The answer is cardiovascular.
Answer: d. I or II
Explanation: A traveling wave has speed that depends on characteristics of a medium. Characteristics like linear density (μ), which is defined as mass per length.
Tension or Force (
) is also related to the speed of a moving wave.
The relationship between tension and linear density and speed is ginve by the formula:

So, for the traveling waves generated on a string fixed at both ends described above, ways to increase wave speed would be:
1) Increase Tension and maintaining mass and length constant;
2) Longer string will decrease linear density, which will increase wave speed, due to their inversely proportional relationship;
Then, ways to increase the wave speed is
I. Using the same string but increasing tension
II. Using a longer string with the same μ and T.
Answer:
The capacitance of the deflecting plates is
.
Explanation:
The expression for the capacitance of the capacitor in terms of area and distance is as follows;

Here, C is the capacitance, A is the area, d is the distance and
is the absolute permittivity.
Convert the side of the square from cm to m.
s= 3.0 cm
s= 0.030 m
Calculate the area of the square.

Put s= 0.030 m.


Convert distance from mm to m.
d= 5.0 mm

Calculate the capacitance of the deflecting plates.

Put
,
and
.



Therefore, the capacitance of the deflecting plates is
.

Answer: Pressure</h2>
<u>Pressure</u> is the force
exerted by a gas, a liquid or a solid on a surface (or area)
.
Its unit according to the International System of Units is Pascal
which is equal to
and its formula is:
