Discuss the role of the expanded functions dental assistant in making a provisional coverage

Physics
1 answer:
dedylja [7]4 years ago
7 0

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.

Momentum is usually not exactly conserved in a real world demonstration of momentum conservation. What is a possible reason for
Maksim231197 [3]

Answer:

For any collision occurring in an isolated system, momentum is conserved. The total amount of momentum of the collection of objects in the system is the same before the collision as after the collision.

A student releases a block of mass m at the top of a slide of height h1. the block moves down the slide and off the end of the t
Virty [35]

Answer:

B)   d = √  ( 4 h₂ ( H - 2h₂))

Explanation:

A) 1) If the height of the slide is very small, there is no speed to leave the table, therefore do not recreate almost any horizontal distance

2) If the height is very small downwards, it touches the earth a little and the horizon is small,

B) to find an equation for horizontal distance (d)

We must maximize the speed at the bottom of the slide let's use energy

Starting point Higher

          Em₀ = U = m g h₁

Final point. Lower (slide bottom)

            Emf = K + U = ½ m v² + m gh₂

As there is no friction the energy is conserved

             mgh₁ = ½ m v² + mgh₂

             v² = 2 g (h₁-h₂)

This is the speed with which the block leaves the table, bone is the horizontal speed (vₓ)

The distance traveled when leaving the table can be searched with kinematics, projectile launch

           x = v₀ₓ t

          y = v_{oy} t - ½ g t²

The height is the height of the table (y = h₂), as it comes out horizontally the vertical speed is zero

         t = √ 2h₂ / g

We substitute in the other equation

         d = √ (2g (h₁-h₂))  √ 2h₂ / g

         d = √ (4 h₂ (h₁-h₂))

         H = h₁ + h₂

         h₁ = H -h₂

         d = √  ( 4 h₂ ( H - 2h₂))

A 120 Ω resistor, a 60 Ω resistor, and a 40 Ω resistor are connected in parallel and placed across a potential difference of 12.
Westkost [7]

Answer:

The equivalent resistance of the parallel circuit would be 20 Ω

Explanation:

To calculate the resistance of resistors connected in parallel, the formula to be used is

1/R = 1/R₁ + R₂ + R₃ + R₄...

1/R = 1/120 + 1/60 + 1/40

1/R = (1 + 2 + 3)/120

1/R = 6/120

1/R = 1/20 Ω

This can be rewritten or cross-multiplied to be

R × 1 = 20 × 1

R = 20 Ω

The equivalent resistance (R) would then be 20 Ω

Sometimes, even with a wrench, one cannot loosen a nut that is frozen tightly to a bolt. It is often possible to loosen the nut
DIA [1.3K]

Answer:

Explanation:

Torque is defined as the product of force and the perpendicular distance from the application of force.

It is a vector quantity.

Torque = force x perpendicular distance

To loosen a nut, if we increase the amount of distance, the torque is increased by applying a little amount of force and hence it is easy to open the nut.

Thus, it is easy to open a nut by slipping one end of a long pipe over the wrench handle and pushing at the other end of the pipe so that the torque is more and the nut is loosen.
