Option A, many mental illnesses are used to define an individual, is the right answer.

A disease is a critical unusual condition that adversely influences the structure or performance of a part or full of a person or animals, and that is not due to any outside harm. Therefore, patients suffering from these conditions are called medical disease that can be cured by using medicines. Whereas, mental illness is a behavioral or imaginative exemplar that creates notable suffering or impairment of bodily functions. Thus, the main difference between labeling a person with medical illness and mental illness is that many mental disorders are employed to describe an individual,

You pull with a force of 77 N on a piece of luggage of mass 23 kg, but it does

Vinvika [58]

Answer:

The force of static friction acting on the luggage is, Fₓ = 180.32 N

Explanation:

Given data,

The mass of the luggage, m = 23 kg

You pulled the luggage with a force of, F = 77 N

The coefficient of static friction of luggage and floor, μₓ = 0.8

The formula for static frictional force is,

Fₓ = μₓ · η

Where,

η - normal force acting on the luggage 'mg'

Substituting the values in the above equation,

Fₓ = 0.8 x 23 x 9.8

= 180.32 N

Hence, the minimum force require to pull the luggage is, Fₓ = 180.32 N

Daniel [21]

Answer:

$v_2=-133.17m/s$ , the minus meaning west.

Explanation:

We know that linear momentum must be conserved, so it will be the same before ( $p_i$ ) and after ( $p_f$ ) the explosion. We will take the east direction as positive.

Before the explosion we have $p_i=m_iv_i=Mv_i$ .

After the explosion we have pieces 1 and 2, so $p_f=m_1v_1+m_2v_2$ .

These equations must be vectorial but since we look at the instants before and after the explosions and the bomb fragments in only 2 pieces the problem can be simplified in one dimension with direction east-west.

Since we know momentum must be conserved we have:

$Mv_i=m_1v_1+m_2v_2$
