7. A some s dropped from the top of a tower 500 m high into a pond of water at
the base of the tower. When is the splash heard at the top ?
= 10 ms and speed of sound = 340 ms?)​

Answers

Answer 1

Answer:

11.47answer

Explanation:

Height of the tower, s = 500 m

Velocity of sound, v = 340 m sˆ’1

Acceleration due to gravity, g = 10 m sˆ’2

Initial velocity of the stone, u = 0 (since the stone is initially at rest)

Time taken by the stone to fall to the base of the tower, t1

According to the second equation of motion:

S = ut1 + 1/2gt12

500 = 0 x t1 + 1/2 x 10 x t12

t12 = 100

t1 = 10s

Now, time taken by the sound to reach the top from the base of the tower, t2= 500/340 = 1.47 s

Therefore, the splash is heard at the top after time, t

Where, t= t1 + t2 = 10 + 1.47 = 11.47 s.

Answers

Answer: Needles contaminated with blood

Explanation:

Blood is to be considered as an infectious waste because it can contain substances that lead to infections. Blood on needles or other sharp objects is of even more concern because there is a greater risk of infection.

Needles that are contaminated with blood should therefore be treated as infectious and put in an autoclave bag for disinfection and sterilization.

Describe how the digestive system responds differently to foods high in starchy carbohydrates with and without fiber as part of the same meal.

Answers

Answer:

The reasons for the altered rates of digestion include fiber, food form, the nature of the starch, antinutrients etc. Through reducing the rate of digestion of starchy foods post prandially "slow release" starchy foods blunt many gut hormone responses, and prolong FFA and ketone body suppression.

In the presence of fiber the digestive system reduces the rate of digestion of starch, as a result, the starch gives energy slowly which is good for health.

Digestion of Starch:

It starts digesting in the mouth during chewing by saliva. Starch is mainly digested in the small intestine.

Here, amylase breakdown the starch into small fragments and finally into glucose.

The digestive system cannot break down the fiber because the human digestive system does not have enzymes to break down.

Therefore, in the presence of fiber the digestive system reduces the rate of digestion of starch, as a result, the starch gives energy slowly which is good for health.
