A projectile is fired vertically from Earth's surface with
scoray [572]

Answer:

h=25.52\times10^6 m

Explanation:

Initial speed, v = 10 x 10^3 m/s

Mass of the earth, M = 6 x 10^24 kg

Radius of the earth, R = 6.4 x 10^6 m

Maximum from the surface of earth, h = ?

Let  m = Mass of the projectile

Solution:

Potential energy at maximum height =  ( Potential + Kinetic energy ) at the surface

-G M m / ( R + h )=- G M m / R + (1/2) m v^2

- G M / ( R + h ) = - G M / R + (1/2) v^2

-2\times G M / ( R + h ) = ( - 2 G M / R ) + v^2

-2\times6.67\times10^{-11}\times6\times10^{24}/ ( R + h )

=( (- 2\times 6.67\times10^{-11}\times6\times10^{24}) /(6.4\times10^6)} +10000^2

=-2.50625\times10^7 J

=- 8\times10^{14} / ( R + h )=-2.50625\times 10^7

R+h=31.92\times10^{6}

h=31.92\times10^{6}-6.4\times10^6

h=25.52\times10^6 m

Ilia_Sergeevich [38]

Answer:

Asian American women are more likely than Asian American men to value egalitarian roles for men and women.

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.

6. In general, men and women differ physically from but women have greater endurance than men.

There should be gender equality because *The Equal Pay Act of 1963" says that men and women receive equal pay for equal work.

Sexual harassment is a form of overt discrimination that has a negative impact on women's.

But today, both men and women say it is not fair for men to be the sole decision maker in the household.

Research on the impact of peer relationships on socialization have found that

1. for boys and girls peers reinforce age and racial norms as well as gender expectations.

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

3. homophobia serves to reinforce gender norms.

A mass of 0.54 kg attached to a vertical spring stretches the spring 36 cm from its original equilibrium position. The accelerat
UNO [17]
<h2>Spring constant is 14.72 N/m</h2>

Explanation:

We have for a spring

            Force =  Spring constant x Elongation

            F = kx

Here force is weight of mass

           F = W = mg = 0.54 x 9.81 = 5.3 N

Elongation, x  = 36 cm = 0.36 m

Substituting

           F = kx

           5.3 = k x 0.36

             k = 14.72 N/m

Spring constant is 14.72 N/m
