Answer:
13.069 g/cm^3
Explanation:
to get density, simply divide the mass by the volume. Your equation would look like this; p=562/43
'P' represents density in this equation. Never forget to add your units!
Hope this helps!

Answer: zero (0)</h2>
Explanation:
The orbit of a body around another in space, is described by six orbital elements that determine its orientation, position, size and shape.
In the specific case of the shape of the orbit, this is determined by its <u>eccentricity</u>, which varies between 0 and 1 in the case of closed orbits (circle and ellipse). When the eccentricity is 0, the shape of the orbit is circular, when this value begins to vary until approaching 1 (without reaching 1), the shape of the orbit becomes more elliptical.
In this sense, a circular orbit will have an eccentriciy of zero.
The period is 2 seconds.
A period is a time taken to make one simple harmonic motion. It can be described as time divided by how many waves do. We can write the period formula as
T = t / n
where T is period, t is time and n is the amount of simple harmonic motions.
From the question above, we know that the mass travel up and down, it means that the cycle is one simple harmonic motion.
n = 1
t = 2s
Hence
T = t / n
T = 2 / 1
T = 2 second

The correct answer is A. Seed growth
Explanation:
Experiments often involve two main variables: the independent variable and the dependent variable. In an experiment, the dependent variable is always the main factor being studied; also, this is "dependent" because it is affected by other factors. In the case presented, the dependent variable is seed growth because this is the specific phenomenon that is being analyzed. Moreover, this factor is affected by the changes in pH. On the other hand, the pH, which is the second factor is the independent variable because this is not affected by the first variable and it is manipulated on purpose.
Answer:
8 kV
Explanation:
Here is the complete question
Assume a device is designed to obtain a large potential difference by first charging a bank of capacitors connected in parallel and then activating a switch arrangement that in effect disconnects the capacitors from the charging source and from each other and reconnects them all in a series arrangement. The group of charged capacitors is then discharged in series. What is the maximum potential difference that can be obtained in this manner by using ten 500 μF capacitors and an 800−V charging source?
Solution
Since the capacitors are initially connected in parallel, the same voltage of 800 V is applied to each capacitor. The charge on each capacitor Q = CV where C = capacitance = 500 μF and V = voltage = 800 V
So, Q = CV
= 500 × 10⁻⁶ F × 800 V
= 400000 × 10⁻⁶ C
= 0.4 C
Now, when the capacitors are connected in series and the voltage disconnected, the voltage across is capacitor is gotten from Q = CV
V = Q/C
= 0.4 C/500 × 10⁻⁶ F
= 0.0008 × 10⁶ V
= 800 V
The total voltage obtained across the ten capacitors is thus V' = 10V (the voltages are summed up since the capacitors are in series)
= 10 × 800 V
= 8000 V
= 8 kV
