Sulfur S 1
Explanation:
Answer:
Explanation:
= Mass of ball = 0.12 kg
tex]m_{2}[/tex] = Mass of bottle = 2.4 kg
= Initial velocity of ball
= Initial velocity of bottle
= Final velocity of ball =
= Final velocity of bottle
As linear momentum is conserved
The bottle's speed is
Answer:
The question is incomplete however this kind of questions about determinate the angular speed and taking a reference of days rotating the first star.
w=0.11312 rad/s
Explanation:
The situation is about a two star the question is incomplete, miss the time rotate one star so we assume the first star rotated once in 30 days so:
Angular momentum
The inertia
The momentum must be conserved so
notice don't have to know the mass or use the density however at the end can determinate
Time can determinate the frequency so determinate angular speed of the first star
<span>The correct answer for this question is that the passing of the moon directly between the earth and the sun is a solar eclipse. Solar eclipses cause the earth to temporarily become slightly darker, and can be observed by looking through specialist glasses so as not to damage the eyes.</span>
