxies are spreading as the time goes. So as time passes, the galaxies are moving further light years away.
So depending upon the time taken for the light waves to reach Earth from these galaxies will state the time they have evolved. So the farther or more lately the light reaches the earth surface, the further time back we can see its evolution. Thus option d is correct choice.
Answer:
3494444444.44444 J
-87077491.39453 J
Explanation:
M = Mass of Earth = 
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
R = Radius of Earth = 
h = Altitude = 
m = Mass of satellite = 629 kg
v = Velocity of spacecraft =
