Answer:
The approximate absolute brightness is 10,000 and the temperature is 22,000 of the main sequence star.
The approximate absolute brightness is 100-1,000 and the temperature of the giant star is 22,000.
The answer is supergiants.
Explanation:
Hope u do good :)
Chemical properties include corrosive, change in concentration of hydroxide ions when added to water, and forms hydrogen gas when in contact with a metal.
Physical properties of matter are those properties that are determined using senses or instruments. Hence, odor, taste, and texture are physical properties.
The chemical properties of a substance describe how the substance is converted to another substance.
Corrosion is the property of a substance that creates rust under the influence of oxygen from the air.
Some metals in contact with water produce hydroxides where hydrogen is also formed.
A concentration of hydroxide ions in the solution decreases due to dilution when water is added.
Answer:
In a given medium the velocity of a wave is always constant. This means that if the wavelength increases the frequency will decrease and if the frequency increases the wavelength will decrease.
Explanation:
= Wavelength
f = Frequency
Velocity
In a given medium the velocity of a wave is always constant. This means that if the wavelength increases the frequency will decrease and if the frequency increases the wavelength will decrease. This is true for any wave whether sound or electromagnetic.
Answer: B - Both electric and magnetic fields
