(1) You must find the point of equilibrium between the two forces,
<span>G * <span><span><span>MT</span><span>ms / </span></span><span>(R−x)^2 </span></span>= G * <span><span><span>ML</span><span>ms / </span></span><span>x^2
MT / (R-x)^2 = ML / x^2
So,
x = R * sqrt(ML * MT) - ML / (MT - ML)
R = is the distance between Earth and Moon.
</span></span></span>The result should be,
x = 3.83 * 10^7m
from the center of the Moon, and
R - x = 3.46*10^8 m
from the center of the Earth.
(2) As the distance from the center of the Earth is the number we found before,
d = R - x = 3.46*10^8m
The acceleration at this point is
g = G * MT / d^2
g = 3.33*10^-3 m/s^2
Answer:
When we analyze the sentence we see that this is a hypotype with the growth of plants must behave and it has a prediction included.
Therefore the correct answer is a
Explanation:
In this exercise you are asked to identify the given sentence with a specific part of the scientific method.
Among the parts of the method we have.
* Independent variable . The controlled variable in research
*Dependent variable. The magnitude measured in the experiment
* Control variable. The magnitude that is not controlled
*Experiment. It is the design of the procedure to evaluate the hypothesis
* Hypothesis. It is the assumption with which scientific work begins
* Prediction. It is a consequence of work if the mortgage is correct.
When we analyze the sentence we see that this is a hypotype with the growth of plants must behave and it has a prediction included.
Therefore the correct answer is a
Answer:
f'=5.58kHz
Explanation:
This is an example of the Doppler effect, the formula is:
Where f is the actual frequency, 
is the observed frequency, 
is the velocity of the sound waves, 
the velocity of the observer (which is negative if the observer is moving away from the source) and 
the velocity of the source (which is negative if is moving towards the observer). For this problem:
