Based on research studies, in a classic series of studies, Solomon Asch showed that an individual can conform to a group's judgment of the lengths of lines "even when the group judgment was incorrect."

What is Solomon Asch Conformity Experiment?

Solomon Asch Experiment was conducted in 1955 to study the effect of majority or groups on individual beliefs and opinions.

The study's outcomes showed that people would conform with a group, even if they believe or understand it is wrong.

Hence, in this case, it is concluded that the correct answer is "even when the group judgment was incorrect."

Two football players are running toward each other. One football player has a mass of 105 kg and is running at 8. 6 m/s. The other player has a mass of 90 kg and is running at -9. 0 m/s. What is the momentum of the system after the football players collide? 93 kg · m/s 1,713 kg · m/s. 810 kg · m/s. 903 kg · m/s.

Answers

The correct answer is P = 1740 kg · m/s, we got this answer by applying the momentum expression which is P = Δ(mv), based on the fact that the mass is not constant

Given data

Mass of Player one = 105kg

Mass of Player two = 93Kg

The Velocity of Player one = 8.6m/s

The Velocity of Player two = -9.0m/s (the negative sign indicates the opposite direction to player one)

Applying Newton’s Second Law in Terms of Momentum because the mass is not constant

When Newton’s second law is expressed in terms of momentum, it can be used for solving problems where mass varies,

We also want to assume that the players stuck together after the collision

An inelastic collision, in contrast to an elastic collision, is a collision in which kinetic energy is not conserved due to the action of internal friction.

P = M1V1 + M2V2

P= 105*8.6+93*9.0

P = 903 +837

P = 1740 kg · m/s.

Sea level is currently rising at 5 mm/yr, and scientists predict that global warming could cause a rise in sea level of 7 m if left unabated. How long will it take the sea to rise 7 m at the current rate?.

Answers

Answer:

1400 years

Explanation:

Let us convert everything to the same units first. For simplicity, I will convert everything to millimeters.

7 m = 7 m x (1000 mm / 1 m) = 7000 mm

Since the rate is 5, we can use this equation:

rate*time=length

5*years=7000

solve

years=1400

English nobles resisted peasant demands such as those described in the passage because agricultural labor in many parts of fourteenth-century afro-eurasia had become scarce as a result of which of the following developments?.

Answers

Answer: Significant increase in mortality due to the spread of epidemic diseases.

Explanation:

During the 14th century, many parts of Europe and Asia were completely ravaged by an epidemic plague called The Black Death. It was a form of bubonic plague caused by rats infected by bacteria.

More than half of the population of Europe was killed due to his plague, which immediately creates a shortage of labor. Shortage of labor, including agricultural ones, immediately meant that the living ones would receive a higher wage, to the consternation of the landowners who pushes for legislation that would return the status quo to how it was prior to the Black Death. This enrages the peasants who worked for them; manifesting in several revolts from May to November 1380.

A rock is projected from the edge of the top of a building with an initial velocity of 12. 2 m/s at an angle of 63° above the horizontal. The rock strikes the ground a horizontal distance of 25 m from the base of the building. Assume that the ground is level and that the side of the building is vertical. What is the time?.

Answers

The rock travels a horizontal distance x after time t of

x = (12.2 m/s) cos(63°) t

If it hits the ground 25 m away from where it was thrown, then for some time t we have

25 m = (12.2 m/s) cos(63°) t

Solve for t :

t = (25 m) / ((12.2 m/s) cos(63°))

t ≈ 4.5 s

Would sound waves travel slower through air at the north pole or at the equator?.

Answers

yes they would travel slower at the north pole than the equator because the air is more dense and is harder to pass through

Yes, sound waves would travel slower at the North Pole than at the equator because the air is denser and is harder to pass through.

What are equators?

The Equator is the midline of the earth.  A vibration results in a sound. We refer to these motions as "sound waves." Sound waves require a specific medium to travel through. The three different types of media are solid, liquid, and gas.

Keep in mind that since a "solid medium" is denser than the other two, sound waves move through it more quickly. Because water is more densely packed with particles than gas is, sound waves travel faster in liquid than in gas (such as air).

Therefore, yes, because the air is heavier and more difficult to get through at the North Pole than it is at the Equator, sound waves would move more slowly there.

Which best describes the first law of thermodynamics as compared to the second law of thermodynamics?.

Answers

Answer:

The first law describes how thermal energy is conserved but not the direction it moves.

 

Thermodynamics is demonstrated as the branch of physics that deals with the associations or relationships between heat and other energy forms like mechanical, chemical, and electrical).

As per the question, the first law discusses that heat is a kind or form of energy and thus, processes associated with thermodynamics are subject to energy conservation principle. Therefore, heat energy can neither be destroyed nor created but rather transferred to one place to another and converted to and from other energy forms.

Thus, the first law of thermodynamics is distinct from the second law as 'the former describes how thermal energy can be conserved to and from other forms of energy and not the direction in which it moves' while the second law focuses on entropy.

F(x, y) = e−x + y2, e−y + x2 , c consists of the arc of the curve y = cos(x) from − ???? 2 , 0 to ???? 2 , 0 and the line segment from ???? 2 , 0 to − ???? 2 , 0.

Answers

Given that y = cos(x) makes up part of the boundary of C, I suspect you mean the given points to be (-π/2, 0) and (π/2, 0).

I also assume the given vector field is

[tex]\vec F(x,y) = \left\langle e^{-x} + y^2, e^{-y} + x^2 \right\rangle[/tex]

Since [tex]\vec F[/tex] has no singularities on C or in its interior, Green's theorem applies:

[tex]\displaystyle \int_C \vec F(x,y) \cdot d\vec r = \iiint_D \frac{\partial(e^{-y}+x^2)}{\partial x} - \frac{\partial(e^{-x}+y^2)}{\partial y} \, dA = 2 \iiint_D (x + y) \, dA[/tex]

where D is the interior of C, the region

[tex]D = \left\{ (x, y) : -\dfrac\pi2 \le x \le \dfrac\pi2 \text{ and } 0 \le y \le \cos(x) \right\}[/tex]

The integral then reduces to

[tex]\displaystyle 2 \iint_D (x + y) \, dA = 2 \int_{-\frac\pi2}^{\frac\pi2} \int_0^{\cos(x)} (x + y) \, dy \, dx[/tex]

[tex]\displaystyle 2 \iint_D (x + y) \, dA = 2 \int_{-\frac\pi2}^{\frac\pi2} \left( x\cos(x) + \frac12 \cos^2(x) \right) \, dx[/tex]

[tex]\displaystyle 2 \iint_D (x + y) \, dA = 2 \int_{-\frac\pi2}^{\frac\pi2} \left( x\cos(x) + \frac{1 + \cos(2x)}4 \right) \, dx[/tex]

[tex]\displaystyle 2 \iint_D (x + y) \, dA = \frac12 \int_{-\frac\pi2}^{\frac\pi2} \left( 4x\cos(x) + 1 + \cos(2x) \right) \, dx[/tex]

Since 4x cos(x) is an odd function over the symmetric interval [-π/2, π/2], its contribution to the integral is 0, and the remaining integral is trivial.

[tex]\displaystyle 2 \iint_D (x + y) \, dA = \frac12 \int_{-\frac\pi2}^{\frac\pi2} \left( 1 + \cos(2x) \right) \, dx = \boxed{\frac\pi2} [/tex]
