Express the mathematical formula to calculate the number of images formed when two mirrors are inclined at θ angle.
LiRa [457]

Answer:

The number of images formed by two adjacent plane mirrors depends on the angle between the mirror. If (in degrees) is angle between the plane mirrors then number of images are given by, n = 360 θ − 1.

How does jet stream form
barxatty [35]
Even though the wind "tries" to flow from high pressure to low pressure, the turning of the Earth causes the air flow to turn to the right (in the Northern Hemisphere), so the jet stream flows around the air masses, rather than directly from one to the other.

What is the average density of a neutron star that has the same mass as the sun but a radius of only 20.0 km?
IrinaK [193]

Answer: 5.935(10)^{13}g/cm^{3}}

Explanation:

Density is a characteristic property bodies and materials, and is defined as the relationship between the mass m and the volume V, as shown below:

D=\frac{m}{V}  (1)

In the case of the neutron star, we know it has the same mass as the Sun:

m=1.989(10)^{30}kg

And its radius is r=20km

On the other hand, if we assume this neutron star has a spherical shape, its volume  can be calculated by the following formula:

V=V_{sphere}=\frac{4}{3}\pir^{3}   (2)

V=\frac{4}{3}\pi(20km)^{3}   (3)

V=33510.321km^{3}   (4)

Substituting (4) in (1):

D=\frac{1.989(10)^{30}kg}{33510.321km^{3}}  (5)

Finally:

D=5.935(10)^{25}kg/km^{3}}=5.935(10)^{13}g/cm^{3}}
