Your pancreas makes a digestive juice that has enzymes that break down carbohydrates, fats, and proteins. The pancreas delivers the digestive juice to the small intestine through small tubes called ducts. Liver. Your liver makes a digestive juice called bile that helps digest fats and some vitamins.
Digestive enzymes are made by the pancreas and aid in the breakdown of proteins, carbs, and lipids. Bile, a liquid made by the liver that aids in fat digestion, is produced.
What is meant by digestive system ?The digestive system breaks down the food we consume into its most basic components, such as glucose (sugar), amino acids (which make up protein), or fatty acids (which make up lipids).
Here,
The digestive system of humans is made up of a fully formed alimentary canal and the glands that are located there. The alimentary canal, which includes the mouth, oral cavity or buccal cavity, pharynx, oesophagus, stomach, small intestine, large intestine, and anus, is encircled by glandular epithelium.
The nutrients from the digested food are subsequently transported to every cell in the body thanks to absorption into the bloodstream from the small intestine.
Although they are not a part of the alimentary canal, the pancreas, which is located beneath the stomach, the gallbladder, and the liver are all vital for digestion.
Hence,
Digestive enzymes are made by the pancreas and aid in the breakdown of proteins, carbs, and lipids. Bile, a liquid made by the liver that aids in fat digestion, is produced.

A lamp with a resistance of 60 Ohms is plugged into a 110-Volt household circuit. How much current flows through the lamp?
The current flowing through the lamp is 1.833A
What is current?The current is the stream of charges which flow inside the conductors when connected across the end of voltage.
From the Ohm's law, V =IR
Here, R is the proportionality constant called resistance of the resistor
A lamp with a resistance of 60 Ohms is plugged into a 110-Volt household circuit.
I = V/R
Put the values, we get
I = 110/60
I = 1.833A
Thus, the current flowing through the lamp is 1.833A

a body covers a distance of 20 m in 2 second and then covers 40 metre in next it s8 on a straight line calculate its velocity
Answer:
6 m/s
Explanation:
Average velocity = Total distance covered / Time taken to cover distance
Finding Average Velocity :
⇒ 20 m + 40 m / 2 s + 8 s
⇒ 60 m / 10 s
⇒ 6 m/s
a body covers a distance of 20 m in 2 second and then covers 40 metre in next it s8 on a straight line calculate its velocity.
Solution:AV = 20m + 40m/s 2s + 8secondAV = 60m/s ÷ 10sAV = 6m/s²So the Average velocity is 6m/s²

?How much work is done by 5 kg water as it is evaporated at 10 bar pressure
Answer:
The (latent) heat of vaporization (∆Hvap) also known as the enthalpy of vaporization or evaporation, is the amount of energy (enthalpy) that must be added to a liquid substance, to transform a given quantity of the substance into a gas.
The enthalpy of vaporization is a function of the pressure at which that transformation takes place. The heat of vaporization diminishes with increasing temperature and it vanishes completely at a certain point called the critical temperature (Critical temperature for water: 373.946 °C or 705.103 °F, Critical pressure: 220.6 bar = 22.06 MPa = 3200 psi ).

In the video, the students create two charged tapes, a "pointy" tape and a "square" tape. The pointy tape is first placed on top of the square tape, and the two are pulled apart. After pulling them apart, the students observed the behavior of the tapes when they were brought near each other, but not touching each other.
The two pointy tapes repel. This shows they have the same type of charge.
Attraction of two chargesThe attraction of two charges occurs when the two charges have opposite charges.
Repulsion of two chargesThe repulsion of two charges occurs when the two charges have similar charges.
Thus, since the two pointy tapes will have the same charge, we can conclude that they will repel each other when brought near each other.

An object has an initial velocity of 15 m/s and a constant acceleration of 4 m/s2. How long will it take before its final velocity is equal to three times its initial velocity?
Based on the calculations, it would take 7.5 seconds before the final velocity of this object would be equal to three times its initial velocity.
Given the following data:
Initial velocity = 15 m/s.Constant acceleration = 4 m/s².Final velocity = 3 × 15 = 45 m/s.How to calculate the acceleration of an object?Mathematically, acceleration can be calculated by using the first equation of motion:
v = u + at
Where:
v is the final velocity.u is the initial velocity.t is the time measured in seconds.Making t the subject of formula, we have:
t = (v - u)/a
Substituting the given parameters into the formula, we have:
