Answer: A bad, maladaptive, unhealthy or destructive coping mechanism is one where the behavior does not resolve the problem in the long-term and may actually increase the harm. Unhealthy coping strategies may feel like they are having the desired effect in the short term.

Answer:

Option b

Explanation:

The formula of momentum is [tex]p=mv[/tex]

where p is the momentum , m is the mass in kg and v is the velocity in m/s, so

a) momentum is

[tex]p=mv\\p=5(2)\\p=10[/tex]

b) momentum is

[tex]p=mv\\p=4(3)\\p=12[/tex]

c) momentum is

here since the rock is sitting on top of a hill which means the object is stationary or in other words the object is at rest, which means if an object is at rest the velocity is 0m/s so momentum is zero of a stationary object because

[tex]p=mv\\p=200(0)\\p=0[/tex]

d) momentum is

[tex]p=mv\\p=0.0025(200)\\p=0.5[/tex]

so the highest momentum is in part b which is 12 so option b is our answer.

Answer:

c

Explanation:

Answer:

\frac{2+\sqrt{3}}{2}

Explanation:

so we simplify tthe denominator first

[tex](1-\sqrt{3})^2=[/tex][tex]4-2\sqrt{3}[/tex]

so the new fraction is:[tex]\frac{1}{4-2\sqrt{3}}[/tex]

We'll ratinalize the fraction to get: [tex]\frac{2+\sqrt{3}}{2}[/tex]

Answer: 20

Explanation:

If Jake pushes with 20 N of force, the force that he would feel backwards away from Amir is 20N

Force simply means the strength or energy that can later the position of an object. Force can also be described as a push or pull.

It should be noted that since Jake pushes with 20 N of force, the force that he would feel backwards away from Amir will be the exact force that was used in pushing.

This will therefore be 20 Newton as well.

Answer:

 v₂ = 2.5 v₁

car leaves at 2.5 times the speed of the minivan

Explanation:

This is an exercise of conservation of the momentum, to solve it we create a system formed by the minivan and the car, therefore during the crash the forces are internal and the momentum is conserved.

Initial instant. Before the crash

        p₀ = M v₁+ 0

Final moment. After the crash

        [tex]p_{f}[/tex] = M 0 + m v₂

how momentum is conserved

         p₀ = p_{f}

         M v₁ = m v₂

         v₂ = [tex]\frac{M}{m}[/tex] v₁

let's calculate

        v₂ = 2000/800 v₁

        v₂ = 2.5 v₁

therefore the car leaves at 2.5 times the speed of the minivan

Answer:

Explanation:

The speed of the rocket can be found by using the formula

[tex]v = \frac{d}{t} \\ [/tex]

d is the distance

t is the time taken

From the question we have

[tex]v = \frac{9000}{12} \\ [/tex]

We have the final answer as

option b )2004........

Answer:

  ≈ 6.68 m/s

Explanation:

A suitable formula is ...

  vf^2 -vi^2 = 2ad

where vi and vf are the initial and final velocities, a is the acceleration, and d is the distance covered.

We note that if the initial launch direction is upward, the velocity of the ball when it comes back to its initial position is the same speed, but in the downward direction. Hence the problem is no different than if the ball were initially launched downward.

Then ...

  vf = √(2ad +vi^2) = √(2·9.8 m/s^2·1.0 m+(5 m/s)^2) = √44.6 m/s

  vf ≈ 6.68 m/s

The ball hits the ground with a speed of about 6.68 meters per second.

__

We assume the launch direction is either up or down.

Answer:

b) vary with the frequency of the light

Explanation:

The phone electric effect can be expressed as

K.E=(hv -W•)

Where K.E is the Kinectic energy

W• = work function of the metal

ν =frequency of the radiation

h = Planck's constat

Then, we can see that K.E is proportional linearly to "v" in the equation above.

Therefore, When light is directed on a metal surface, the kinetic energies of the photoelectrons vary with the frequency of the light

Answer:   Hawk.

Explanation: I dont know for sure, but thats what it looks like to me.

Answer:

10.08 m/s

Explanation:

The average speed of a body or an object can be calculated from the ratio of the total distance traveled by the body/object to that of the time taken to cover the distance.

Mathematically,

Average speed = total distance/total time

The total distance covered by Carl Lewis = 100 m

The total time taken = 9.92 s

Hence,

Average speed of Carl Lewis = 100/9.92

                                         = 10.08 m/s

Answer: Solar radiation reflects off the lighter colours, away from the car, thus keeping the car cool

Explanation: This is because lighter colors reflect a good amount of radiation while darker colors absorb it. Just like, Antarctica hasn't completely melted because it reflects a lot of the heat that is acting upon it. Or, you notice that you get hotter when you wear a black shirt opposed to a white one.

Complete option to the question:

A. The asthenosphere is broken up into large continental- and ocean-sized plates.

B. Convection currents within the asthenosphere push magma upward to create new crust.

C. Heat from deep within Earth is thought to keep the asthenosphere malleable.

D. The asthenosphere is the repository for parts of the lithosphere that are dragged downward in subduction zones.

Answer: The correct option is A (The asthenosphere is broken up into large continental- and ocean-sized plates.)

Explanation:

Among the components that makes up the earth crust are the lithosphere and the asthenosphere.

The LITHOSPHERE is the outer layer of the earth structure which consists of the upper part of the mantle and the crust.

The ASTHENOSPHERE is a part of the upper mantle just below the lithosphere that is involved in plate tectonic movement and isostatic adjustments. It is denser and weaker layer of the upper mantle which permits the movement of tectonic plates in the lithosphere.

The asthenosphere is the repository for parts of the lithosphere that are dragged downward in subduction zones.Heat from deep within Earth is thought to keep the asthenosphere malleable. And the convection currents within the asthenosphere push magma upward to create new crust. But it is not broken up into large continental- and ocean-sized plates.
