The period of the pendulum is 8.2 s

Explanation:

The period of a simple pendulum is given by the equation:

$T=2\pi \sqrt{\frac{L}{g}}$

where

L is the length of the pendulum

g is the acceleration of gravity

T is the period

We notice that the period of a pendulum does not depend at all on its mass, but only on its length.

For the pendulum in this problem, we have

L = 16.8 m

and

$g=9.8 m/s^2$ (acceleration of gravity)

Therefore the period of this pendulum is

$T=2\pi \sqrt{\frac{16.8}{9.8}}=8.2 s$

As the wave interacts with a wall, which kind of wave interaction is shown?

kow [346]

The answer would be a reflection. This is because, t<span>he color of an object is actually the wavelengths of the light reflected while all other wavelengths are absorbed. Color, in this case, refers to the different wavelengths of light in the </span>visible light spectrum<span>perceived by our eyes. The physical and chemical composition of matter determines which wavelength (or color) is reflected.</span>

Answer:

Explanation:

The coordinate sketch for the system is shown in the attached file below. Also, in the cartesian coordinate system, since the height is less than the length and width, we did neglect the height. Thus, we eliminate the height and converted it to a two-dimension.

Confidence intervals for the population mean μ and population proportion p _____ as the size of the sample increases.

Masja [62]

Answer:

becomes narrower

Explanation:

Confidence intervals for the population mean μ and population proportion p becomes narrower as the size of the sample increases.

As,the sample size increases,standard error decreases,so margin of error decreases and hence width of CI decreases.

Define a method pyramidVolume with double parameters baseLength, baseWidth, and pyramidHeight, that returns as a double the volu

lara31 [8.8K]

Answer:

Explanation:

Its not a good practice to write all the functions including main() in the same class.

But as you opted for this, the code goes here like this:

public class CalcPyramidVolume {

/* Your solution goes here */

static double pyramidVolume(double baseLength, double baseWidth, double pyramidHeight)

{

double Volume,baseArea;

baseArea = baseLength * baseWidth;

Volume = baseArea * pyramidHeight * 1/3;

return Volume;

}

public static void main (String [] args) {

System.out.println("Volume for 1.0, 1.0, 1.0 is: " + pyramidVolume(1.0, 1.0, 1.0));

return;

}

And there is not caveat of integer division, as you are declaring all your variables of type double.
