Answer:
Potential energy is the stored energy in an object or thing, while kinetic energy is the energy which an object contains because of a particular motion.
Explanation:
Potential energy is energy that is stored for example a wind up toy, it has energy but in order for you to get kinetic energy, it has to move. So kinetic energy is moving energy.
The difference is that potential is stored and kinetic is moving energy.
Autism is a disability that results from a disorder in the central nervous system. It has been speculated that the increasing number of cases of autism in recent years is due to the increase in the number of vaccinations given to young children. What might be another possible explanation for this phenomenon?
Answer:
Explanation:
As described in the question, autism is a disability that arises from a disorder in the central nervous system which is actually characterized by abnormality in the brain structure and then function. Autism is known for symptoms such as challenges with communication and interaction and some obsessive behaviors. While there is generally no known scientific cause for autism but trends have suggested that vaccination in young children causes autism.
However, genes could also be involved in this phenomenon because there have been reports of unusual genetic sequence in children that have autism. Hence, there is a possibility that vaccination actually triggers this genetic sequence which is then expressed as autism in the children.
Please note this isn't a scientific fact and just a possibility as requested in the question.
AgF (aq) + KNO3 (aq) →
Answer:
AgF (aq) + KNO₃ (aq) → AgNO₃(aq) + KF(aq)
Explanation:
AgF (aq) + KNO₃ (aq) →
The products from the equation above can be obtained as follow:
1. AgF and KNO₃ will dissociate in solution as shown below:
AgF (aq) —> Ag⁺(aq) + F¯(aq)
KNO₃ (aq) → K⁺(aq) + NO₃¯(aq)
2. A double displacement reaction will occur between AgF and KNO₃ as illustrated below:
AgF (aq) + KNO₃ (aq) →
Ag⁺(aq) + F¯(aq) + K⁺(aq) + NO₃¯(aq) → Ag⁺NO₃¯(aq) + K⁺F¯(aq)
AgF (aq) + KNO₃ (aq) → AgNO₃(aq) + KF(aq)
A careful observation of the above equation shows that the equation is balanced.

How do homes lose thermal energy?
I need TWO reasons on why we want to reduce the thermal loose.
Answer:
Poorly insulated attics, windows not being insulated in the winter
Explanation:
One reason is so we do not get cold in the winter and the reason we have a home is to protect us from the weather or put a shelter above us. Second reason is so we don't get hypothermia in the winter time.
Find the mass of an object that has a density of 1.5g/cm^3 and has a volume of 8cm^3 power
Answer:
The answer is 12 gExplanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volumeFrom the question
volume = 8 cm³
density = 1.5 g/cm³
We have
mass = 8 × 1.5
We have the final answer as
12 gHope this helps you
You are a high school track & field coach and you have a young female athlete who is running a competitive mile pace (5:20). This would make her competitive at the state and national level. You want to help this athlete to maintain and even increase her competitive potential. What would you do?
Answer:
By ensuring she is giving speed endurance training
Explanation:
Speed endurance training would be the most ideal in helping an athlete to maintain and even increase her competitive potential.
The speed endurance training would help the athlete maintain and attain a high speed for a longer duration of time.
This would make the athlete get used to running an improved time for much longer distances.

A 2.3 kg object has 15 ) of kinetic energy. Calculate its speed.
O A. 0.12 m/s
OB. 1.1 m/s
O c. 2.4 m/s
OD. 3.6 m/s
Answer:
The answer is option DExplanation:
To find the speed given the kinetic energy and mass we use the formula
[tex]v = \sqrt{ \frac{2KE}{m} } \\ [/tex]
where
m is the mass
v is the speed
From the question
KE = 15 J
m = 2.3 kg
We have
[tex]v = \sqrt{ \frac{2 \times 15}{2.3} } = \sqrt{ \frac{30}{2.3} } \\ = 3.61157559...[/tex]
We have the final answer as
3.6 m/sHope this helps you
A. How many molecules of sugar are in 20.5 g of sugar?
Answer:
By definition, one mole (one gram molecular weight) of any substance, contains Avogadro’s number of particles; atoms if you are discussing an element, or molecules if a compound. Avogadro’s number has been determined by several methods, all of the accepted values lie within a range of +-1% about the value of 6.022045 x 10^23/gm. That is a large number, in this case approximately; 602,204,500,000,000,000,000,000 molecules of glucose.

In each of the following pairs, circle the form of radiation with the LONGER WAVELENGTH:
A. red light or blue light
B. microwaves or radiowaves
C. infrared radiation or red light
D. gamma rays or UV rays
Answer:
In the first one in a it is red light in b it is radio waves in c it is infrared radiation and d is UV radiation
Explanation:
The forms of radiation from the pairs listed that have longer wavelength are :
A) Red light
B) Radio waves
C) Infrared radiation
D) UV rays
Red light have a wavelength between 650 to 720 nm while a Blue light has a wavelength of 380nm to 500nm which makes it to produce a high energy visible light.( HEV ) light. therefore the Red light has a longer wavelength.
The wavelength of a microwave is approximately 30 centimeters to 1 millimeter, which makes it shorter than the wavelength of a radio wave ( shortest wavelength in the electromagnetic spectrum.
Hence we can conclude that The forms of radiation from the pairs listed that have longer wavelength are A) Red light B) Radio waves C) Infrared radiation D) UV rays
