Answer:
T = (99.78 ±0.05) ºC
Explanation:
This problem refers to the procedure to perform the measurements and their correct reporting.
Suppose that the thermometer used has an appreciation of 0.1ºC and the values of 5 measurements resulted in
# T (ºC)
1 99.8
2 99.7
3 99.7
4 99.8
5 99.9
the processing calculate mean value
T_average = ∑ 
/ n
T_average = (99.8 + 99.7 + 99.7 + 99.8 + 99.9) / 5
T_average = 99.78ºC
the absolute error or uncertainty of the measurement is half the appreciation of the instrument
ΔT = ± 0.05ºC
so the result must be written
T = (99.78 ±0.05) ºC

Matter can be many things, but is mostly made of atoms. Atoms are small things that cannot be seen directly, as lights either passes through it or alters it. However, we know that atoms are made of 3 parts, those being the proton, neutron, and electron.
Protons have a positive electromagnetic charge.
Neutrons have no charge.
Electrons have a negative charge equal to the protons positive charge.
Protons and neutrons make up what's called the nucleus, which is orbited by the electrons.
Protons and neutrons also share another thing in common, that being their composition.
Until relatively recently, we thought that these were the smallest particles in the universe, and indestructible. However, modern discoveries have revealed that they are actually made of quarks and gluons.
These are actually indestructible, being part of the group that is elementary particles.
Answer:
No
Explanation:
Recall that the hierarchy of wavelength color from minimum wavelength to maximum wavelength is:
and
As a result, blue light has a higher energy level than green and red light.
As a result, the surface glows due to the blue LED. The green LED, on the other hand, would not allow the surface to glow as much as the red LED, which has a lower energy level when compared to the green light. As a result, the red LED would not allow the surface to glow as well.
