What Is The Value Of Retardation?

What is retardation short answer?

Retardation is nothing but a negative acceleration.

The velocity of the body may either increase or decrease.

The change in velocity is known as acceleration.

Retardation is acceleration with a negative sign.

Or the negative value of acceleration shows that the velocity of a body is decreasing..

What causes retardation?

Illness or injury. Infections like meningitis, whooping cough, or the measles can lead to intellectual disability. Severe head injury, near-drowning, extreme malnutrition, infections in the brain, exposure to toxic substances such as lead, and severe neglect or abuse can also cause it.

Can mental retardation be reversed?

“The same mutation in animals produces learning disorders, which we were able to eliminate in adult mice. Our work and other recent studies suggest that some forms of mental retardation can be reversed, even in the adult brain.”

What is formula of retardation?

The formula of retardation is acceleration =final velocity(v)-initial velocity(u) \ time taken.

Is retardation positive or negative?

Acceleration takes place when the velocity of a body changes. So when the velocity of a body increase, the acceleration is said to be positive and when the velocity of a body decrease, the acceleration is said to be negative(Retardation).

What are the 4 levels of mental retardation?

The DSM-IV classifies mental retardation into four stages based on severity: mild (IQ score of 50-55 to approximately 70), moderate (IQ score of 30-35 to 50-55), severe (IQ score of 20-25 to 35-40), and profound (IQ score of less than 20-25).

What is retardation example?

Negative acceleration is called retardation. If the velocity of a body is decreasing with respect to time, the acceleration is said to be negative. Examples of retardation motion are: 1) Velocity of vehicle decreases when brake is applied.

Why is the retardation factor important?

The retention factor of a particular material is the ratio of the distance the spot moved above the origin to the distance the solvent front moved above the origin. … Retention factors are useful in comparing the results of one chromatogram to the results of another.

Is mental retardation curable?

A small study of 30 people with the most common inherited form of mental retardation has found encouraging evidence that some symptoms of the disorder can be alleviated with drugs.

What is the most common cause of mental retardation?

Down’s syndrome is the most common specific cause of mental retardation, followed by the Fragile X syndrome, which mainly affects boys.

What is difference between velocity and speed?

Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object’s movement. Put another way, speed is a scalar value, while velocity is a vector.

What is retardation effect?

Retardation effects are due to the electromagnetic field needing to travel for a long time to reach the neighboring atom when the separation distance is long.

In which condition retardation is possible?

If your child has an intellectual disability (ID), their brain hasn’t developed properly or has been injured in some way. Their brain may also not function within the normal range of both intellectual and adaptive functioning. In the past, medical professionals called this condition “mental retardation.”

What happens when acceleration is zero?

Acceleration is the rate at which an object’s speed and direction are changing with time, so whenever an object passes through zero speed as it reverses directions it has a non-zero acceleration but a speed of zero. … It’s still accelerating downward during that motionless instant, but its speed is zero.

What displacement means?

The word displacement implies that an object has moved, or has been displaced. Displacement is defined to be the change in position of an object.

What is the symbol of retardation?

Answer:There is no symbol for retardation. It is written as ‘retardation’ only.

What is uniform acceleration?

BSL Physics Glossary – uniform acceleration – definition Translation: If an object’s speed (velocity) is increasing at a constant rate then we say it has uniform acceleration. The rate of acceleration is constant. If a car speeds up then slows down then speeds up it doesn’t have uniform acceleration.

Which type of motion is circular motion?

In physics, circular motion is a movement of an object along the circumference of a circle or rotation along a circular path. It can be uniform, with constant angular rate of rotation and constant speed, or non-uniform with a changing rate of rotation.
