When you add up (20N down) and (10N up),
you get a sum of (10N down).
The mass of the object has no effect on the forces.
Now ... I see 5 points for the answer.
Where are the other 25 coming from ?
Choice-a is a very rubbery, imprecise, ambiguous, slippery statement. But it's probably less wrong than any of the other choices on the list.
The ocean's water's density increases when it gets colder.
The molecules in the water get colder and move less, causing it to densify... As though it were freezing (though we all know the ocean hasn't ever frozen)
Answer:
Option C is the correct answer.
Explanation:
By Charles's law we have
V ∝ T
That is
Here given that
V₁ = 0.20 cubic meter
T₁ = 333 K
T₂ = 533 K
Substituting
New volume of the gas = 0.3198 m³
Option C is the correct answer.
Answer:
B
Explanation:
It absorbs gases, but also heat energy from the atmosphere, distributes them in its depths and thus slows down changes in the entire Earth system. The amount of energy absorbed by the ocean is therefore also an indication of the total heat absorbed by the planet.
