What influence do culture and customs have on beliefs about mental disorders? Customs really don't determine what is considered
Mumz [18]

Answer:

The culture of the patient, also known as the consumer of mental health services, influences many aspects of mental health, mental illness, and patterns of health care utilization. One important cautionary note, however, is that general statements about cultural characteristics of a given group may invite stereotyping of individuals based on their appearance or affiliation. Because there is usually more diversity within a population than there is between populations (e.g., in terms of level of acculturation, age, income, health status, and social class), information in the following sections should not be treated as stereotypes to be broadly applied to any individual member of a racial, ethnic, or cultural group.

Whose definition of acids and bases emphasizes the role of protons
torisob [31]

Answer:

Bronsted Lowry

Explanation:

Acid is defined as a proton donor.

While base is a proton acceptor

What is an acid An acid

An acid is a substance that donates protons or accepts a pair of valence electrons to form a bond

What is a base?

A base is a substance that can accept protons or donate a pair of valence electrons to form a bond. Bases can be thought of as the chemical opposite of acids.

A cardboard box sits on top of a concrete sidewalk where the coefficient of friction between the surfaces is 0.4. The mass of th
Sloan [31]

Answer:

Fg = 98.1 [N]; N = 98.1 [N]; Ff = 39.24 [N]; a = 2.076[m/^2]

Explanation:

To solve this problem, we must make a free body diagram and interpret each of the forces acting on the box. In the attached diagram we can find the free body diagram.

The gravitational force is equal to:

Fg = (10 * 9.81) = 98.1 [N]

Now by summing forces on the Y axis equal to zero, we can find the normal force exerted by the surface.

N - Fg = 0

N = Fg

N = 98.1 [N]

The friction force is defined as the product of normal force by the coefficient of friction.

Ff = N * μ

Ff = 98.1 * 0.4

Ff = 39.24 [N]

By the sum forces on the x-axis equal to the product of mass by acceleration (newton's second law), we can find the value of acceleration.

60 - Ff = m * a

60 - 39.24 = 10 * a

a = 2.076[m/^2]

Two skiers arrive at the bottom of a ramp travelling at the same speed. Friction may be ignored in this problem. One skier is an
inysia [295]

Answer:

Both will reach to same height

Explanation:

Here we can see that friction is to be ignored

so we can say that work done by all the non conservative forces is change in mechanical energy

Since all non conservative forces here is zero

so mechanical energy is conserved here

so here we can say that sum of initial kinetic energy and potential energy = sum of final kinetic energy and potential energy

So we will have

\frac{1}{2}mv^2 = mgH

now maximum height is given as

H = \frac{v^2}{2g}

so here we can say that greatest height will be independent of the mass so they both will reach at same height
