Distillation is a process in many laboratories for the purpose of
separating and/or purifying components of a liquid mixture. The distillation apparatus used consists of
three major parts: <span>distillation flask - to heat the mixture and volatilize the components,
a condenser to cool the vapors back to liquid state, and a collection vessel. The apparatus is typically made of glass and
therefore subject to breakage.</span> <span>All components of the distillation apparatus
should be protected to a stable stand or rack to avoid it from falling over.</span>
Answer:
75457.54816 N
Explanation:
= Initial force
= Weight of car = 11547.83 N
= Smaller radius = 5 cm
= Larger radius = 19.56 cm
From Pascal's law we have
The force is 754.57548 N
Kinetic energy and velocity are at zero when the magnets are held apart, and both increase rapidly when they are released and move together. Energy stored in the magnetic field decreases.
Answer:
the answer is C
Explanation:
C) friction - mechanical - electrical
Answer:
The period is 9.9 seconds
Explanation:
The period (T) of a mass (m) attached to a spring with spring constant k is:
(1)
So, if the mas is M we have that:
(2)
Now if we double the mass:
(3)
Because spring constant doesn’t change, we note that the term on (3) is equal to the right side of (2), so we have:
