Answer:

730.4 m

Explanation:

The sound waves travels with a uniform motion (=constant velocity), therefore we can calculate the distance it travels using the formula:

d=vt

where

d is the distance

v is the speed of the sound wave

t is the time taken

In this problem we have:

v = 332 m/s is the speed of sound in air

t = 2.2 s is the time elapsed

Therefore, the distance between the tower and the person is

d=(332)(2.2)=730.4 m

According to Kepler's Third Law, a solar-system planet that has an orbital radius of 4 AU would have an orbital period of about
NARA [144]

Answer:

Orbital period, T = 1.00074 years

Explanation:

It is given that,

Orbital radius of a solar system planet, r=4\ AU=1.496\times 10^{11}\ m

The orbital period of the planet can be calculated using third law of Kepler's. It is as follows :

T^2=\dfrac{4\pi^2}{GM}r^3

M is the mass of the sun

T^2=\dfrac{4\pi^2}{6.67\times 10^{-11}\times 1.989\times 10^{30}}\times (1.496\times 10^{11})^3    

T^2=\sqrt{9.96\times 10^{14}}\ s

T = 31559467.6761 s

T = 1.00074 years

So, a solar-system planet that has an orbital radius of 4 AU would have an orbital period of about 1.00074 years.

If a person chips off a piece of this block that has a mass of 26.3 g, what will the density be of the piece? What will the dens
solmaris [256]

The density of the two pieces of rock is determined from the ratio of their masses to the pore volume of the rock.

<h3>What is density?</h3>

The density of an object is the ratio of mass to volume of the object.

Density = mass/volume

Assuming a constant pore volume of the rock = V

Density for 26.3 g = 26.3/V

Density for 58.3 g = 58.3g/V

Thus, the density of the two pieces of rock is determined from the ratio of their masses to the pore volume of the rock.
