What linear speed must an earth satellite have to be in a circular orbit at an altitude of 159 km?
IgorLugansk [536]
Gravitational acceleration, g = GM/r^2. Additionally, for a satellite in a circular orbit, g = v^2/r

Where, G = Gravitational constant, M = Mass of earth, r = distance from the center of the earth to the satellite, v = linear speed of the satellite.

Equating the two expressions;
v^2/r = GM/r^2
v = Sqrt (GM/r);
But GM = Constant = 398600.5 km^3/sec^2
r = Altitude+Radius of the earth = 159+6371 = 6530 km

Substituting;
v = Sqrt (398600.5/6530) = 7.81 km/sec = 781 m/s

Gender biased has made the environment have different races expectation regarding to gender role.

A socialist feminine (Anita) believes that the oppression of women is based on the capitalist economy.

Parent influence an individuals on their lives socialization.

Some expectations of gender expectation.

1. Men are expected to gain more income, power, and social standing than females.

2. Using biological determinism, it shows that women are more hormonal and men are more aggressive.

3. Few percent of women are in the paid labor force while, large percent of men are in the paid labor force.

4. There is occupational segregation and this why women make up 97% of secretaries and 95% of child-care workers.

5. It is believed that women live longer than men, and this might be due to the stress the man has gone through during is life.

2. gender norms are applied more strictly to boys than to girls.

3. homophobia serves to reinforce gender norms.

Voices of swimmers at a pool travel 400 m/s through the air and 1,600 m/s underwater. The wavelength changes from 2 m in the air
frosja888 [35]

The frequency of the wave has not changed.

In fact, the frequency of a wave is given by:

f=\frac{v}{\lambda}

where v is the wave's speed and \lambda is the wavelength.

Applying the formula:

- In air, the frequency of the wave is:

f=\frac{400 m/s}{2 m}=200 Hz

- underwater, the frequency of the wave is:

f=\frac{1600 m/s}{8 m}=200 Hz

So, the frequency has not changed.
