The Answer Is Number Of Neutrons!
Scientific knowledge can be modified. This is because all the scientific principles that are existing now is not certain for all possible conditions. Scientific knowledge is not directly given to us, human minds work the effort of unveiling the unknown. Thus, scientists are slowly discovering the science of all natural phenomena. Along the way, they could come up with misinterpretations. Let me give a concrete example. When J.J. Thompson proposed the Plum-Pudding model, it was the widely accepted theory in the field of atomic science. However, when Rutherford did his golden foil experiment, he disproved Thompson's model and proposed the Planetary Model. Therefore, scientific knowledge is an ongoing process. Scientists would always want to disprove each other, not because they want to compete with each other. They want to discover the truth together with what they have to the best of their abilities. They are never content with just one simple principle according to one scientist. It will always be verified by a group of fellow scientists.
In the 21st century where technology is exponentially progressing, scientists would discover more of the basic principles. Hence, we would expect that scientific knowledge is constantly changing and modifying.
You know that the formula for finding horizontal displacement is;
s=uₓt
s=(5 m/s)(3s)
s=15 m
Therefore, the ball travelled 15 m.

Answer:
If we use a mixture of red and blue light, the blue toy car might reflect deep magenta color. If the toy car is made up of metal, it might reflect glittery magenta color. If the intensity of the blue color is greater, the toy car might show dark blue color

is this right please let me know:D
Answer:
25 min, 48 sec
Explanation:
Alan:
t = d/v
= 400 mi / 46 mph = 8.70 hr
So it took Alan 8.70 hrs; from 8 am, that's 4:42 pm that he arrives.
t = d/v
= 400 mi / 55 mph = 7.27 hr
So it took Beth 7.27 hrs; from 9 am, that's 4:16:12 that she arrives.
4:42 - 4:16:12 = 25.8 minutes = 25 minutes, 48 sec
