Mars completes one orbit around the Sun in approximately two Earth years. Mars orbits at an average distance to the Sun of about

satela [25.4K]

Answer:

about 0.8 times

Explanation: MARS is a planet named after a Roman God of War, it is the fourth planet from the sun and the Second smallest planet following Mercury.

The orbital Speed of a planet is the speed with which the planet uses to completely go round the Sun.

The orbital Speed of the Earth is 29.78kilmeters per Second.

The orbital Speed of Mar is 0.8*29.78kilometers per second/1

=23.824kilmeters per second.

A harvest mouse can detect sounds below the threshold of human hearing, as quiet as −10 dB. Suppose you are sitting in a field o

PtichkaEL [24]

Answer:

The distance from harvest mouse to the leaf is 4.74 m.

Explanation:

Given that,

Intensity = -10 dB

Distance = 1.5 m

We need to calculate the power of intensity

Using formula of power of intensity

$P=I_{0}A$

$P=I_{0}\times4\pi r^2$

Put the value into the formula

$P=1.0\times10^{-12}\times4\pi\times(1.5)^2$

$P=28.27\times10^{-12}\ W/m^2$

We need to calculate the minimum intensity level

Using formula of minimum intensity

$I=10\log_{10}(\dfrac{I}{I_{0}})$

$-10=10\log_{10}(\dfrac{I}{I_{0}})$

$\log_{10}\dfrac{I}{I_{0}}=-1$

$I=10^{-1}\times(1.0\times10^{-12})$

$I=1\times10^{-13}\ W/m$

We need to calculate the area

Using formula of intensity

$I=\dfrac{P}{A}$

$A=\dfrac{P}{I}$

Put the value into the formula

$A=\dfrac{28.27\times10^{-12}}{1\times10^{-13}}$

$A=282.7\ m^2$

We need to calculate the distance

Using formula of area

$A=4\pi r^2$

Put the value into the formula

$282.7=4\pi\times r^2$

$r^2=\dfrac{282.7}{4\pi}$

$r=\sqrt{\dfrac{282.7}{4\pi}}$

$r=4.74\ m$

Hence, The distance from harvest mouse to the leaf is 4.74 m.
