Answer: Doctrine of ratification
Explanation:Doctrine of ratification tries to show that a person who is taking so much a time to complain has indicated that he agrees even if he doesn't without a written consent. This is to eliminate undue waste of time in business, legal an other proceedings requiring consent of both parties.
Doctrine of ratification can either be implied or expressed
Implied ratification is the type of ratification where a persons actions or body language can be seen that he has accepted.
Express ratification is a ratification where a person intentionally accept by showing either through written or verbally.
Elastic Potential Energy is zero detailed description is given below.
Explanation:
- It is the energy stored in stretched or compressed elastic materials. This also means that elastic potential energy is zero in objects that have not been stretched or compressed.
- To determine the gravitational potential energy of an object, a zero height position must first be arbitrarily assigned. Typically, the ground is considered to be a position of zero height. But this is merely an arbitrarily assigned position that most people agree upon. Since many of our labs are done on tabletops, it is often customary to assign the tabletop to be the zero height position. Again this is merely arbitrary. If the tabletop is the zero position, then the potential energy of an object is based upon its height relative to the tabletop. For example, a pendulum bob swinging to and from above the tabletop has a potential energy that can be measured based on its height above the tabletop. By measuring the mass of the bob and the height of the bob above the tabletop, the potential energy of the bob can be determined.
- Potential energy is the energy that is stored in an object due to its position relative to some zero position. An object possesses gravitational potential energy if it is positioned at a height above (or below) the zero height. An object possesses elastic potential energy if it is at a position on an elastic medium other than the equilibrium position.
Since the gravitational potential energy of an object is directly proportional to its height above the zero position, a doubling of the height will result in a doubling of the gravitational potential energy. A tripling of the height will result in a tripling of the gravitational potential energy.
Answer:
The required length of the wire is 15.637 m
The power dissipated is 1,216 W
Explanation:
Length (L) = resistance×area/resistivity
Resistance = 19 ohm
Area = 0.001276 in^2 = 0.001276in^2 × (2.54cm/1in)^2 = 8.23×10^-3 cm^2
Resistivity = 1×10^-4 ohm-cm
L = 19×8.23×10^-3/1×10^-4 = 1563.7 cm = 1563.7/100 = 15.637 m
Power = I^2 R = 8^2 × 19 = 64×19 = 1,216 W
Answer:
(a) BOD₅ = 138 mg/L
(b) BOD₅ = 115.2 mg/L
Explanation:
Given Data;
volume of sample = 15 mL
volume of sample bottle
Volume of dilution water = 285 mL
initial DO = 8.8 mg/L
Final DO = 1.9 mg/L
Calculating the volumetric fraction of the sample using the fromula;
p = volume of sample/volume of sample bottle
= 15/300
= 0.05
(a) Calculating the 5-day BOD of the waste water sample using the formula;
BOD₅ = D₀ - D₅/p
= 8.8 -1.9/0.05
= 138 mg/L
(b) Calculating the dilution percentage of sample, we have
Dilution percentage of sample = 285/300 *100
= 95%
Calculating the value of ratio f using the formula;
f = %of dilution water in diluted sample/%of dilution water in dilution water
= 95/100
= 0.95
Calculating the 5 day BOD of the waste water sample using the formula;
BOD₅ = [(D₀ - D₅) - f(B₀ -B₅)]/p
= [(8.8 - 1.9) - 0.95*(9.1 -7.9)]/0.05
= 6.9-1.14/0.05
= 5.76/0.05
= 115.2 mg/L
