Answer:

The energy that makes light is 'produced' when you pass a high-voltage alternating current through a low-pressure gas sealed in a glass tube.

Explanation:

Answer:

1)The molar mass of an atom is simply the mass of one mole of identical atoms. However, most of the chemical elements are found on earth not as one isotope but as a mixture of isotopes, so the atoms of one element do not all have the same mass.

2)Equally important is the fact that one mole of a substance has a mass in grams numerically equal to the formula weight of that substance. Thus, one mole of an element has a mass in grams equal to the atomic weight of that element and contains 6.02 X 1023 atoms of the element.

Answer:

Empirical formula is CH₃Cl.

Explanation:

Given data:

Percentage of hydrogen = 6%

Percentage of carbon = 24%

Percentage of chlorine= 70%

Empirical formula = ?

Solution:

Number of gram atoms of H = 6/ 1 = 6

Number of gram atoms of C = 24 /12=  2

Number of gram atoms of Cl = 70/ 35.45 = 2

Atomic ratio:

            C                      :      H            :         Cl

           2/2                    :     6/2           :       2/2

            1                       :        3          :        1

C : H : Cl = 1 : 3 : 1

Empirical formula is CH₃Cl.

Answer:

Answer:

λ = 0.032×10² m

Explanation:

Given data:

Frequency of broadcasts = 94.7 MHz

Wavelength of broadcasts = ?

Solution:

Frequency of broadcasts = 94.7× 10⁶ Hz

Formula:

Speed of wave = frequency × wavelength

3×10⁸ m/s = 94.7× 10⁶ Hz × λ

λ = 3×10⁸ m/s /94.7× 10⁶ Hz

 Hz = 1/s

λ = 0.032×10² m

Explanation: In writing the electron configuration for oxygen the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for O go in the 2s orbital. The remaining four electrons will go in the 2p orbital. Therefore the O electron configuration will be 1s22s22p4.

They have no true nucleus as the DNA is not contained within a membrane or separated from the rest of the cell, but is coiled up in a region of the cytoplasm called the nucleoid. Prokaryotic organisms have varying cell shapes.

Explanation:

Answer:

Explanation:

The DNA in prokaryotes is contained in a central area of the cell called the nucleoid, which is not surrounded by a nuclear membrane. Many prokaryotes also carry small, circular DNA molecules called plasmids, which are distinct from the chromosomal DNA and can provide genetic advantages in specific environments.

Answer:

It comes from same parent material.

Explanation:

The two rocks have some similar minerals which indicates that they are comes from the same parent material but with the passage of time it is mixed with other minerals due to which they are some different in composition from one another so we can conclude that they comes from the same parent material due to the presence of some similar minerals.

Answer:

If two forces act on an object in the same direction, the net force is equal to the sum of the two forces. This always results in a stronger force than either of the individual forces alone

Answer:

Antarctica and Australia

Explanation:

Since both of these are furthest south it is more difficult to measure the correct distance between them.

The continents that were the hardest to locate were Antarctica and Australia because they are both the ones that are the furthest south, making it more challenging to calculate the proper distance between them.

A continent is a huge, continuous landmass on the surface of the Earth, typically divided by oceans or other major bodies of water. Africa, Antarctica, Asia, Europe, North America, Australia, and South America are the seven continents of the world. In terms of topography, climate, culture, and biodiversity, each continent is distinct. For instance, Asia is home to the Himalayas, the world's highest mountain range, while Africa is renowned for its huge savannas and diverse animals. While Australia is well known for its distinctive flora and wildlife, Europe is known for its historical sites and artistic creations.

Explanation:

Answer: argon

Explanation:

using the last clue “avg atomic mass of 3.33x greater than carbon-12” we can deduce the atomic mass of the element is 12x3.33=40(2sf) hence its argon. we can further confirm from third clue that it is a noble gas hence unreactive

Answer:

Normal force

Explanation:

normal force always perpendicularly points away from a surface

Normal force is the equal and opposite force for the Earth's force of gravity pulling down on the person as described by Newton's third law.

Force is defined as a cause which is capable of changing the motion of an object. It can cause an object which has mass to change it's velocity. It is also simply a push or a pull . It has both magnitude as well as direction.Hence, it is a vector quantity.

It has SI units of Newton and is represented by'F'.Newton's second law states that force which acts on an object is equal to momentum which changes with time. If mass of object is constant, acceleration is directly proportional to net force acting on an object.

The concepts which related to force are thrust and torque .Thrust increases the velocity of an object and torque produces change in rotational speed of an object.
