Kinetic energy is the energy possessed by an object due to its motion. If an object is moving, then it has kinetic energy. If an object has kinetic energy, then it is moving. Many students confuse kinetic energy with potential energy.
Is neon transparent translucent or opaque
Neon is transparent opaque as it is light, colorless and order less inert noble gas.
What are noble gas?Noble gas are defined as the element that belong to group 18 of the modern periodic table.
It is also known as inert gas or aerogene.
Noble gas are light, transparent, colorless and order less gases.
They are the group of six inert or non reactive gases.
Noble gases are odorless, colorless, nonflammable gases with negligible chemical reactivity.
Noble gases are exceedingly stable and unlikely to form chemical bonds due to their complete valence electron shells, which have no tendency to add or lose electrons.
Noble gas were originally classified as group 0 in the periodic table because it was thought they had a valence of zero, which means their atoms could not mix with those of other elements to form compounds.
Thus, Neon is transparent opaque as it is light, colorless and order less inert noble gas.

8. Converting Units The volumes in your data are in millimeters, which are equivalent to cubic centimeters, cm3. But your areas are in units of square meters (m2). To combine these, you will have to convert to similar units. Convert one of your volume measurements from units of cm3 to units of m2, showing your work. (Remember that 1 ×106 cm3 = 1 m2.)
Answer:
This question is a practical question and hence incomplete
Explanation:
However, there are some steps that can be followed to achieve the aim of this question.
To convert millimeters (mm) to cubic centimeters (cm³), the value in millimeter will have to be divided by 1000. This is because 1 mm equals 0.001 cm³. Hence, if the volume in the data is 30 mm, the equivalent in cm³ will be
30/1000 = 0.03 cm³
OR
1 mm ⇒ 0.001 cm³
30 mm ⇒ ?
Let's assume the unknown (?) is X
1 × X = 30 × 0.001
X = 0.03 cm³
Hence, 30 mm equals 0.03 cm³
Also, to convert any volume from cubic centimeter (cm³) to square meter (m²), you will divide the unit in cm³ by 1 × 10⁶ (1,000,000). To convert the value obtained earlier (0.03 cm³ or 3 × 10⁻² cm³) to m², you will
1,000,000 cm³ ⇒ 1 m²
0.03 cm³ ⇒ ?
Let's assume the unknown (?) is Y
1000000 × Y = 0.03 × 1
Y = 0.03/1000000 OR you can write it as 3 × 10⁻² × 10⁻⁶
Y = 3 × 10⁻⁸m²
Hence, 0.03 mm equals 3 × 10⁻⁸ m²

1. When electrical energy is used what type of energy is also produced and considered to be waste energy? Thermal energy Mechanical energy Nuclear energy Radiant energy
Answer:
Energia solar: é proveniente de uma fonte inesgotável: o Sol. Os painéis solares possuem células fotoelétricas que transformam a energia proveniente dos raios solares em energia elétrica. Tem a vantagem de não produzir danos ao meio ambiente.
Energia nuclear: energia térmica transformada em energia elétrica, é produzida nas usinas nucleares por meio de processos físico-químicos.
Energia eólica (ar em movimento): ela já foi utilizada para produzir energia mecânica nos moinhos. Atualmente é usada com o auxílio de turbinas, para produzir energia elétrica. É atraente por não causar danos ambientais e ter custo de produção baixo em relação a outras fontes alternativas de energia.
A energia elétrica também pode se transformar em outros tipos de energia ao chegar às residências ou em indústrias. Exemplos:
Energia térmica: quando vamos passar roupas, a energia elétrica é transformada em energia térmica através do ferro de passar.
Energia sonora e energia luminosa: recebemos iluminação em casa pela transformação da energia elétrica que, ao passar por uma lâmpada, torna-se incandescente, e o televisor nos permite receber a energia sonora.
Energia mecânica: usada nas indústrias automobilísticas para trabalhos pesados.

The atomic radius of magnesium is 150 pm. The atomic radius of strontium is 200 pm. What is the atomic radius of calcium
Answer:
The atomic radius of calcium is approximately 175
Explanation:
Given that the atomic radius of magnesium = 150 pm
The atomic radius of strontium = 200 pm
Therefore, given that calcium comes in between magnesium and strontium in group 2 of the periodic table, the atomic radius should be half way between the length of the atomic radius of magnesium and strontium, given that the atomic radius is not a fixed quantity
Therefore;
The atomic radius of calcium is approximately given as follows;
The approximate atomic radius (200 + 150)/2 = 175 pm.
What is the relationship between a white dwarf and black dwarf?
Answer:
No longer emitting heat or light, the white dwarf will become a black dwarf. Because it emits no radiation, it is nearly impossible to see. However, the black dwarf would still retain its mass, allowing scientists to detect the effects produced by its gravitational field.
Explanation:
Answer:
white dwarfs are hot, black dwarfs are cold
Explanation:
a white dwarf is a slowly burning and aging corpse of a main sequence star such as our sun. they are up to 40 times hotter then the sun, ranking among one of the hottest objects in the universe, except their luminosity is so low that all their heat stays in them basically forever.
On the other hand, a black dwarf is a theoretical ending to a white dwarf, over the course of trillions of years, white dwarfs cool down into black dwarfs. black dwarfs rank among the coldest possible temperature. We aren't sure if these are really a thing, because we still haven't given white dwarfs enough time to cool down.

Calculate the heat that must be supplied to
a 532 , stainless steel vessel containing 375 g
of water to raise its temperature from 35 C
to the boiling point of water 100°C. Cs. =0.51 J/g. degrees C
Answer in units of J.
Also what percentage of the heat is used to raise the temperature of the water?
Answer:
Q must be supplied = 119523.3~J
Explanation:
The law of conservation of energy can be applied to heat changes, i.e. the heat received/absorbed is the same as the heat released
Q in = Q out
Heat can be calculated using the formula:
Q = mc∆T
Q = heat, J
m = mass, g
c = specific heat, joules / g ° C
∆T = temperature difference, ° C / K
So from the question :
Q to the system(Q supplied) = Q water + Q steel vessel(Q gained)
