earth orbits the sun once every 365.25 days. Find the average angular. speed of Earth about the sun.Answer in units of rad/s.
anzhelika [568]

Answer:

1.99\cdot 10^{-7} rad/s

Explanation:

The average angular speed of the Earth about the Sun is given by:

\omega = \frac{2 \pi}{T}

where

2 \pi rad is the total angle corresponding to one revolution of the Earth around the Sun

T is the orbital period of the Earth

The orbital period of the Earth is 365.25 d. We must convert it into seconds first:

T=365.25 d \cdot (24 h/d) \cdot (60 min/h) \cdot (60 s/min)=3.16\cdot 10^7 s

And by substituting into the equation above, we find the average angular speed:

\omega=\frac{2 \pi rad}{3.16\cdot 10^7 m/s}=1.99\cdot 10^{-7} rad/s

The Moon is about 3.8 ✕ 108 m from Earth. Traveling at the speed of light, 3.0 ✕ 108 m/s, how long does it take a laser beam to
lana66690 [7]
Hello

1) The total distance the light has to cover to go from Earth to the Moon and back is twice the distance between the Earth and the Moon:
S=2d=2\cdot 3.8 \cdot 10^8~m =7.6 \cdot 10^8~m

2) Given the relationship
v= \frac{S}{t}
where v=3\cdot10^8~m/s is the speed of light, S the total distance covered calculate at point 1), and t the time, we can find the time the light needs to go from Earth to the Moon and back again:
t= \frac{S}{v}= \frac{7.6\cdot10^8 m}{3\cdot10^8~m/s}=2.53~s

How would the pressure and temperature at 100 m below sea level affect the speed of the air molecules in your lungs compared to
Deffense [45]
Answer: Air molecule move faster
Pressure, temperature, and volume is related to each other. If you compare sea level and 100m below sea level, 100m below sea level will have more pressure. Pressure is a force caused by molecule impact, so increased pressure means faster molecule speed. More pressure can be translated into less volume which means the air volume in the lung is decreased(with same molecule count).

Eduardwww [97]

The psychoanalytic perspective is built on foundation of case studies as Sigmund Freud has base his theory with analysis of patients of which we could point out that it has built with the foundation of case studies. It is because case studies are the researches or study that is being reviewed and are being analyzed in order to determine the causes of the problem and the solutions of it.
