The left ventricle relaxes and fills up with blood before squeezing and pumping the oxygen-rich blood through the aortic valve into the aorta — the main artery that carries blood to your body.<u>TRUE</u>
Answer:
Mass spectrometry is an analytical technique that measures the mass-to-charge ratio of ions. The results are typically presented as a mass spectrum, a plot of intensity as a function of the mass-to-charge ratio.
Explanation:
Tip your bucket into a mass spectrometer. It turns the atoms into ions Then it will separate the ions by passing them first through an electric field, then through a magnetic field, so they fan out into a spectrum
Answer:
5 ft/s²
Explanation:
u = Initial velocity = 100 ft/s
v = Final velocity = 0
s = Displacement = 1000 ft
a = Acceleration
From equation of motion


The airplane's deceleration is 5 ft/s² or 1.524 m/s²
Answer:
Action and Reaction
Explanation:
For every force, there is one of equal and opposite also. Think of it this way. When you try to push on a wall, you are applying a force. However, that wall is also pushing back on you with that same force. You can also see this when you high five someone. You can slap as hard as you want to their stationary hand, but due to the 3rd law, you're both going to be left with red hands do to the amount of force applied.
