Answer: C

Explanation: after reading it over and over shes the most reasonable. But I could be wrong so be cautious.

According to the question, Maria would be best classified as being in identity diffusion. So, option (C) is correct answer.

What is identity diffusion?

People who are experiencing identity diffusion haven't chosen an ideological or occupational route for the future and aren't making any effort to do so. Identity diffusion occurs during adolescence, a time when individuals are attempting to define their identities, but it can also last into adulthood.

When a person isn't actively forming an identity or committing to one, identity diffusion happens.Many people go through a phase of identity diffusion in their early years of adolescence or in childhood, which they eventually grow out of. Long-term identity diffusion is yet conceivable.James Marcia created four "identity statuses" in the 1960s, and identity diffusion is one of them. These identity statuses are a continuation of Erik Erikson's research on the formation of teenage identities.

In the question, Maria has adopted her parents’ identification as Protestant without considering other options. She   haven't chosen an ideological or occupational route for the future and aren't making any effort to do so.  So, Maria  would be best classified as being in identity diffusion.

these scenarios? AND WHY?

(a) The rock takes the longest time to hit the water in
case 3
(b) The rock takes about the same time to hit the water
in each case
(c) The rock hits the water below with the highest speed
in case 1
(d) The rock hits the water with the same speed in each|
case
Student Answer(s):
Student Reasoning:

Answers

Answer:

The true statement is;

(b) The rock takes about the same time to hit the water in each case

Explanation:

The given information are;

The direction in which the rock is kicked = Horizontally

The number of different initial horizontal with which the rock as kicked =  different horizontal velocity

The time taken for the rock to hit the water is given by the following equation for projectile motion;

y = y₀ + v₀× sin(θ₀)×t - 1/2×g×t²

Where;

θ = The angle the rock makes with the horizontal when it was kicked = 0

y = The height through which the rock drops

y₀ = The initial height of the rock

t = The time taken for the ball to hit the water

g = The acceleration due to gravity ≈ 9.81 m/s²

For the different speeds, v₁, v₂, and v₃, we have;

y = y₀ + v₁× sin(0)×t - 1/2×g×t² = y₀ - 1/2×g×t²

y = y₀ + v₂× sin(0)×t - 1/2×g×t² = y₀ - 1/2×g×t²

y = y₀ + v₃× sin(0)×t - 1/2×g×t² = y₀ - 1/2×g×t²

Therefore, the time it takes for the ball to hit the water is given as follows;

[tex]t = \sqrt{\dfrac{(y_0 - y) \times 2}{g} }[/tex]

Which is the same for each case

However, the speed, v, with which the rock hits the water is given by the following equation;

[tex]v = \sqrt{v_x^2 + v_y^2}[/tex]

[tex]v_y[/tex] = The vertical velocity = v₀ × sin(θ₀) - g×t = v₀ × sin(0) - g×t = -g×t

[tex]v_y[/tex] = -g×t

Therefore, [tex]v_y[/tex], is the same for all three times

While vₓ = v₁, v₂, and v₃, for each of the three times.

Therefore, [tex]v = \sqrt{v_x^2 + v_y^2}[/tex]  the speed with which the rock hits the water is different for all three times.

Answer:

w = 7.5 [J]

Explanation:

We must remember the definition of mechanical work, which tells us that work is equal to the product of force by distance. This force must be applied in the direction of movement. So we have the following equation:

w = F*d

where:

w = work [J]

F = force [N]

d = distance [m]

1st law
4th law

Answers

I think it’s the second law

The given condition satisfies the Newton's First Law of motion. Hence, option (C) is correct.

Given data:

A boy slides down and friction causes him to slow down and stop.

In the given problem, when boy was sliding down, then he was in the state of motion, such that the when the he reaches at the bottom of hill, the friction plays the role of external agent to stop its motion.

This shows that the first law of motion is clearly followed which says that, "If an object is in motion, then it will be in motion until and unless any external force is applied on it". This is also known as law of inertia.

Thus, we can conclude that the given condition satisfies the Newton's First Law of motion. Hence, option (C) is correct.

A punt is kicked at an angle of 60 with a speed of 40 m/s, and lands at the same
height from which it was kicked.

How far away will the ball land?

What is the maximum height reached by the ball?

What is the hang time? Total

Answers

Answer:

1) The ball will land approximately 141.4 m away from where it was kicked

2) The maximum height reached is approximately 61.22 m

3) The total hang time is approximately 7.07 seconds

Explanation:

First we list out the known parameters

The direction in which the punt is kicked, θ = 60°

The speed with which the punk is kicked, v₀ = 40 m/s

1) The distance away (the range, R) the ball will land is given by the equation;

[tex]R = \dfrac{v_0^2 \times sin(2\cdot \theta)}{g}[/tex]

Where;

g =  The acceleration due to gravity = 9.8 m/s²

Substituting the values, gives;

[tex]R = \dfrac{40^2 \times sin(2\times60^{\circ })}{9.8} \approx 141.4 \ m[/tex]

The distance away the ball will land ≈ 141.4 m

2) The maximum height is given m=by the following equation for vertical motion;

(v₀ × sin(θ))² = 2 × g × [tex]h_{max}[/tex]

Obtained from the equation of motion, v² = u² - 2×g×h where at maximum height;

v = 0 at maximum height, the ball stops upward motion

h = Height of motion = [tex]h_{max}[/tex] at maximum height

v, and u are the vertical component of the velocity, v₀

Substituting the values in the equation for the maximum height, gives;

(40 × sin(60))² = 2 × 9.8 × [tex]h_{max}[/tex]

(40 × (√3)/2)² = 1200 = 19.6 × [tex]h_{max}[/tex]

1200 = 19.6 × [tex]h_{max}[/tex]

[tex]h_{max}[/tex] = 1200/19.6 ≈ 61.22 m

The maximum height reached ≈ 61.22 m

3) The time to maximum height is given by the following equation of motion;

[tex]v_y[/tex] = v₀ × sin(θ) - g × t

[tex]v_y[/tex] = 0 at maximum height

We therefore have;

v₀ × sin(θ) = g × t

t =  v₀ × sin(θ)/g = 40 × sin(60°)/9.8 = (40 ×(√3)/2)/9.8 = 3.535 seconds

Given that the motion of the ball is symmetrical about the maximum height, we have;

The time from ground level to maximum height = The time from the maximum height back to the ground level

The total time hang time = The time from ground level to maximum height + The time from the maximum height back to the ground level

The total time hang time ≈ 3.535 + 3.535 ≈ 7.07 seconds.

The total time hang time ≈ 7.07 seconds.

Why are ions formed?
Group of answer choices

A.Because atoms have the same number of protons and electrons

B. Because atoms want 8 valence electrons

C. To make our lives difficult

D. Because atoms gained neutrons

Answers

Answer:

B. Because atoms want 8 valence electrons

Explanation:

Ions are formed because atoms want 8 valence electrons. Most atoms attain stability when they 8 electrons in their outermost shell.

This is the reason why they form ions.

To form ions, atoms will gain or lose electrons or share them. This loss, gain, or sharing of electrons often lead to an atom become stable. One group of atoms, the noble gases, do not form ions readilyThey have complete numbers of electrons in their valence shells. So they do not gain, lose or share their electrons to form ions unlike the others.

Sarah is asked to sort out the list of ions and ionic compounds. How can Sarah differentiate between the ions and ionic compounds? Ions have a positive or negative charge, but an ionic compound's overall charge is zero. Ions have no charge, but ionic compounds have a positive charge. Ions have no charge, but ionic compounds have a negative charge. Ions have a positive or negative charge, but an ionic compound's overall charge is negative.

Answers

Answer:

Ions have a positive or negative charge, but an ionic compound's overall charge is zero.

Explanation:

Ionic compounds are compounds said to contain ions, which are atoms that have either lost electrons to be POSITIVELY CHARGED or gained electrons to be NEGATIVELY CHARGED. The negatively charged ions are called ANIONS while the positively charged ions are called CATIONS.

These cations (+ ions) and anions (- ions) make up ionic compounds in such a way that they give the ionic compound a net charge of ZERO. This is because the charges of the opposite ions that make up the ionic conpound are equal. For example, in the ionic compound CaCl2;

Ca is a cation with charge +2

Cl is an anion with charge -1, 2 atoms make a net charge of -2

When these two ions combine, they cancel out each other to form an ionic compound, CaCl2, with net charge 0 or neutral

Answer:

The answer is

A. Ions have a positive or negative charge, but an ionic compound's overall charge is zero

A ball is shot horizontally at 17.3m/s from the roof of a building 55.2 m tall, (use g = 9.8 m/s ^ 2) How far from the base of the building does the ball land?

Answers

Given that,

The initial speed of a ball, u = 17.3 m/s

It is shot from the roof of a 52 m tall building, h = 52 m

It is required to find the distance from the base of the building the ball land. Let the distance be d.

Final velocity of the ball, v = 0 (when it lands)

We can use third equation of motion to find it.

[tex]v^2-u^2=2ad[/tex]

a = -g

[tex]-u^2=-2gd\\\\d=\dfrac{u^2}{2g}\\\\d=\dfrac{(17.3)^2}{2\times 9.8}\\\\d=15.26\ m[/tex]

So, it will land at a distance of 15.26 m.
