find potential at a point on the line , containing two charges " q " and " 4q " at a distance of " r " metres , where net E due to these charges is same.
The potential at a point on the line will be,[tex]\rm E_{net}=\frac{5Kq}{r}[/tex].The net potential is the algebraic sum of the electric potential.
What is the electrical potential difference?The amount of work performed in an electrical field to move a unit charge from one location to another is defined as the electrical potential difference.
In other terms, the potential difference is the difference in electric potential between two charged substances.
The traditional current flow is from positive to negative terminals, indicating the movement of positive charges in that direction.
[tex]\rm E_1 = \frac{Kq}{r} \\\\ E_2=\frac{K(4q)}{r}[/tex]
The potential at a point on the line is found as;
[tex]\rm E_{net}=E_1+E_2 \\\\\ E_{net}=\frac{Kq}{r} +\frac{K(4q)}{r} \\\\E_{net}=\frac{5Kq}{r}[/tex]

a steam engine work on its vicinity 285 k heat is released with the help of 225 c energy absorbed to the system what is the efficiency of steam engine explain the use of the rest of the energy physic problem
The efficiency of the steam engine is 78.9% because the rest of the work input is used to overcome friction.
What is efficiency of machines?Efficiency of a machine expresses the useful work done by a a machine as a percentage.
Efficiency of a machine = work output/work input × 100 %%The efficiency of machines are always less than 100% percent due to energy losses due to friction and heat.
For the steam engine:
Work output = 225 J
Work input = 285 J
Efficiency = 225/285 × 100% = 78.9 %

Select one:
500 kJ
The energy needed to vaporize 100 grams of ice at starting at 0°C is 300.83 kJ.
What is heating?When the temperature is increased , the body or particle is said to be heating.
Given is the mass of water =100g =0.1 kg, Latent heat of fusion L = 333.7 kJ/kg,
Energy required to melt ice into water at 0°C.
Q₁ = mL
Q₁ = 0.1 x 333.7
Q₁ = 33.37 kJ
Energy required to heat water from 0°C to 100°C is
Q₂ = mCΔT

food does not pass through the liver or the pancreas why are these organs dtill important parts of the digestive system?
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.

Electrical conductivity often decreases, when elements receive additional electrons in their outer shells. As a result of the valence shell being filled, the number of movable electrons decreases.
What is a mobile electron?Electrons are mobile charges in the conduction band while holes are mobile charges in the valence band.
Current flow in a semiconductor is caused by charge carrier migration in both the conduction and valence bands.
Which creates a net motion of positively charged carriers in the same direction as the field and negatively charged carriers in the opposite direction as a result of the force.
The outermost electrons in metals are not bonded to each atom which is shared by many atoms. This decentralization is what allows metals to conduct electric currents.
