1 atm corresponds to 760 mmHg, so we can set up a simple proportion to find how many atmospheres correspond to 570 mmHg:
and from this, we find
Answer:
the tension in the part of the cord attached to the textbook is 7.4989 N
Explanation:
Given the data in the question;
As illustrated in the image below;
first we determine the value of the acceleration,
along vertical direction; we use the second equation of motion;
y = ut + 
a
t²
we substitute;
0 m/s for u, 1.29 m for y, 0.850 s for t,
1.29 = 0×0.850 + ×a×(0.850)²
1.29 = 0.36125a
a = 1.29 / 0.36125
a = 3.5709 m/s²
Now when the text book is moving with acceleration , the dynamic equation will be;
T₁ = m₁a
where m₁ is the mass of the text book ( 2.10 kg )
a is the vertical acceleration ( 3.5709 m/s² )
so we substitute
T₁ = 2.10 × 3.5709
T₁ = 7.4989 N
Therefore, the tension in the part of the cord attached to the textbook is 7.4989 N
Hey there!
A sound wave is a<u> longitudinal wave</u>, meaning that the motion of the particles of the wave is parallel to the direction of the motion of the wave.
Hope this helps!
Answer: the dependent variable was the learning outcome.
Explanation:
1) The dependent variable is the variable that is explained by the indepent variable.
The dependent variable is not changed or fixed by the experiment, but it is a response from the change in the independent variable.
2) The independent variable is the variable that can be changed arbitrarily (inside the physical restrictions).
In this case, the variable that is changed at will of a part (may be the own will of the students or an imposition of the teacher, or other reason, it does not matter), is the kind of activity to learn: either learning from a video game or from traditional classroom activities).
Therefore, the independent variable is the kind of learning mode.
On the other hand, the learning outcome is the variable studied. The experiment is meant to determine how the learning outcome is related or explained by the kind of learning activity.
Therefore, the learning outcome is the dependent variable.
