Answer:
Explanation:
This problem is all about torque. The "rules" are that in order for a system to be in rotational equilibrium, the sum of the torques on the system have to equal 0 (in other words, they have to equal each other {cancel each other out}). The equation for torque is
τ = F⊥r where τ is torque, F⊥ is the perpendicular force, and r is the lever arm length in meters. We also have to understand that in general Forces moving clockwise are negative and Forces moving counterclockwise are positive. Now we're ready for the problem:
A. The counterclockwise torque:
τ = 300(3) so
τ = 900N*m
B. The clockwise torque:
τ = -450(2.5) so
τ = -1100N*m
C. Obviously the system is not in roational equilibrium because one side is experiencing a greater torque than the other. This system will move clockwise as it currently exists.
D. In order for the system to be in rotational equilibrium, we have to move Bob's location from the fulcrum. Let's see to where.
The torques have to be the same on both sides of the fulcrum; mathematically, that looks like this:
F⊥r = F⊥r Filling in:
300(3) = 450r and
900 = 450r so
2 = r. This means that Bob will have to move closer to the fulcrum by a half of a meter to 2 meters from the fulcrum in order for the system to be in balance.
Isn't this so much fun?!
As a wavelength increases in size, its frequency and energy (E) decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter. ... Mechanical and electromagnetic waves with long wavelengths contain less energy than waves with short wavelengths.
Is this your Question:
Read the hypothetical situation below and answer the question that follows.
In response to criticisms that the King of Mordor has failed to gain the consent of his people, the King claims that he does in fact represent the consent of the people because without their King, society would crumble into chaos.
Which statement BEST represents a rebuttal that Rousseau would use to counter the King's argument?
A.
Absolute chaos is preferable to the absolute power of the King.
B.
The King of Mordor should establish a system of checks and balances.
C.
If the King of Mordor were to represent the will of his people, then he would at least provide the public services demanded by his people.
D.
It is impossible for the King of Mordor to have the consent of the people because the monarchy is not a freely formed government in which the people have a say in how it operates.
If this is your question.. Here is your Answer:
Answer: D.
It is impossible for the King of Mordor to have the consent of the people because the monarchy is not a freely formed government in which the people have a say in how it operates.
Explanation:
Rousseau believed that sovereignty (the power to make laws) belonged to the people, not one person, and that it should be carried out by a representative body of the people who are elected by them on their behalf. While he agreed society requires a ruler(s), he thinks they should be chosen by the people.
Answer: The correct answer for the blank is- Replication.
DNA replication is a biological process in which two identical replica of DNA are produced from single original DNA molecule through an enzyme called as DNA polymerase.
The two strands of double helical DNA are first separated ( with the help of helicase enzyme) so that the template DNA strands are exposed. In other words, the two strands are broken apart and attract new nucleotide bases to synthesize a new and complete strand of DNA.
This is done by DNA polymerase according to Watson and Crick base pairing ( A pairs to T, G pairs to C)
Answer:
Explanation:
Given
mass of car 
Vertical displacement 
spring constant 
Considering we need to find out compression in the spring when it reaches to ground
Here Gravitational potential Energy is converted to kinetic energy which finally converts to Elastic Potential Energy
suppose x is the compression in spring
Potential Energy=mgh
Elastic potential energy
