DV FORMULA. Total base (g) = (no. of suppositories x mould size) – Total drug (g) DV For example, a DV of 0.7 means that 0.7 g of drug displaces 1 g of the base. There are several methods which we can use with questions relating to displacement values and suppositories.

What is the formula for displacement in physics?
In Physics, we can calculate displacement by calculating the distance between the initial position and the final position of the object. In Physics, often displacement is referred to as the variable s. The displacement formula is as follows: s = sf – sf.
How do you solve distance and displacement?
What is total displacement in physics?
The displacement is simply the difference in the position of the two marks and is independent of the path taken when traveling between the two marks. The distance traveled, however, is the total length of the path taken between the two marks.
What is the displacement value?
Displacement Value can be defined as the volume of drug that displaces 1 gram of suppository base. The most commonly used suppository base is Coca Butter or Theobroma oil. Traditionally suppositories are prepared using suppositories molds which can generally hold 1 gram or 2 gram of base.
How do you calculate volume displacement?
What is a displacement volume?
Definition of volume displacement : displacement of a fluid expressed in terms of volume as distinguished from displacement expressed in terms of mass.
What is displacement in velocity?
The displacement, defined as the change in position of the object, is a vector with the magnitude as a distance, such as 10 miles, and a direction, such as east. Velocity is a vector expression with a magnitude equal to the speed traveled and with an indicated direction of motion.
What is displacement in physics class 11?
Displacement is defined as the change in position of an object. It is a vector quantity and has a direction and magnitude. It is represented as an arrow that points from the starting position to the final position. For example- If an object moves from A position to B, then the object’s position changes.
How do we calculate distance?
distance = speed × time. time = distance ÷ speed.
How do you find displacement with velocity?
Velocity (v) is a vector quantity that measures displacement (or change in position, Δs) over the change in time (Δt), represented by the equation v = Δs/Δt.
What is an example of displacement in physics?
Let us consider a passenger moving to the rear end relative to the airplane as another of the examples of displacement. If a passenger starts from 5.0 m, travels to the rear end of the plane, and stops at 2.0 m, then the displacement equals ∆x = 2.0 m – 5.0 m = – 3.0 m.
Is displacement the same as velocity?
Displacement is the vector difference between the ending and starting positions of an object. It may be very different from the distance the object has travelled along the way. Velocity is the rate at which displacement changes with time.
Why do we need to calculate displacement value?
Displacement values are important when it comes to reconstituted powders. If a solution were 10mL more than the solution needed, it would dilute the concentration and consequently dilute the dose. For this reason, density and displacement values play an important role in pharmacy and pharmaceutical calculations.
What is a displacement factor?
displacement factor (cos φ1) means the cosine of the phase angle φ1 between the fundamental harmonic of the mains supply voltage and the fundamental harmonic of the mains current. It is used for mains light sources using LED- or OLED-technology.
What is displacement value explain it with suitable example?
These values are referred to as displacement values. For example, the displacement value of zinc oxide is 4.7. This means that 4.7 g of zinc oxide will displace (or occupy the space of) 1 g of theobroma oil (the suppository or pessary base). In other words, zinc oxide is much more dense than theobroma oil.
What is displacement into area?
Answer: In physics, work is energy transferred to an object via the application of force along a displacement, it is called product of area and displacement.
What is the displacement of water?
When an object enters water, it pushes out water to make room for itself. The object pushes out a volume of water that is equal to its own volume. This is called displacement.
What is the method of displacement?
Displacement is usually the method that is used to measure the volume of an irregularly shaped object. The object is simply submerged in a liquid and the volume of liquid that is displaced is measured.
How do you calculate water displacement?
To find the amount of water displaced, students should subtract the initial level of the water (60 mL) from the final level of the water.
What is matter displacement?
displacement, in mechanics, distance moved by a particle or body in a specific direction. Particles and bodies are typically treated as point masses—that is, without loss of generality, bodies can be treated as though all of their mass is concentrated in a mathematical point.
Is displacement the same as distance?
People sometimes think that distance and displacement are just different names for the same quantity. However, distance and displacement are different concepts. If an object changes direction in its journey, the total distance traveled will be greater than the displacement between those two points.
How do you find displacement from acceleration?
a=dtd(ds/dt)=dt2d2s. The acceleration is the second time derivative of the displacement. As before, the velocity and the displacement follow from the acceleration by integration with respect to time, once in the case of velocity and twice to obtain the displacement.
What is the total displacement of the object?
Displacement is the change in position of an object. The SI unit for displacement is the meter. Displacement has direction as well as magnitude. Distance traveled is the total length of the path traveled between two positions.
