how do the early efforts of women during the suffrage movement compare to the later years
The idea that women's liberation is also men's liberation arouses the awakening of feminism. In 1966 Frieden and other feminists founded the National Organization for Women. Then other women's organizations for equal rights were formed in the United States and Western Europe. These organizations sought to overturn discriminatory laws and practices that forced women to hold down their status, such as discrimination in matters of contract and property ownership, employment and wages, the treatment of wage income, and issues relating to sex and child-bearing. The growing feminist movement more broadly seeks to change social stereotypes that women are more vulnerable, passive and dependent, less rational and emotionally reactive than men. Feminism strives for greater freedom for women in the workplace and makes them financially and psychologically independent of men, if they wish. Feminists criticized society's general emphasis on women as objects of sexual desire and sought to raise women's awareness and expand their opportunities in order to achieve equality with men. Another objective of feminism is to promote women's participation in all areas of political decision-making and social life.
A ball is thrown upward with a speed of 40 m/s. Approximately how much time does it take the ball to travel from the release location (A). Till its highest point (B)? Approximately how much total time is the ball in the air before it returns back to its original height (C)?
I'm going to assume that this gripping drama takes place on planet Earth, where the acceleration of gravity is 9.8 m/s². The solutions would be completely different if the same scenario were to play out in other places.
A ball is thrown upward with a speed of 40 m/s. Gravity decreases its upward speed (increases its downward speed) by 9.8 m/s every second.
So, the ball reaches its highest point after (40 m/s)/(9.8 m/s²) = 4.08 seconds. At that point, it runs out of upward gas, and begins falling.
Just like so many other aspects of life, the downward fall is an exact "mirror image" of the upward trip. After another 4.08 seconds, the ball has returned to the height of the hand which flung it. In total, the ball is in the air for 8.16 seconds up and down.

How do the individual forces compare when the rider experiences a normal
sensation of weight? What is the acceleration value when this occurs?
Answer:
The rider experiences weight or does not experience weight depends upon the direction of the elevator in which it moves and its acceleration.
Explanation:
Consider the mass of a rider as m. So its actual weight is mg and it acts vertically downward. The apparent weight of the rider is depended on the acceleration of the elevator and its direction of movement.
When elevator moves with a constant speed i.e. its acceleration is zero, the apparent weight of the rider is equal to the actual weight. Thus the rider's sensation is normal.
If the elevator is moving upward with an acceleration a, then the apparent weight of the rider will be more and the rider will experience an increase in weight or the sensation is heavy.
Or when the elevator moves downward with an acceleration a, the apparent weight of the rider is less. And the rider sensation is lighter.
The acceleration will become "0 (zero)". A further solution to the question is provided below.
Individual pressures neutralize or negate each other out if somehow the riding experiences stable weight, implying that perhaps the rider's cumulative acceleration will be zero,Now,
→ [tex]mg= W+F[/tex]
or,
→ [tex]g= a+g[/tex]
then,
→ [tex]a =0[/tex]
This means that the rider isn't moving. Thus the response above is appropriate.

A ship's propeller of diameter 3 m makes 10.6 revolutions in 30s. What is the angular velocity of the propeller?
Answer:
The angular velocity of the propeller is 2.22 rad/s.
Explanation:
The angular velocity (ω) of the propeller is:
[tex] \omega = \frac{\Delta \theta}{\Delta t} [/tex]
Where:
θ: is the angular displacement = 10.6 revolutions
t: is the time = 30 s
[tex] \omega = \frac{\Delta \theta}{\Delta t} = \frac{10.6 rev*\frac{2\pi rad}{1 rev}}{30 s} = 2.22 rad/s [/tex]
Therefore, the angular velocity of the propeller is 2.22 rad/s.
I hope it helps you!
Given:
Angular displacement,
[tex]\Theta = 10.6[/tex]Diameter,
3 mTime,
[tex]\Delta t = 30 \ s[/tex]Now,
The angular velocity will be:
→ [tex]\omega = \frac{\Delta \Theta}{\Delta t}[/tex]
By putting the values, we get
[tex]= \frac{10.6\times \frac{2 \pi rad}{1 \ rev} }{30 \ s}[/tex]

In the human circulatory system, arteries carry blood away from the heart to different parts of the body. Veins carry blood from different parts of the body back to the heart. A scientist claims that the greater the amount of exercise a person performs, the greater the amount of oxygen (O2) the body uses. He records the oxygen concentration in the blood of people while they are riding an exercise bike. The graphs show the results of this investigation.
a. Identify at least two systems within the human body that work together during exercise.
b. Explain how the evidence from the data in the graphs supports or does not support the scientist’s claim.
Answer:
There are many different systems involved in when we exercise, the three main ones are the Respiratory system which is involved in breathing the circulatory system which is about circulation of blood around the body and finally the muscular system and finally the Muscular system which is about how we move.
Explanation:
If the data consistently do not support the hypothesis, then CLEARLY, the hypothesis is NOT a reasonable explanation of what you are investigating. The hypothesis is rejected, and we search for a new interpretation, an new hypothesis that supports the experimental data
Respiratory and circulatory systems are the two systems within the human body that work together during exercise.
How does the respiratory and circulatory systems work together during exercise?The respiratory system:
allows the exchange of gases intake of oxygen and exhalation of carbon-dioxide.oxygenation of blood at the lungs.The circulatory system:

Amy crashed her bike into the fence. She was thrown over it onto the lawn. Which Newton law applies
Answer:
Newton's First Law of Motion applies here.
Explanation:
Before crashing into the fence, Amy was moving at a certain speed on her bike. As, she crashed her bike into the fence, the collision stopped the bike suddenly. But, Amy had the same speed due to inertia of her body. Due tot his speed Amy did not stop and she was thrown over the fence onto the lawn. So, the force of inertia of Amy's body caused her to be overthrown in this case. We study about inertia in Newton's First Law of Motion, which is also known as Law of Inertia.

Calculate the acceleration in meters per second-squared, of a car moving at 10 m/s that accelerates to 24 m/s over a time of 7 second--
Explanation:
v = u + at
24 = 10 + a * 7
24 = 10 * 7 a
a = 24 - 10/7
a = 14/7
a = 2m/sec^2
hope it helps you
Answer:
First calculate change in velocity:
final velocity = 20 m/s.
initial velocity = 30 m/s.
change in velocity = (20 - 30) = -10 m/s.
acceleration = -10 ÷ 25.
acceleration = -0.4 m/s 2
The acceleration value is negative here because the car is slowing down or decelerating.
Explanation:
Find the range of a projectile launched at an angle of 30⁰with an initial velocity of 20m/s
Initial velocity of projection (u) = 20 m/s
Angle of projection (θ) = 30°
Formula of Horizontal Range of Projectile:
[tex] \boxed{ \bf{R = \dfrac{2u^2 sin\theta .cos \theta}{g}}}[/tex]
By substituting values in the formula, we get:
[tex] \rm \longrightarrow R = \dfrac{2 \times 20^2 \times sin30 \degree \times cos 30 \degree}{10} \\ \\ \rm \longrightarrow R = \dfrac{ \cancel{2} \times 40 \cancel{0} \times \dfrac{ \sqrt{3} }{ 2} \times \dfrac{1}{\cancel{2}} }{ \cancel{10}} \\ \\ \rm \longrightarrow R =40 \times \dfrac{ \sqrt{3} }{ 2} \\ \\ \rm \longrightarrow R =20 \sqrt{3} \: m \\ \\ \rm \longrightarrow R =34.641 \: m[/tex]

Amanda studies a waveform. She labels parts of the waveform using variables (P,Q,R, and S), as shown in the image.
Which label part represents the wavelength
Answer:
Q
Explanation:
To know which symbol defines the wavelength, we must know the definition of wavelength.
Wavelength can be defined as the distance between two successive crests (i.e the highest part) or troughs (the lowest part) of a wave.
Considering the diagram given above, Q shows the distance between two successive crests (i.e the highest part) of the wave. Therefore, Q is the wavelength of the wave given in the diagram above.
Rocket-powered sleds are used to test the human response to acceleration. If a rocket-powered sled is accelerated to a speed of 444 m/s in 1.83 seconds, then what is the acceleration?
Answer:
[tex]a=242.62\ m/s^2[/tex]
Explanation:
The rocket-powered sled is accelerated to a speed of 444 m/s in 1.83 seconds.
We need to find the acceleration of the rocket. Initially it was at rest, u = 0
Acceleration = rate of change of velocity
[tex]a=\dfrac{444\ m/s}{1.83\ s}\\\\a=242.62\ m/s^2[/tex]
So, the acceleration of the rocket is [tex]242.62\ m/s^2[/tex].
