Answer:
3.214 m
Explanation:
Here object is moving in a constant acceleration. Then we can use motion equations to find the total distance
V² = U² + 2as
0 = 1.5² + 2×-0.35 × s
s = 3.214 m
symbols has usual meanings.
Answer:
Spectra type M
Explanation:
mass spectrum is simply an intensity vs. m/z (mass-to-charge ratio) plot representing a chemical analysis. Hence, the mass spectrum of a sample is a pattern representing the distribution of ions by mass (more correctly: mass-to-charge ratio) in a sample. It is usually acquired using an instrument called a mass spectrometer. Not all the mass spectra of a given substance are same.
Answer:
Explanation:
Optical telescopes collect visible light. The three main types are reflecting telescopes, refracting telescopes, and catadioptric telescopes. Radio telescopes collect and focus radio waves from distant objects. Space telescopes orbit Earth, collecting wavelengths of light that are normally blocked by the atmosphere.
Option B
Electrons has a negative charge
<u>Explanation:</u>
Electrons are the negatively charged shreds of an atom. Collectively, the positive charge of the protons in the atomic nucleus are neutralized by each of the electrons of an atom engenders a negative charge. Electrons are notably meager associated with all of the distinct components of the atom.
Electrons enclose the nucleus. Because electrons travel so speedily, it is improbable to discern where they are at a distinct instant in time. Electrons perform a dominant position in whole chemical bonds.
In this item, we are asked for the word that would best fit in the blank of the sentence given above. The word that is missing in this item is "<em>evaporation</em>".
Evaporation is part of the water cycle wherein the liquid molecule of water is converted to water vapor and stays in the atmosphere until it is converted back to water for precipitation.
