Weather meaning of physics​

Physics
1 answer:
Nostrana [21]3 years ago
8 0

Answer:

1. The day-to-day conditions of the atmosphere at a place with respect to elements like humidity, temperature, wind speed, rainfall, etc. is called the weather of that place.

2. Weather can be cloudy, sunny, rainy, stormy or clear. It is a part of the natural phenomenon which maintains the equilibrium in the atmosphere.

3. But conditions can be worse sometimes. When the atmospheric conditions are extreme or intense enough to cause property loss or life loss, such weather is termed as severe weather.

4. These also vary according to the altitudes, latitudes, and region and pressure differences. Tornadoes, cyclones, heavy rainfall, fog, winter storms come under this category. They are disastrous and hazardous. Proper disaster management and strategies are required to handle these conditions.

What are the spiral arms of the milky way made of?
valentinak56 [21]
In short, those arms are made of "stars, dust and gas". They are visible as spiral arms because they have a higher density of those objects than the space between them.
 
The arms are an area where the density of stars (and planets and other objects) is unusually high and where the start are young - recently formed- and this also gives those starts their visibility as young starts are also very bright.

A radar for tracking aircraft broadcasts a 12 GHz microwave beam from a 2.0-m-diameter circular radar antenna. From a wave persp
lubasha [3.4K]

Answer:

a) 915 m

b) 0.15 W/m^{2}

Explanation:

solution:

a) The wavelength of the microwaves electromagnetic wave is:

λ=\frac{c}{f}=\frac{3*10^{8} }{12*10^{9}}=0.025 m

the circular radar antenna acts like a circular aperture of diameter D will have a bright central maximum of diameter:

w=2.44λL/D

so at 30 km screen:

w=2.44λL/w

  =2.44*0.025*30*10^3/2

  =915 m

b)

The area of a beam at 30 km is:

A=\pi  r^{2}=\pi (\frac{w}{2} )^2=\pi (\frac{915}{2} )^2=657*10^{3} m^{2}

the average microwave intensity is equal to the ratio of the power of the antenna and area of the beam:

I=P/A

So at 30 km:

I=100*10^3/657*10^3

=0.15 W/m^{2}
