Answer:

Same reading.

Explanation:

Assume that after the string breaks the ball falls through the liquid with constant speed. If the mass of the bucket and the liquid is 1.20 kg, and the mass of the ball is 0.150 kg,

A.) Before the string break, the total weight = weight of the can + weight of the water.

According to Archimedes' Principle which state that: “A body immersed in a liquid loses weight by an amount equal to the weight of the liquid displaced.” Archimedes principle also states that: “When a body is immersed in a liquid, an upward thrust, equal to the weight of the liquid displaced, acts on it

B.) After the string break.

The scale will have the same reading as before the string break.

A baseball pitcher loosens up his pitching arm. He tosses a 0.20-kg ball using only the rotation of his forearm, 0.28 m in lengt
aev [14]

Answer:

Moment of Inertia, I = 0.016 kgm²

Explanation:

Mass of the ball, m = 0.20 kg

Length of the pitcher's arm, l = 0.28

Radius of the circular arc, r = 0.28 m

Moment of Inertia is given by the formula:

I = mr²

I = 0.20 * 0.28²

I = 0.20 * 0.0784

I = 0.01568

I = 0.016 kgm²

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.

a ball is projected upward at time t = 0.00 s from a point on a roof 70 m above the ground. The ball rises, then falls and strik
grin007 [14]

Answer: 17.68 s

Explanation:

This problem is a good example of Vertical motion, where the main equation for this situation is:  

y=y_{o}+V_{o}t-\frac{1}{2}gt^{2} (1)  

Where:  

y=0 is the height of the ball when it hits the ground  

y_{o}=70 m is the initial height of the ball

V_{o}=82m/s is the initial velocity of the ball  

t is the time when the ball strikes the ground

g=9.8m/s^{2} is the acceleration due to gravity  

Having this clear, let's find t from (1):  

0=70m+(82m/s)t-\frac{1}{2}(9.8m/s^{2})t^{2} (2)  

Rewritting (2):

-\frac{1}{2}(9.8m/s^{2})t^{2}+(82m/s)t+70m=0 (3)  

This is a quadratic equation (also called equation of the second degree) of the form at^{2}+bt+c=0, which can be solved with the following formula:

t=\frac{-b \pm \sqrt{b^{2}-4ac}}{2a}  (4)

Where:

a=-\frac{1}{2}(9.8m/s^{2}

b=82m/s

c=70m

Substituting the known values:

t=\frac{-82 \pm \sqrt{82^{2}-4(-\frac{1}{2}(9.8)(70)}}{2a}  (5)

Solving (5) we find the positive result is:

t=17.68 s
