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.

Describe how different energy stores are changed by the boiler.
[3 marks]
Answer:
Energy can remain in the same store for millions of years or sometimes just for a fraction of a second. There are energy transfers going on all the time - whenever a system changes there is a change in the way some or all of the energy is stored.
Transferring energy
In each of these examples, energy is transferred by one of the following four types of energy transfer:
mechanical work - a force moving an object through a distance
electrical work - charges moving due to a potential difference
heating - due to temperature difference caused electrically or by chemical reaction
radiation - energy tranferred as a wave, eg light and infrared - light radiation and infrared radiation are emitted from the sun
Doing 'work' is the scientific way of saying that energy has been transferred. For example, a grazing cow, a firing catapult and a boiling kettle are all doing 'work', as energy is being transferred.
Energy flow diagrams
Diagrams can be used to show how energy is transferred from one store to another. Two examples are the transfer diagram and the Sankey diagram.
Transfer diagrams
In transfer diagrams the boxes show the energy stores and the arrows show the energy transfers.
For example, a transfer diagram for a child at the top of a slide may be:
Energy transfer diagram of a child on a slide
Gravitational energy stored in the child at the top of the slide is transferred as mechanical work done to speed up and to do work against friction. The result of this is a shift of energy from gravitational potential energy to kinetic energy and internal energy (raising the temperature of the child and the slide).
Sankey diagrams
Sankey diagrams start off as one arrow that splits into two or more points. This shows how all of the energy in a system is transferred into different stores.
Sankey diagram of a child on a slide
Sankey diagrams are really useful when the amount of energy in each of the energy sources is known. The width of the arrow is drawn to scale to show the amount of energy.

Explanation:
Why does an increase in temperature result in an increase in reaction rate?
Answer:
An increase in temperature typically increases the rate of reaction. An increase in temperature will raise the average kinetic energy of the reactant molecules. Therefore, a greater proportion of molecules will have the minimum energy necessary for an effective collision.
Answer:
When we increase the temperature in a chemical reaction, this increases the particles kinetic energy, making them move much faster than they were before. This also increases collision between the particles and the rate of reaction.
If the speed of sound in air is 340 m/s, approximately how long will it take the sound of a clap of thunder to travel 2 kilometers?(1 point)
5.9 seconds
3.4 seconds
2.9 seconds
1.7 seconds
Answer:5.9 Seconds
Explanation: I just took the quiz
The sound of a clap of thunder take 5.9 seconds to travel 2 kilometers.
To determine the correct statement among all the options, we need to know about the relation between speed and time.
What is sound speed?The speed of sound is the distance travelled by sound per unit time Mathematically, it is v=distance/time= 340m/s.What's is the time taken by sound to travel 2 km?We found 340m/s=distance/time. So, time = distance/340= 2000m/340= 5.9 s.Thus, we can conclude that the sound of a clap of thunder take 5.9 seconds to travel 2 kilometers.

IF you are in Space and push a bowling what happens to you and the bowling ball?
Answer:
The bowling ball did not change size or shape- the only thing that changed was the amount of gravity that pulls on it. But the mass of the bowling ball would never change. A bowling ball with a mass of 12 pounds on earth will have the mass of 12 pounds on the moon! Mass is the amount of atoms that a space fills.

if the battery is a 9-volt battery and the resistance in the circuit is 18 ohm's how much current is flowing through the circuit
Answer:
0.50 A
Explanation:
According to the formula, V = IR
9 = I×18
I = 9/18
I = 0.50
If the battery is a 9-volt battery and the resistance in the circuit is 18 ohm's then the current is flowing through the circuit would be 0.5 Ampere.
Resistance is the obstruction of electrons in an electrically conducting material.The mathematical relation for resistance can be understood with the help of the empirical relation provided by Ohm's law.
V=IR
Where V is the voltage
Where I is the current
Where R is the resistance used in the circuit
As for the given problem if the battery is a 9-volt battery and the resistance in the circuit is 18 ohm
By using the ohms
V=IR
By substituting the respective value of voltage and resistance
Voltage is 9 volt in the resistance is 18 ohm
9V = 18*I
I= 0.5 Ampere
Thus, the current flowing through the 9 V battery and a 18 Ohm resistor is 0.5 Ampere.

So, the value of the resistance of the resistor is 400 Ohm's
1. What happens when like magnetic poles are brought close together?
Answer:
They repel from each other
Explanation:
Answer:
It is also observed that, magnets attract as well as repel. We can explain this dual nature of magnetic force by proposing that each magnet has two poles, north pole (N) and south pole (S). You will observe two things during the activities:
1) When two magnets are brought near each other, like poles repel; opposite poles attract.
2) When a magnet is brought near a piece of iron, the iron also gets attracted to the magnet, and it acquires the same ability to attract other pieces of iron.

Can a physical quantity have units but still be dimensionless?
Answer:
yes
Explanation:
there are other quantities that are dimensionless, but have a unit.
For example, radian is the unit for an angle. But it is dimensionless because it is defined to be the ratio of two lengths.,
a dimensionless quantity will always be independent of the base units — meter, second, kilograms, kelvin, candela, moles, ampere.
Other examples:
1. Mass fraction
2.Mole fraction
both have unit (kg/kg)
Answer:
A quantity that has dimensions must have units. Yes a quantity have units but still be dimensionless for example,unit of angle is radian ,but it is a dimensionless quantity. A dimensionless quantity may have unit. ... A unitless quantity never has a non-zero dimension.

Question 19 of 20
Planets A and B have the same size, mass, and direction of travel, but planet
A is traveling through space at half the speed of planet B. Which statement
correctly explains the weight you would experience on each planet?
A. You would weigh less on planet B because it is traveling twice as
fast as planet A.
B. You would weigh the same on both planets because your mass
would adjust depending on the planet's speed.
O C. You would weigh more on planet B because it is traveling twice as
fast as planet A.
D. You would weigh the same on both planets because their masses
and the distance to their centers of gravity are the same.
SUBMIT
Answer:
D. You would weigh the same on both planets because their masses
and the distance to their centers of gravity are the same.
Explanation:
The above statement is true due to the fact that, the weight and masses of the individual are same in direct comparison with the distance to their center of gravity. If the weight and masses are not same, then there would have been a significant difference between the two planet.
Does the mass of the objects you are charging influence the amount of electric force created in an electric field?
Explanation:
Both gravitational and electric forces decrease with the square of the distance between the objects, and both forces act along a line between them. In Coulomb's law, however, the magnitude and sign of the electric force are determined by the electric charge, rather than the mass, of an object.
