An example of a poor coping mechanism is ?
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.

A large ball of Play-Doh with a mass of 0.04kg is launched from a catapult with an initial
speed of 5m/s and an
initial height of 1.0m. What is the final speed of the ball right before it strikes the ground? Draw a picture!
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.
What is the speed of a rocket that travels 9,000 meters in 12 seconds?
A. 0.001 seconds
B. 750 seconds
C.750 m/s
D. 108,000 m/s
Answer:
750 m/sExplanation:
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
750 m/sHope this helps you
Answer:750m/s
Explanation:I got 750m/s :D Hopefully this helped! lol

When light is directed on a metal surface, the kinetic energies of the photoelectrons a) are random b) vary with the frequency of the light c) vary with the intensity of the light d) vary with the speed of the light
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

The asthenosphere is a part of the upper mantle just below the lithosphere that is involved in plate tectonic movement and isostatic adjustments. Which is NOT true about the role of the asthenosphere in plate tectonics?
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.

On a sunny summer day, why does a white car with a light-colored interior stay cooler than a black car with a dark-colored interior?
Solar radiation reflects off the lighter colours, away from the car, thus keeping the car cool
Solar radiation is absorbed into the lighter colours, keeping the car cool
Solar radiation is absorbed into the darker colours, keeping the car cool
Solar radiation reflects off the darker colours, away from the car, thus keeping the car cool
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.
A 2000 kg minivan runs into a 800 kg car that was at rest at a stop sign and they stick together. If the compact car does not stick to the van but, instead, causes the minivan to come to a complete stop. How fast will the car be going after the collision?
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

Which of the following has the largest momentum?
a. 5kg bowling ball moving with a velocity of 2m/s
b. A 4kg rock rolling down a hill with a velocity of 3m/s
c. A 200kg rock sitting on top of a hill that is 5m height.
d. 0.0025kg bullet that is moving with a velocity of 200m/s
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

How long does it take to run 2000 meters if you run 2 m/s
Answer:
1000 seconds.
Explanation:
[tex] \frac{1}{(1 - \sqrt{3) {}^{2} } } [/tex]
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]
In 1989 Carl Lewis established a world record when he ran the hundred meter dash in 9.92 seconds. What was his average speed (in M/S) for the race? Remember to include your data, equation, and work on solving the problem.
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
Jake and Amir are both standing on identical skateboards and
perform a physics experiment in which they push off one
another to move. Jake is taller and more massive than Amir. If
Jake pushes with 20 N of force, what force would he feel
backwards away from Amir? F= N
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.
