The expanded-function dental assistant (EFDA) can play a
major role in the fabrication and temporary cementation of a provisional crown
or bridge. It is the dentist’s and the EFDA’s responsibility to remain current
with the new provisional materials and techniques that are available. It is
essential that a provisional crown or bridge remain cemented while the fixed
prosthesis is being prepared and delivered to the dental office. When the
patient returns for final cementation of a fixed crown or bridge, the
provisional should be cautiously removed without causing any fracture or harm,
just in case it will need to be recemented if the final prostheses needs to be
sent back to the lab for adjustments and remake.
Answer:
11
Explanation:
According to Boyle's law:
Thus,
Where, n is the number of the balloons
From the question, it is given that:
For balloon:
P = Pa
V = 0.040 m³
For cylinder:
P = Pa
V = 0.0031 m³
So,
n = 11.625
<u>So, Maximum number of balloons = 11</u>
The kinetic energy needed by the man is
Explanation:
The escape velocity (the speed needed by an object in the Earth's surface to escape the Earth's gravitational field) is given by
where
G is the gravitational constant
M is the Earth's mass
R is the radius of the Earth
For the Earth, we have
Substituting, we find the escape velocity:
Now we can find the kinetic energy that the man would need, which is given by
where
m = 65 kg is the mass of the person
is the escape velocity
Substituting,
