Answer:

The photons undergo innumerable collisions and interactions as they travel from atom to atom.

Explanation:

The sun is a massive body in which nuclear reaction takes place. It involves the nuclear fusion of  hydrogen atoms to produce  He atom. The Helium atom has less mass than the combination of the hydrogen atoms. The excess mass is converted to energy.

Electric charge is conserved in nuclear reactions. A positron otherwise called an anti-matter electron hits a close electron and they produce electromagnetic radiation in form of gamma rays.

x-rays are produced from gamma rays are gamma rays lose energy to nearby particles as they move towards the surface of the sun which in turn becomes ultraviolet rays. in the course of the journey to the surface of the sun, photons must have lost enough energy and be converted to visible light which we can see. The whole process happens over a 100,000years.

Which sentence is a scientific statement?
LekaFEV [45]

Solution: Sentence D is a scientific statement.

Scientific statement is a statement that defines the science behind any situation. There should be any experimental result or observation to state any scientific statement. Also, the statement should be accepted by considering other scientific aspects.

Here, statement A can not be a scientific statement as different aromas of cooked food are liked by different people. Any one can find aroma of cooked food in copper better than the ceramic pot.

Thus, the statement can be proved wrong easily.

Statement B can not be a scientific statement as people can find the taste of normal water (without ice cubes) better than the ice cold water.

Statement C is not a scientific statement as there is no science behind watching baseball or ice hockey, it depends on the liking of today's people.

Statement D is a scientific statement because this can be scientifically proved.

True or false if an object displaces 50 ml of water the object's volume is 50mL
andrew11 [14]

Answer:

True

Explanation:

The volume of water displaced by an object completely submerged is its actual volume. It implies that in the container the object create a space of size for itself which is the volume of the object. This approach is used in calculating the density of many irregular solids from their measured masses.
