Answer:
I think answer is
-the waves transfer energy
The answer to the question is B
Answer:
The would both accelerate because they have the same amount of mass and your applying the same force.
Explanation:
In an atom, there are basically 3 structural parts, protons, neutrons, and electrons. Protons and neutrons makes up the nucleus, meanwhile the electrons move around the nucleus.
Atomic number equals the number of protons in an atom. It's like a code for each atoms from an element, they're fixed, for example for hydrogen , it has 1 proton, therefore it's atomic number is 1.
In the other hand, the atomic mass is the total number of the protons and neutrons added up. This can be different for the same element because there may be different numbers of neutrons for the atoms. But you don't have to memorize the atomic mass, you calculate it in exams.
For example if an atom has the number of proton of 1, and neutron of 1, their atomic mass would be 2.
Few advancements in scientific knowledge were made.
Scientists discovered new evidence to support their theories.
Scientists used observations and mathematical data to solve problems in new ways.
<u>Explanation:</u>
At first the Ptolemaic model suggested that the earth was the centre of the solar system around which the sun, moon and other planets revolved. This Copernican revolutionised by finding Sun in the centre of the solar system around which the earth and the other planets revolved. After his discovery the earth was just given a status of yet another planet.
The scientists who were researching on this made few advancements using their scientific knowledge and hence found new evidences to support their theory. Scientists then researched conducted experiments using mathematical calculations to solve their problems.
