Answer:

The number of molecules displaced by a vibration creates the amplitude of a sound. The strength or level of sound pressure. The number of molecules in the sound wave in b is greater than the number in the sound wave in a, therefore the amplitude of the sound wave in b is greater.

Mercury has an average disease to the sun of 0.39 AU. In two or more complete sentences, explain how to calculate the orbital pe
alukav5142 [94]

Answer: 88 Earth days

Explanation:

According to the Kepler Third  Law of Planetary motion <em>“The square of the orbital period of a planet is proportional to the cube of the semi-major axis (size) of its orbit”. </em>

<em />

In other words, this law states a relation between the orbital period T of a body (moon, planet, satellite) orbiting a greater body in space with the size a of its orbit:

T^{2}=a^{3} (1)

If we assume the orbit is circular and apply Newton's law of motion and the Universal Law of Gravity we have:

T^{2}=\frac{4\pi^{2}}{GM}a^{3} (2)

Where M is the mass of the massive object and G is the universal gravitation constant. If we assume M constant and larger enough to consider G  really small, we can write a general form of this law:

MT^{2}=a^{3} (3)

Where T is in units of Earth years,  a is in AU (<u>1 Astronomical Unit is the average distane between the Earth and the Sun)</u> and  M is the mass of the central object  in units of the mass of the Sun.

This means when we are making calculations with planets in our solar system  M=1.

Hnece, in the case of Mercury:

(1)T^{2}=(0.39 AU)^{3} (4)

Isolating T:

T=\sqrt{(0.39 AU)^{3}} (5)

T=0.243 Earth-years \frac{365 days}{1 Earth-year}=88.6 days \approx 88 days (6)

This means the period of Mercury is 88 days.

The images output from your new color laser printer seem to be a little too blue. What can you do to fix this?
Svetradugi [14.3K]

Answer:

The images output from your new color laser printer seem to be a little too blue. to fix this problem we need to calibrate the printer.

Explanation:

This can be done by opening the toolbox, clicking in the device setting folder their you get print quality page click on it. Under the print quality option click on the calibrate next to calibrate now. Then click OK unless when the 'your request has been sent to the device' appears on the screen. When the calibration ends again try printing. calibrating is useful for managing the proper alignment of the inkjet cartridge nozzle to the paper and each other, without proper calibration the print quality deteriorates.
