Chyme is a semi-liquid paste that results from the mixing of partially digested food with gastric juice in the stomach.

When food enters the stomach, the gastric gland releases gastric juice, which the stomach's muscular wall thoroughly stirs into the meal. Chyme is the term for partially digested food that contains gastric juice.

Only a small amount of chyme is released into the small intestine at a time. The movement of chyme from the stomach into the small intestine is regulated by the pyloric sphincter.

In contrast, chyle is a milky body fluid made up of lymph and free fatty acids that have been emulsified (FFAs). While roughage refers to the inorganic fibre included in food, it is generated in the small intestine after the breakdown of fatty foods and taken up by lymph channels specifically known as lacteals.

Aneli [31]

Answer:
180 meters

Explanation:
Josh walks 6 meters to the right and the 6 meters back. This means that in one time, Josh walks a total distance of 6+6 = 12 meters
Now, we are given that Josh walks this same distance 15 times.
Therefore, we will multiply this distance by 15 to get the total distance that he walks as follows:
Total distance = 12*15 = 180 meters

Based on the above calculations, Josh walks 180 meters over the course of the class

Hope this helps :)

A Gatorade bottle is dropped on a waterslide. It accelerates at 4.0 m/s2 for 9.0s from rest. What is the slide’s length?

Goryan [66]

With an acceleration of 4.0 m/s², the bottle attains a speed of

(4.0 m/s²) * (9.0 s) = 36 m/s

so that the slide has length ∆x such that

(36 m/s)² - 0² = 2 * (4.0 m/s²) * ∆x

==> ∆x = 162 m ≈ 160 m

Alternatively, we know the bottle covers a distance ∆x with acceleration a at time t according to

∆x = 1/2 a t²

so that

∆x = 1/2 * (4.0 m/s²) * (9.0 s)² = 162 m ≈ 160 m

How much force is needed to accelerate a 5-kg object at 4 m/s2

Alecsey [184]

F = m · a (Newton's 2nd law of motion)

F = (5 kg) · (4 m/s )

F = 20 Newtons

To change a tire, you need to use a jack to raise one corner of your car. While doing so, you happen to notice that pushing the

Alja [10]

Answer:

Explanation:

The energy lost by the handle in lowering is equal to the energy gained by the car in raising the height.

As the mass of car is much more as compared to the jack, so the height raised by the car is very small as compared to the handle of jack.

A fisherman notices that his boat is moving up and down periodically without any horizontal motion, owing to waves on the surfac

taurus [48]

Answer:

a. Speed = 1.6 m/s

b. Amplitude = 0.3 m

c. Speed = 1.6 m/s

Amplitude = 0.15 m

Explanation:

The frequency of the wave must be equal to the reciprocal of the time taken by the boat to move from the highest point to the highest point again. This time will be twice the value of the time taken to travel from the highest point to the lowest point:

frequency = $\frac{1}{2(2\ s)}$ = 0.25 Hz

The wavelength of the wave is the distance between consecutive crests of the wave. Therefore,

Wavelength = 6.4 m

Now, the speed of the wave is given as:

Speed = (Frequency)(Wavelength)

Speed = (0.25 Hz)(6.4 m)

Speed = 1.6 m/s

Amplitude is the distance between the mean position of the wave and the extreme position. Hence, it will be half the distance between the highest and lowest point:

Amplitude = (0.5)(0.6 m)

Amplitude = 0.3 m

frequency = $\frac{1}{2(2\ s)}$ = 0.25 Hz

Speed = (Frequency)(Wavelength)

Speed = (0.25 Hz)(6.4 m)

Speed = 1.6 m/s

Amplitude = (0.5)(0.3 m)

Amplitude = 0.15 m
