Answer:
These are the two statements with scientific facts that explain the described phenomenon
<span>
Gravitation between two objects increases when the distance between them decreases.</span>
When the mass of an object increases, its gravitational pull also increases.
Justification:
Those two facts are represented in the Universal Law of Gravity discovered by the scientific Sir Isaac Newton (1642 to 1727) and published in his book <span>Philosophiae naturalis principia mathematica.</span>
That law is represented by the equation:
F = G × m₁ × m₂ / d²
The product of the two masses on the numerator accounts for the fact that the gravitational force is directly proportional to the product of the masses, which is that as the masses increase the attraction also increase.
The term d² (square of the distance that separates the objects) in the denominator accounts for the fact that the gravitational force is inversely proportional to the square of the distance; that is as the separation of the objects increase the gravitational force decrease.
All we have to do is subtract
sooooo
185 - 150 = 35
so the mass of the liquid is 35g
:)
:P
:D
Answer:
B) more current.
Explanation:
When two lamps are connected in series then we have
now let the two lamps are identical
so we have
now the total resistance of the lamps is given as
now the current in that case is given as
Now when lamps are connected in parallel
net resistance of two lamps is given as
so now we have
so we have
so now the current through the battery will be
So current will be more when two lamps are connected in parallel
The final answer is 51.6 microC which is answer choice b:
Work is equal to the force exerted times the distance traveled. This can be expressed using the following formula:
W = F × D
Insert any known values into the formula above:
W = (70 N) × (9 m)
Simplify the right side of the equation:
W = 630 N·m
The work done is equal to 630 J.
I hope this helps!
