What might be a reason conflict arises?

Katena32 [7]

D- all of the above

Explanation:

Conflict is a clash between different ideas and people.

It can be as a result of the misunderstanding of another person's point of view. This is one of the leading causes of conflict. A party can take another party's view verbatim without understanding the context behind a reasoning. Through this, conflict can ensue.
It can also be due to non-compatible personalities. This can be between an extrovert and introvert or a blend of them.
Different values can also lead to conflict. It can be a cultural or religious thing.

Alex is asked to move two boxes of books in contact with each other and resting on a rough floor. He decides to move them at the

Over [174]

Answer:

Part a)

$a= 0.32 m/s^2$

Part b)

$F_c = 3.6 N$

Part c)

$F_c = 5.5 N$

Explanation:

Part a)

As we know that the friction force on two boxes is given as

$F_f = \mu m_a g + \mu m_b g$

$F_f = 0.02(10.6 + 7)9.81$

$F_f = 3.45 N$

Now we know by Newton's II law

$F_{net} = ma$

so we have

$F_p - F_f = (m_a + m_b) a$

$9.1 - 3.45 = (10.6 + 7) a$

$a = \frac{5.65}{17.6}$

$a= 0.32 m/s^2$

Part b)

For block B we know that net force on it will push it forward with same acceleration so we have

$F_c - F_f = m_b a$

$F_c = \mu m_b g + m_b a$

$F_c = 0.02(7)(9.8) + 7(0.32)$

$F_c = 3.6 N$

Part c)

If Alex push from other side then also the acceleration will be same

So for box B we can say that Net force is given as

$F_p - F_f - F_c = m_b a$

$9.1 - 0.02(7)(9.8) - F_c = 7(0.32)$

$F_c = 9.1 - 0.02 (7)(9.8) - 7(0.32)$

$F_c = 5.5 N$

What happens to the negative charges

Nikitich [7]

Answer:

<em>The correct option is C) spreads out over a large area on the object. </em>

Explanation:

In physics, a ground can be described as a reservoir object in which charge can be stored. Grounding refers to the removal of charge in an object by using the ground object. When an object with excess if charge is placed on the ground object, the electrons are transferred from the charges object to the ground object. This charge begins to spread evenly in the ground object with the passage of time.

When a train first starts going down the railroad, it is very difficult for it to get going. When it comes to a stop, it has a h

Sindrei [870]

<h2>The option ( c ) is correct</h2>

Explanation:

When we apply the force on any body , the inertia comes into play . It is the tenancy of the the body to oppose the force which tends to change its state .

In first case the train tries to change its state from rest to motion . Thus the inertia of rest opposes this tendency.

In the second case , the train tries to come from motion to the state of rest . Thus again , inertia opposes it .

Therefore inertia is the factor which creates difficulty in both case . Hence option ( c ) is correct
