Answer:

Insight

Explanation:

In psychology insight has been described as a sudden knowledge or solution that just came up especially after several attempts to solve the problem.Like Amira after spending two hours to solution and she has given up before the solution finally came up. Answers or solutions from insights are more reliable that non-insightful answers.

Gestalt Psychology, a 20th century psychologist was the first to carry out as study on insight where he saw it as a sudden seeing the problem in a new way or linking the problem to other problem or solution pair or release certain blockages prevent one from seeing the solution etc.

In Lesson 20, a magnesium strip was used to ignite the thermite reaction. When magnesium is placed in a flame from a small blow
nadezda [96]

Answer:

2 electrons will be needed by unbound oxygen in order to fill its 2nd shell.

Explanation:

The chemical reaction between magnesium and oxygen gives magnesium oxide as a product.The reaction is chemically represented as:

2Mg(s)+O_2(g)\rightarrow 2MgO(s)

Magnesium is a metal of group-2 with 2 valence electrons.It has atomic number of 12.

[Mg]=1s^22s^22p^63s^2

In order to attain noble gas configuration it will loose two electrons.

[Mg]^{2+}=1s^22s^22p^6

Mg\rightarrow Mg^{2+}+2e^-...[1]

Oxygen is a non metal of group-16 with 6 valence electrons..It has atomic number of 8.

[O]=1s^22s^22p^4

In order to attain noble gas configuration it will gain two electrons.

[O]^{2-}=1s^22s^22p^6

O+2e^-\rightarrow O^{2-}..[2]

2 electrons will be needed by unbound oxygen in order to fill its 2nd shell.

A bus leaves at 9 am with a group of tourists. They travel 350 km before they stop for lunch. Then they travel an additional 250
Anettt [7]

Average speed = Distance traveled / time taken

In this case Time taken = Difference in hours between 3 PM and 9 AM

                                        = 6 hours

Total distance traveled = 350 km + 250 km

                                       = 600 kilometers

So average speed = 600/6 = 100 km/hr

Average speed of bus = 27.78 m/s

So the bus's average speed = 27.78 m/s or 100 km/hr.

An object in static equilibrium has a coefficient of static friction as 0.110. If the normal force acting on the object is 95.0
igomit [66]

Answer:

mass = 9.7 kg

Explanation:

As we know that when object is at rest on the ground of flat base then we will have

N - mg = 0

so from here

N = mg

now we have

N = 95 Newton

now from above equation we will have

95 = m\times g

95 = m\times 9.8

m = 9.7 kg
