Anxiety disorders are not completely curable.
What are anxiety disorders?An anxiety disorder is a disorder in which an individual easily develops feelings of anxiety even in situations which do not warrant such feeling.
The individual feels excessively anxious that it becomes a disability and does not allow the individual to live a normal life.
There are five main types of anxiety disorders and they are as follows:
Generalized Anxiety DisorderObsessive-Compulsive DisorderPanic DisorderPost-Traumatic Stress DisorderSocial Phobia or Social Anxiety DisorderAnxiety disorders are not completely curable since they are purely psychological problems.
However, therapy and psychological assistance can lessen symptoms.
In conclusion, anxiety disorders affect productivity and makes an individual excessively anxious.

Kellie is hopping on one foot. Kellie has a mass of 650
newtons and her foot has an area of 0.10 m2.
How much pressure is exerted by her foot on the ground
with each hop?
Answer:
650 N / 0.10 m2 = 6500 Pa
Explanation:
The pressure that could be exerted on the ground with each top should be 6,500 Pa
Given that,
The mass is 650 newtons.The area should be 0.10m^2We need to determine the pressure.
So, the following formula should be used.
[tex]= \frac{Mass}{area}\\\\= \frac{650}{0.10} \\\\[/tex]
= 6,500 Pa
Therefore we can conclude that the pressure that could be exerted on the ground with each top should be 6,500 Pa.

The difference between a Scalar quantity and a Vector quantity?
Answer:
A quantity that has magnitude but no particular direction is described as scalar. A quantity that has magnitude and acts in a particular direction is described as vector.
How does the value and direction of the restoring force change as the spring constant or displacement is changed?
Answer:
The effect of gravity is only to shift the equilibrium point, so at equilibrium (at rest), a vertical spring will be extended as compared with the same spring in a horizontal position. But this does not affect the period.
As the spring constant or displacement is changed, the value and direction of the restoring force change, and they are always toward the equilibrium position of the spring when it is stretched.
What is the significance of the restoring force?When an object is relaxed or stretched, it is responsible for returning it to its original equilibrium position, such as a spring when stretched, and the force is directly proportional to the displacement and acts in the opposite direction of the displacement, the restoring force is responsible for the oscillations and waves, and its properties.
Hence, as the spring constant or displacement is changed, the value and direction of the restoring force change, and they are always toward the equilibrium position of the spring when it is stretched.

Explanation:
A man pushed the box with a force of 20 N. The mass of the box doubled, but he still pushed with a force of 20 N.
Which option describes how the acceleration of the box after the mass was doubled?
a) The acceleration is 2x the original acceleration
b) Acceleration is 4x the original acceleration
c) Acceleration is 1/2x the original acceleration
d) Acceleration is 1/4x the original acceleration
Answer:
Option (c) Acceleration is 1/2x the original acceleration
Explanation:
To know the the correct answer to the question, we shall determine the acceleration of the box in each case.
Case 1:
Mass (m) = m
Force (F) = 20 N
Acceleration 1 (a₁) =?
F = ma₁
20 = m × a₁
Divide both side by m
a₁ = 20 / m
Case 2:
Mass (m) = 2m
Force (F) = 20 N
Acceleration 2 (a₂) =?
F = ma₂
20 = 2m × a₂
Divide both side by 2m
a₂ = 20 / 2m
a₂ = 10 / m
Finally, we shall determine the acceleration of the box after the mass was doubled. This can be obtained as illustrated below:
Acceleration 1 (a₁) = 20 / m
Acceleration 2 (a₂) = 10 / m
a₂ : a₁ = 10 / m : 20 / m
a₂ / a₁ = 10 / m ÷ 20 / m
a₂ / a₁ = (10 / m) × (m / 20)
a₂ / a₁ = ½
Cross multiply
a₂ = ½a₁
Thus, the acceleration of the box after the mass was doubled is ½ times the original acceleration.

Reflection of light (and other forms of electromagnetic radiation) occurs when the waves encounter a surface or other boundary that does not absorb the energy of the radiation and bounces the waves away from the surface. The simplest example of visible light reflection is the surface of a smooth pool of water, where incident light is reflected in an orderly manner to produce a clear image of the scenery surrounding the pool. Throw a rock into the pool (see Figure 1), and the water is perturbed to form waves, which disrupt the reflection by scattering the reflected light rays in all directions.
Some of the earliest accounts of light reflection originate from the ancient Greek mathematician Euclid, who conducted a series of experiments around 300 BC, and appears to have had a good understanding of how light is reflected. However, it wasn't until a millennium and a half later that the Arab scientist Alhazen proposed a law describing exactly what happens to a light ray when it strikes a smooth surface and then bounces off into space.

Heat always flows from a
place to a
place.
Heat always flows through from a higher thermodynamic potential to lower thermodynamic potential.
What is thermodynamics?It can be defined as the branch of science that deals with the interactions of thermal energy across different system and their surroundings.Thermodynamics does not deal with the rate of energy interaction.The movement of the thermal energy depends on the thermodynamic potential of the respective objects or bodies in which the flow of the thermal energy is involved.
The thermodynamics potential is analogous to the electrical potential what is used to flow the current in the electrical circuit in the similar fashion the temperature gradient is the driving force that is used for the transfer of heat energy from a higher temperature potential to the lower to a temperature potential.
This natural flow of heat is valid only when any external work is not done on the thermodynamic system where transfer of heat taking place .
This principle of heat transfer is not applicable in the case of refrigerator and air-conditioner because in that case some external work is done on the system and is the natural driving force of heat transfer.
Hence,we can say that heat always flows through from a higher thermodynamic potential to lower thermodynamic potential unless until some external prime mover is provided for example in case of air conditioner.

Your are on a boat on a lake with no current. The lake is full of sharks that will eat you if you put your hands too close to the water, and your paddle has been eaten by those sharks. However, you do have a big bucket of grapefruit in the boat. How will you get to shore? Your answer must reference Newton's third law.
Answer:
i would use the grapefruit and throw it into the water 1 by 1 one leaving sometime in between to see the sharks reaction to it. If they get attracted to it i would throw 1 in then use the bucket to push foward as fast as i can with all of my strength so i can get an equal and opposite reaction from the water to push me foward, i would keep this up for as long as i can. The size of the bucket and the amount of grapefruit were never specified so i would use this for my benefit to say its enough to get to shore

The total work done to move the lift to this height if, A lift that weighs 300 N moves a man with a weight of 950 N upwards by 12 m, is 15000 Joules.
What is work done?When an object is moved over a distance by an external force, at least a portion of that force must be applied in the direction of the displacement. This is known as work in physics.
Given:
A lift that weighs 300 N moves a man with a weight of 950 N upwards by 12 m,
Calculate the total force as shown below,
Total force = Lift weight + man weight
Total force = 300 + 950
Total force = 1250 N
Calculate the work done as shown below,
The work done = Total force × displacement by total force
The work done = 1250 × 12
The work done = 15000 Joules
Thus, the total work done is 15000 joules.

Rahul has 2 bulbs connected across two cells in a simple circuits shown. How can he make the bulbs glow dimmer?
Answer:
in the parallel connection the light bulbs shine less than in the series connection
Explanation:
In a series circuit the current through the whole circuit is the same, therefore the power (brightness) of each bulb is
P = i² R
where R is the resistance of each bulb and i the current of the circuit.
If we connect the light bulbs and the cells in parallel, the current in the circuit is the sum of the east that passes through each light bulb,
i = i₁ + i₂
if the two light bulbs are the same
i = 2 i₁
i₁ = i / 2
so the power of each bulb is is
P = i₁² R
P = R i² / 4
P = ¼ P_initial
Therefore we see that in the parallel connection the light bulbs shine less than in the series connection
