The energy transformations are similar because they result into radiant energy.

As for the lamp, Electrical energy is transformed into light when the filament

or mercury vapor glows on passage of current.

The fire- chemical energy is turned to light energy during the combustion of carbon.  Both products comprise of ultraviolet radiation which is a form of radiant energy.

If the acceleration is 600 m/s/s and the mass is 300 kg, what force is acting on the object?
vampirchik [111]

Explanation:

Acceleration (a) = 600 m/s²

Mass (m) = 300 kg

Force (F) = ?

We know

F = m * a

= 300 * 600

=180000 Newton

The force acting on the object is 18000 Newton.

Explain the difference between complete dominance and codominance.Give an example of each one in order to explain it.
Ira Lisetskai [31]
In complete dominance, only one allele in the genotype is seen in the phenotype. In codominance, both alleles in the genotype are seen in the phenotype. In incomplete dominance, a mixture of the alleles in the genotype is seen in the phenotype.

Why don’t all of the particles in an atom contribute to the mass?
kotegsom [21]

Answer:

Explanation:

The mass of an atom is dependent on its number of protons and neutrons. Electrons have mass, but are too light in comparison to protons and neutrons to contribute towards the overall mass. Their relative mass is about 1/1840 compared to 1 for protons and neutrons, and therefore are not counted in the mass.

Hope this helped!

Which of the following explains how Hahn, Strassman, and Meitner tried to
attashe74 [19]

Answer is: A. They opposed the use of energy released during nuclear fission for military purposes.

Hahn, Strassmann and Meitner were not engaged in nuclear weapons research during World War II.

Otto Hahn (1879 - 1968) became a passionate campaigner against the use of nuclear energy as a weapon.

Hahn and Strassmann discovered nuclear fission (nuclear fission of uranium in 1939).

If a sample of neon gas at 25.00∘C and 0.500 atm is heated at a constant volume until the pressure is 0.850 atm, what must be th
Pie

Answer:

T₂ = 506.6 K

Explanation:

Given data:

Initial pressure of gas = 25°C (25+273 =298 K)

Initial temperature = 0.500 atm

Final pressure = 0.850 atm

Final temperature = ?

Solution:

According to Gay-Lussac Law,

The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.

Mathematical relationship:

P₁/T₁ = P₂/T₂

Now we will put the values in formula:

0.500 atm / 298 K = 0.850 atm /T₂

T₂ = 0.850 atm × 298 K / 0.500 atm

T₂ = 253.3 atm. K / 0.500 atm

T₂ = 506.6 K
