What is the relationship between the sun and the atmosphere? The Sun warms our planet, heating the surface, the oceans and the atmosphere. This energy to the atmosphere is one of the primary drivers our weather. Our climate is also strongly affected by the amount of solar radiation received at Earth. How does the ocean […]

Why is steam so powerful? The water is still nearby, but it’s now in a gaseous form called steam. This form of water is also called water vapor, and it’s very powerful stuff. This is because steam has a lot of energy. This is because as you continue to add more heat, more water molecules […]

Are of light strikes a plane mirror at an angle of 40 degree to the mirror surface What will be the angle of reflection? A ray of light strikes a plane mirror at an angle of 40° to the mirror surface. What will be the angle of reflection? Now, we know that according to the […]

What are Carbohydrates give example? Following are the important examples of carbohydrates: Glucose. Galactose. Maltose. Fructose. Sucrose. Lactose. Starch. Cellulose. What is the basic structure and function of a carbohydrate? Carbohydrates are the most abundant biomolecule on Earth. Living organisms use carbohydrates as accessible energy to fuel cellular reactions and for structural support inside cell […]

Which are not fundamental units? The S.I unit of mass is kilogram (kg), while the S.I unit for acceleration is m/s2. Therefore the S.I unit of force is kg⋅m/s2. Since it is expressed as a combination of the units of mass, length, and time therefore it does not have a fundamental unit. Is Litre is […]

How many oxygen atoms are in 1g of CO2? two oxygen atoms How do you determine the number of oxygen atoms in CO2? of oxygen atoms in 88 g of CO2 contains is 2×2×6.022×1023 atoms. Hence, the no. of oxygen atoms present in 88 g of CO2 is 2.41×1024 atoms. Now, we know that one […]

What is an example of strong nuclear force Brainly? One best example of strong nuclear force is the stability of an atom. Hope this helps u out!! What do you mean by strong nuclear force? The strong nuclear force is sometimes referred to as just the strong force or the strong interaction. This force is […]

What happens if 2 objects have the same speed but different velocities? Objects have the same velocity only if they are moving at the same speed and in the same direction. They represent objects that have different velocities only because they are moving in different directions. A and C represent objects that have different velocities […]

What are the two most important properties of stars? A star can be defined by five basic characteristics: brightness, color, surface temperature, size and mass. Brightness. Two characteristics define brightness: luminosity and magnitude. Color. A star’s color depends on its surface temperature. Surface Temperature. Size. Mass. What is the most important characteristic of a star […]
