Answer:
There are equal parts reactants and products.
Explanation:
When a system is in a chemical equilibrium, the rate at which the forward reaction occur is the same as the rate at which the reverse reaction occurs. This system is said to undergo a reversible reaction. The concentration of the reactants and products do not change, i.e are constant.
In a chemical equilibrium, the reaction continues in both directions but at the same rate.
Therefore the statement that is a misconception about a system in chemical equilibrium is 'There are equal parts reactants and products'.
Answer:
The minimum effective focal length of the focusing mechanism (lens plus cornea) of the typical eye is 2.27 cm.
Explanation:
The diameter of person's eye is 2.5 cm. The close point or the near point of the eye is 25 cm and the far point is infinity. We need to determine the minimum effective focal length of the focusing mechanism (lens plus cornea) of the typical eye. Let f is the minimum effective focal length. It can be calculated using lens formula as :
f = 2.27 cm
So, the minimum effective focal length of the focusing mechanism (lens plus cornea) of the typical eye is 2.27 cm and it is at the nearest point. Hence, this is the required solution.
Answer:
Both technicians are correct
Explanation:
Because we are talking about a series circuit, both technicians are correct.
- <u>The total resistance of a series circuit is equal to the sum of each of all the individual resistances that make up the series circuit</u>, just as technician A says.
- And similarly <u>when adding the voltage in each of the resistences or components of the series circuit it should be equal to the source voltage</u>, the voltage supplied to the circuit, which is what Technician B says.
For these reasons the answer is that both A and B are correct.

Explanation:
From the question we are told that
The speed of the car is 
The length of the ramp is 
The constant velocity of the traffic 
Generally the acceleration of the car is mathematically represented as
Here u is equal to zero given that the car started from rest so
=>
Generally the time taken is mathematically represented as
=> 
=>
The distance traveled by the traffic is mathematically represented as
Here a is zero given that the traffic was moving at constant speed
=> 
=>
As per the question the body possesses kinetic energy but the net displacement of the particle is zero.
Before going to explain the type of motion first we have to know the basics of displacement.
The displacement is a vector quantity which has magnitude as well as direction .it is the minimum distance between two points out of all possible paths
Let us consider an example .let a body travels from point A to the point B and again comes to the back to the same point A .here the distance traveled is 2AB but the net displacement is zero.we have to apply this concept to solve this problem.
As the body possesses kinetic energy but the net displacement is zero .
This is in case of an circular motion.in circular motion the body possesses rotational kinetic energy but in every circular rotation ,the net displacement is zero.
One can take an example of oscillatory motion also.here the particle possesses vibrational kinetic energy ,but in each vibration ,the net displacement is zero.
