Answer:
100 cubic centimeters.
Explanation:
Formula: multiply the volume value by 1.
<span>In order for the results to be valid, the dependent variable can only be affected by the independent variable, so somethings need to be kept constant. The things that need to be kept constant are called controlled variables.</span>
Answer:
0.22 m
Explanation:
= Atmospheric pressure = 101325 Pa
= Pressure at the bottom = tex]2 P_{o}[/tex] = 2 (101325) = 202650 Pa
= height of the container = 7.59 m
= depth of the mercury
Pressure at the bottom = Atmospheric pressure + Pressure due to mercury + Pressure due to water
Answer:
<h2>a) positivo.</h2>
Explanation:
The question is
The work done by gravity during a projectile decline is:
a) Positive.
b) Negative.
c) Zero.
d) Depends on y-axis direction.
e) Depends on x-axis direciton.
Remember that Work is defined as the energy needed to move an object. Mathematically, it's the product between the force exerted and the displacement. That means if we don't have any displacement, then there's no work.
In this case, we are talking about the work done by the gravity force. When a projectile goes down, it's because of the gravity force, which means it can't be zero.
Specifically, the work done by gravity is positive, because when the projectile is going down, it's getting closer to the atracttive mass, which is Earth.
Therefore, the right answer is a.
I haven’t learned this in quite a while, but from what I remember it should be A! I could be wrong but hopefully this helps
