Q:

Consider the following statements :

1. There is no net moment on a body which is in equilibrium.

2. The momentum of a body is always conserved.

3. The kinetic energy of an object is always conserved.

Which of the statements given above is/are correct?

A) 1, 2 and 3 B) 2 and 3 only
C) 1 and 2 only D) 1 only
 
Answer & Explanation Answer: C) 1 and 2 only

Explanation:

There are two conditions that must be met for an object to be in equilibrium. The first condition is that the net force on the object must be zero for the object to be in equilibrium. If net force is zero, then net force along any direction is zero.

Kinetic energy (KE) is the energy of motion, and kinetic energy is not always conserved in a collision

Energy and momentum are always conserved.

Q:

Read the passage carefully and choose the best answer to each question out of the four alternatives.


Prebiotics are the lesser-known gut-health promoters which serve as food for good bacteria inside the gut. "We found that dietary prebiotics can improve non-REM (random eye movement) sleep, as well as REM sleep after a stressful event," said Robert Thompson, a PhD researcher at University of Colorado Boulder in the U.S. Prebiotics are dietary fibres found naturally in foods like artichokes, raw garlic, leeks and onions.

When beneficial bacteria digest prebiotic fibre, they not only multiply, improving overall gut health, but they also release metabolic by-products. Researchers fed three-week-old male rats a diet of either standard chow or chow that included prebiotics. They then monitored the rats' body temperature, gut bacteria and sleep-wake cycles — using electroencephalogram (EEG), or brain activity testing over time. Findings revealed that the rats on the prebiotic diet spent more time in non-rapid-eye-movement (NREM) sleep, which is restful and restorative, than those on the non-prebiotic diet.


How are metabolic by-products released?

A) When good bacteria help sleep B) When good bacteria digest dietary fibres
C) When gut becomes rich in nutrients D) After recovery from stress due to sleep
 
Answer & Explanation Answer: B) When good bacteria digest dietary fibres
