Answer:

<h2>The velocity is 7.82 m/s</h2>

Explanation:

In this problem, we are going to solve for the velocity since what we are given as parameters are:

1. Distance covered s= 61m

2. time taken to cover the distance t= 7.8 secs

we know that the expression for velocity is given as

velocity= distance/time

We then substitute the given data into the formula to solve for velocity.

velocity= 61/7.8

velocity= 7.82 m/s

<h2>The velocity is 7.82 m/s</h2>

Research indicate that men and women of different races expectationz regarding to gender roles. Which of these statements regard
Ilia_Sergeevich [38]

Answer:

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

Explanation:

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.

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.

Doug is doing work. Without knowing exactly what he is doing, which can be said about the work he is doing?
WARRIOR [948]
<h3>Answer;</h3>

<em>Energy is transferred.</em>

<h3>Explanation;</h3>
  • Work is the force applied over a given distance, in other words work is the product of force and distance. That is; Work = force × distance.
  • Work is measured in Joules.
  • Energy on the other hand, is the ability to do work.
  • According to the principle of work-energy a change in the kinetic energy is equivalent to the net work don e by the object. Therefore, when work is being done energy is being transferred from one point to another.

If the energies sound in the device is microphone what is the energy out
Katen [24]

Answer:

Microphones are a type of transducer - a device which converts energy from one form to another. Microphones convert acoustical energy (sound waves) into electrical energy (the audio signal). Different types of microphone have different ways of converting energy but they all share one thing in common: The diaphragm.

In a lab experiment, a student is trying to apply the conservation of momentum. Two identical balls, each with a mass of 1.0 kg,
Studentka2010 [4]

Answer:

Second Trial satisfy principle of conservation of momentum

Explanation:

Given mass of ball A and ball B =\ 1.0\ Kg.

Let mass of ball A and B\ is\ m  

Final velocity of ball A\ is\ v_1

Final velocity of ball B\ is\ v_2

initial velocity of ball A\ is\ u_1

Initial velocity of ball B\ is\ u_2

Momentum after collision =mv_1+mv_2

Momentum before collision = mu_1+mu_2

Conservation of momentum in a closed system states that, moment before collision should be equal to moment after collision.

Now, mu_1+mu_2=mv_1+mv_2

Plugging each trial in this equation we get,

First Trial

mu_1+mu_2=mv_1+mv_2\\1(1)+1(-2)=1(-2)+1(-1)\\1-2=-2-1\\-1=-3

momentum before collision \neq moment after collision

Second Trial

mu_1+mu_2=mv_1+mv_2\\1(.5)+1(-1.5)=1(-.5)+1(-.5)\\.5-1.5=-.5-.5\\-1=-1

moment before collision = moment after collision

Third Trial

mu_1+mu_2=mv_1+mv_2\\1(2)+1(1)=1(1)+1(-2)\\2+1=1-2\\3=-1

momentum before collision \neq moment after collision

Fourth Trial

mu_1+mu_2=mv_1+mv_2\\1(.5)+1(-1)=1(1.5)+1(-1.5)\\.5-1=1.5-1.5\\-.5=0

momentum before collision \neq moment after collision

We can see only Trial- 2 shows the conservation of momentum in a closed system.
