Describe the motion shown in the lines
Bogdan [553]

Answer:

Solution

For figure (a)

During interval AB Velocity is +ve, so the particle is moving in +ve direction, but it is slowing down as acceleration (slope of v-7 curve) is negative.

During interval BC Particle remains at rest as the velocity is zero. Acceleration is also zero.

During interval CD Velocity is -ve, so the particle is moving in -ve direction and is speeding up as acceleration is also negative.

For figure (b),

During interval AB Particle is moving in +ve direction with constant velocity and acceleration is zero.

During interval BC Particle is moving in +ve direction as velocity is +ve, but it slows down until it comes to rest as acceleration is negative.

During interval CD Velocity is -ve so the particle is moving in -ve direction and is speeding up as acceleration is also negatived

Lapatulllka [165]

Answer:

On the left is negative charge while on the right is positive charge.

Explanation:

On the left, there should be negative charge that will move away due to repulsion force because both charges are same so they move away from one another while on the other hand, on the right side there should be positive charge which will move towards it because both charges are opposite to each other so they attract each other.

Wernicke-korsakoff syndrome is associated with the decreased absorption and utilization of:______
Mariulka [41]

Wernicke-korsakoff syndrome is associated with the decreased absorption and utilization of thiamin. The correct answer is c. thiamin..

The neurological condition Wernicke-Korsakoff syndrome is brought on by a lack of vitamin B1 (thiamin). There is no distinction between Korsakoff syndrome and Wernicke encephalopathy. The disease process is the same but at various stages. Both result from brain damage brought on by a deficiency in vitamin B1.

A prevalent deficiency in vitamin B1 is found in patients with alcohol use disorders. Additionally, it frequently affects persons whose bodies do not adequately absorb meals (malabsorption). This can occasionally happen after bariatric surgery or in conjunction with a chronic condition.

Following the disappearance of Wernicke encephalopathy symptoms, Korsakoff syndrome frequently appears. The thalamus and hypothalamus, two lower regions of the brain, are damaged as a result of Wernicke encephalopathy. Memory-related brain regions suffer permanent harm in people with Korsakoff syndrome.
