How are luminosity, apparent mange, and absolute magnitude different? How are they similar?

Answers

Answer 1
The magnitude of a star as it would appear to a hypothetical observer at a distance of 10 parsecs or 32.6 light-years. This rates how visible celestial bodies are when they are all viewed from the same distance. Luminosity: The brightness of a star in comparison with that of the sun.

How does changing the mass of a wheelchair affect its velocity?

Answers

It might slow it down? Velocity is the measure of of distance, rate and time. If you are doing it on an actual wheelchair, try test running experiments with and without the wheelchair?

Explanation:

Mass and velocity are inversely propotional, which means that if you increase the mass of the wheelchair the velocity would automatically decrease, similarly, if you decrease the mass of the wheelchair the velocity of the wheelchair would increase.

The melting point of a substance is characteristics to it. Hence, we can identify a compound by calculating its melting point. If the solids are pure they will give their characteristic actual melting point.

What is melting point?

Melting point of a substance is the temperature at which it converts from solid state to liquid state where, the two phases are in equilibrium. Melting point is dependent  upon the intermolecular forces, molar mass, temperature and presence of impurities.

Melting point of a pure substance is a characteristic feature for it. Hence, we can qualitatively test a compound using its melting point and using standard dats of melting points we can identify the substance.

Conductivity, solubility etc. are not characteristic for a substance and can be similar to other solids. Therefore, option A melting point tests helps to identify A and B.

How could a change to the size of the algae population cause an increase in the size of the moon jelly population? (Be sure to discuss births and deaths in your answer.)
(they had no science option)

Answers

To reproduce, organisms need to release energy from energy storage molecules. If there are more energy storage molecules available to the moon jellies, they can reproduce more, resulting in more births. Fewer deaths would also cause the jelly population to increase. ... As a result, the moon jelly population increased.

A change to the size of the algae population cause an increase in the size of the moon jelly population if there are more energy storage molecules available to the moon jellies, they can reproduce more, resulting in more births.

What is an Algal Bloom?

The rapid increase or aggregation in the algae population of freshwater or marine water systems is termed an algal bloom. It is often identified by water discolouration due to the algae’s pigment.

The term algal bloom typically refers to the rapid multiplication of microscopic algae rather than macroscopic ones.

Algae are always present in natural bodies of water like oceans, lakes, and rivers, but only a few types can produce toxins.

In these algae, toxin production can be stimulated by environmental factors such as light, temperature, and nutrient levels.

Therefore, A change to the size of the algae population cause an increase in the size of the moon jelly population if there are more energy storage molecules available to the moon jellies, they can reproduce more, resulting in more births.

Why might hydrogen be a wonderful fuel for the future?

Answers

Answer:

In the future, hydrogen will join electricity as an important energy carrier, since it can be made safely from renewable energy sources and is virtually non-polluting. It will also be used as a fuel for 'zero-emissions' vehicles, to heat homes and offices, to produce electricity, and to fuel aircraft.

Answer:

It can be a wonderful fuel, because unlike other sources of power generation, it produces no greenhouse gas and hence does not contribute in polluting the environment or causing global warming. However it can be a dangerous fuel as well, as it is highly flammable.

Sound waves travel as particles of matter collide and transfer energy.

True

False


6

Answers

true

sound travels as energy, unlike light.. the waves transmit energy by changing the motion of particles. The particles are moving in the same direction as the wave.

Answer:

True

Explanation:

Sound waves require a medium/substance to transmit through, for example, sound waves cannot travel through the vacuum of space . The medium, water or air, itself does not move in bulk with the wave . The medium's particles carry kinetic energy from one point to another . This is when the wave transmits through its medium, the particles simply vibrate as the wave passes through. The vibrations carry the energy from one particle to the next. This means that the sound wave is carried through the medium.

*Note: Sound waves need particles to travel but light does not.

Answers

Creating individually unique cells
I agree. In genetic diversity, specifically in meiosis, can create individually unique cells. Meiosis is a process of cellular division where the cell splits into four daughter cells with half the chromosomes from the parent cell. It is similar to mitosis except the fact that mitosis splits in two cells and are genetically identical, where’s meiosis had different unique cells that split in four. So the answer is C, by creating individually unique cells. Hope this helps. Give me brainiest!
